Amazing and well done. We live in a remarkable time where so many of these components are readily available and affordable. for viewers: before cutting the molinex connector look for any pin with an additional (usually thinner) wire, and for the orange or brown wire in pin 11/20 or 13/24, these are 'sense' wires and must be connected so that the power supply knows it's working or else it shuts down immediately. Also google the model of your power supply for minimum load(s), some only need 1 amp load on the 5v line, some need 0.5amp on the 3.3v, 5v, AND the 12v lines. The variable stepdown output unit needs a diode on the output to protect against feedback if you use if for battery charging or anything with capacitence/inductance such as a motor. I might also suggest circuit breakers instead of fuses for the 3.3,5,12v lines.
I am 70 years old and retired from Tennessee USA. I enjoy your videos more than any others on RUclips. I’m just starting out trying to learn basic woodworking. You make me wish I would have spent my entire life learning the skills you have. Thank you very much for sharing. Do you have a patron page? I would love to support your work. Thanks again.
I'm glad to hear that. I'm 44 years old now and I also wish I had started this woodworking and handicraft thing when I was younger. But better late than never. I haven't yet a patreon page.
I've been planning to build an ATX power supply for several months. Of all the designs I've seen, yours is best for my needs and limited space. Well done!
well i do love his highly skilled workmanship. A couple points from an electronic engineer of over 50years skills. 1. I would recommend not having air in and air out on back panel, unless there is some form of horizontal separation barrier sticking back at least 200mm from one side to the other. I note as other have pointed out there are grills on the back panel situated above the fan outlet grill. Now if unit is placed with back near a wall or rear of bench with a high back the air will start to recirculate and unit will get hot. His case is beautifully designed and made, except for this critical thermal flaw. Look at any type of commercial equipment and you will never see inlet and exhaust placed adjacent to each other. Further like the desk top computers these supplies are filled to, I would suggest adding a removable filter on any inlet air vent as a major killer of these supplies is both dust (causes electrical arcing in the High voltage DC section of the supply) and overheating. 2nd personally I would have painted the inside of the case with a fire resistant paint or lined it with a thin fire resistant material. But that's me, very safety conscious. Absolutely brilliant video. I will do say you have taught me a lot about building in timber. Plus you mentioned some sort of cad software I had not heard of, that I will look up as I have recently got myself a 3D printer. Also EXCELLENT graphic schematic showing how to wire unit. I have to ask what did you draw that in please?
INCREDIBLE Workmanship. May I offer ONE suggestion? Instead of cutting ALL of the wires from the Power Supply, get a Power Supply MOLEX connector from a defective motherboard, and solder all your wires to it. Then you can just use the standard Power Supply output plug to attach to your wiring harness. Someday your Power Supply will FAIL. So when it does, you can simply UNPLUG it and replace it with another in just a few minutes.
An even easier way is you can buy a board of ebay for about $10 that has the molex connector, banana sockets for all voltages, already fused and has an LED and on/off switch. Just plug it in and you're ready to rock'n'roll.
there used to be 24-20 pin converters for using a new power supply with a 20-pin motherboard, on those, wires are already in, so maybe that will be even easier? something like this: www.cableleader.com/6-atx-20-pin-female-to-24-pin-male-motherboard-adapter-cable.html
PaintmanJohn & Eric Livesay - could either (or both) of you *please* explain to me where you obtained your knowledge on this subject matter?? I’m 40 and I’m desperate to learn about ALL THINGS low voltage / DC related, but I’ve got no clue where to start!! I’ve watched SO MANY VIDEOS like this one, from start to finish, and marvel at the amazing achievements & know-how of Numerous creators... I’ve even purchased some basic soldering & wiring kits/equipment and also own & tried to learn several different things like arduino, raspberry pi, and even projects with led bulbs or infrared arrays... I get started, and then quickly get LOST every time. I’m also very fond of finding discarded electronics and either fixing them or just breaking them down to see how they look inside... every week I bring home something new, like laptops, TV’s, monitors, radios, etc, which I find ON THE CURB in my neighborhood... I recently broke down a huge Plasma TV and I’m CERTAIN there are valuable components inside of it that could be used in future projects, but since I’m clueless, I’ve stacked up all the boards from all these dismantled items and piled them neatly in boxes... hoping SOME DAY I’ll understand what I’m looking at... The fact that you guys can watch this video and not only FULLY UNDERSTAND IT, but then offer ADVICE on how to do this BETTER simply blows my mind and frustrates me. HOW DO YOU KNOW???? I would die a happy man if I knew how to build something like this or simply UNDERSTAND what’s being built to the level where I felt I could easily replicate it if I chose to... Could you guys please explain to me how I can obtain a thorough education & understanding on all things involved here in this video?? You were blessed with this education and had to start somewhere, so please help me. Cheers!
Best DIY tutorial of ANY I've seen on RUclips ! The attention to detail is what impressed me first, but then the inclusion of slight mistakes and the corrections taken is what really won me over and makes this a true DIY video.
Excellent build. I had a bench top supply that I made when I first started with Arduinos. I found that for many projects I needed more than 12 volts, but I rarely needed more than two voltage inputs simultaneously. To keep the footprint small I made mine with two variable outputs using the same modules you used. I made it so I can use a power supply from a laptop or any other type of supply using the same size male jack. The main power supply sits on the floor out of the work area and only the variable control and outputs are on the bench top. Adding multiple female jacks makes it possible to use any supply I happen to have available whether it has a barrel jack like my old Toshiba laptop or a rectangular one like my wife’s Lenovo. I can also use the power supply for my 3D printer or even my model railroad. It is very inexpensive if you shop carefully for the components.
Finally, someone designed it the way I was working towards .... last ???. All 3 separate standard voltages, adjustable up to 24v, and the standby USB connections, wow! VERY NICE JOB showing the build and color connections, etc, excellent! THANK YOU!!!
Malheureusement c'est pas à la portée de la majorité pour avoir ce genre d'outils.. c'est merveilleux .. c'est un travail minutieux, esthétique et le résultat est une merveille.
Building the case seems to be the most involved part of the project. You clearly have all the tools and skills needed. I would love to see an overall shot of your workshop!
There's a German accent involved. You know it'll probably be better than factory. :))) After watching I have confirmed that I wasn't wrong. Probably the best ATX PSU conversion on the internet. Such attention to detail and safety is well integrated. +10
Got my ham radio license early this year during the virus mess. Since then I have really been enjoying building a radio go box, power distribution box, and a dc power supply. Yours looks very professional. Im OCD, but dont have the equipment you do to 3D print etc.
I love this modular concept. Simply excellent. Did you know that if you isolate (with simple rubber washers) the output side of the PSU from the case. You can connect 2 PSU's together. Why? To get 24V at much higher amperage than can be given by the blue wire (-12V). There is a video on how to do this, when I find it again I will edit this and show it. I dont know if it works with 3 or more PSU's. This will also give you considerably more voltages varying from any combination of 3.3, 5, and 12 up to 24 (i.e. 3.3+5 = 8.3, or 3.3+12 = 15.3 etc, all at higher amperages that the highest amperage of lowest amperage PSU can handle - which is significantly more than the blue wire and much more useful). The other reason I like it is because it is much easier to add additional features. Reverse polarity protection for example - which is needed if you want to charge car batteries. I'm going to build one like this. Thanks for sharing.
Awesome design and build! However, I would think the front bezel needs a port to provide air throughput since the fan in the power supply is drawing negative flow. Too much of a seal in the enclosure will burnout the fan in the power supply as well as creating too much heat from too little air flow thus reducing the life span of the power supply itself. But overall I love it!!
I am thinking that as little load that this PS will probably be under as a Bench PS will be minimal as opposed to being a functioning Computer PS. I think the fan should be fine. In fact, there will be a lot less worry about dust clogging up the fan since it will be primarily be blowing air OUT the fan opening. That would be my only concern. If the fan were blowing IN to the PS instead of OUT, then it might be a problem. Good point though.
Great project. Last week I found working ATX power supply on the street and I want to make an adjustable power supply. Your tutorial is the best one I have found :D thank you very much! Amazing work! I'm definitely going to subscribe
Very nice. this is the best-looking home-built power supply I have seen so far. excellently detailed instruction. This gives me an idea of how I am going to build my next project.
Definitely the best diy power supply with maximum attention to detail! Congratulations! Forgive my ignorance... will there be any problem in resorting to the -12V (blue cable you cut) as ground and +12V (yellow), and then we would have the 24V? So I avoid using an upsteper to convert 12V to 24V... Thank you in advance.
Very nice and good looking project. Also very glad you didn't use hot glue to mount any critical components and actually properly installed everything👍
Nice build, looks really good ! :) but PG is a signal, not a power rail - you must not use to power a step up converter (cheap PSU tie PG to 5V so no problem, but spec says it's a signal active high). for ATX you definitely don't need the load resistor on 5V rail - that was a thing for old AT power supplies.
Simple to do, so long as you happen to have the bits laying around. I'm sure most of us do. In the junk pile in the corner is where I keep my fully equipped workshop with router bench, table saw, 3D printer, etc. Simple things we all have at our disposal..........I really liked the finished product though, Looks really Hi-Tech with all the outputs and the OLED panel at the top. And I REALLY liked the terminal block inside, that made things really neat for a few minutes...before the front panel spaghetti made it's appearance.
A lot people that are actually building their own power supply have this stuff (I do). If you don't, you can use whatever plastic container you want and cut that with a box knife. The box is not the most important bit of this build.
Hi ! Very nice project and right my kind of thinking - thx for sharing ! I though think it seems a little old fashioned with these old-school fuse holders ;-) - how about adding a PLUG-IN MODULE for adjustable current limitor - just installable instead of the fuse holders - it would be a very nice addition to you project, I think.
One of the best videos for bench power supply i watched on youtube. Very detailed work to perfection. I would like to build one of this. Could you post links for the parts you used and if possible the stl files? Thank you in advance.
Nicely done. The only thing missing is a flow-thru vent in the face or side panels to allow air to circulate. Otherwise, the power supply is likely to run hot.
I like the way you roll. I plan on using your basic plans but will have to purchase a small plastic or metal case as I have no where to set up my table saw and I do not have a 3D printer.I have a power supply from an old Dell Optiplex 380 that I plan to use. This is one of the best power supply builds I have seen. I appreciate all the great suggestions you share on RUclips. I an an Amateur Radio operator and this will be very useful in my hobby. Robert KO4CER
Great project! One thing that I think you overlooked is the PSU ventilation. The fan being in either a push/pull configuration has no way of getting fresh air or exhausting air as it is in a closed box. Let me know if I am wrong
I love everything about this video! Your voice is very calming You explain every step with extreme detail It's relaxing to watch you go through all of that wood working And my favorite, the electronics!
If I can put this simply. I bloody love this! I’ve saved one of those power supply units for ages from and old desktop pc because I had an idea that it could be useful when I’m model making or just testing stuff. I haven’t made anything yet because I kept fumbling for ideas on how I’d like to do it so I just kept putting it off. Not any more. That sir is bloody awesome and I’m so happy I subscribed earlier. One of the most underrated channels on the tube in my opinion. Good health to you! 🍻
Excellent idea and design. Although I saw a detail that the source lacked, it has air outlet, but it does not have fresh air inlet, it lacks a grille for new air to enter. Excelente idea y diseño. Aunque vi un detalle que le faltó la fuente tiene salida de aire, pero no tiene entrada de aire fresco, le falta una rejilla para que entre aire nuevo.
I don't know how much it can cost, but you need to think about the economic sense of building such a power supply. Yes, on the 12V line from the power supply you can pull a nice current, but such a power supply should in my opinion be universal. I don't know how much an adjustable panel can cost, but if everything would cost about $ 25, it might be better to look at the outlets of Yihua 305D power supplies. If someone has an adjustable panel and an unused power supply, I see it makes sense. Otherwise, if we don't use 3.3V, 5V or 12V too often, it is better to buy the cheapest regulated 0-30V, 0-5A power supply. But let it not be. Instructional video nicely made. Thumb flies up. And the look. Despite this, it looks great. Best regards.
congratulations you have made a superb job of the build.and it looks a very beautiful finish.i wish that my carpentry skills were even as half as good as yours are. all the best my friend.
Not sure if the standby power can supply enough current for the the USB socket (some power supply are as low as 0.2A. Standby is meant to keep power going to a small set of components on the motherboard used to control the power-on signal from the motherboard back to the PSU when you want it to turn on (to allow for Wake on LAN). The USB socket is designed to take in 12V (not 5V), so you may be under-powering the circuitry in there as well. It is much safer to wire it to the 12V output of the PSU. You'd lose the always on ability, but you at least know you have enough voltage and current to power it.
Very nice project, impressive workmanship! I too do woodworking and electronics... There's a lot of good things on this project. I have a couple of questions about using those voltage step up modules: The 12V on the Power Good Signal, I'm surprised it worked as I would have expected it to be a logic signal and not have enough current to power the 12V step up... since you only want to power an LED, there's a dropper resistor in the switch, not that the LED itself needed 12V, so I'd just get the right pushbutton/LED... LEDs only take a few milliamps and the step up supply takes a lot more... but luckily it seems to work and who can argue with success? Secondly, the 24V step up for the variable supply output: Does it have enough current for the things you want to power? The 12V is boost then the variable supply is a buck so... does it have enough oomph after stepping up and down? Lastly, you didn't mention the need for the load resistor... I assume that it was necessary for the supply so it wouldn't run away open circuit?? Seems wasteful too bad you couldn't find an interesting way to use that energy instead of turning it into heat... Anyway, I just found your channel, subscribed, and thumbs up! Good Job! I will explore more in your videos.
Beautiful build, I have one question, the PSU is pulling the heat out the back of the enclosure but the intake is on the inside blocked with no vents, does this not put the fan under more static pressure and increase the operating temperature?
Hello.... I would like to start off by saying that i absolutely love watching your videos. I have learned quite a bit just by watching them and listening to you talking and guiding us step by step through the project at hand. To be quite honest, i subscribed just after watching my very first vídeo on your RUclips channel. The Bench Power Supply. I myself am just now starting out building small DIY projects. Which brings me to ask you. Would you please be willing to build a case like the one in the video along with all of its accessories and 3D Prints necessary to build a power supply like yours and sell it to me? If so, how much would it cost? Plus shipping it to me in Portugal? I know it is kind of far. But luckily still in the EU. 😏 I know that this might sound a bit awkward. But please let me explain. I only ask this of you mainly, because of your professionalism and expertice. But also because of my health issues, i have absolutely no way of being able to build one myself. You see, i have cronic kidney disease/failure. And i am currently doing three, four hour, weekly sessions of hemodialysis. And have been for the past eight years. Because of this i have a prosthesis implanted in each arm which leave me with barely any strength in them. Thus the reason that i can only do small mainly electronic based projects. Just one final note. And if it is not too much trouble. Would it be possible for you to please send me or put the parts list of the components that you used to build the power supply? Thank you ever so much for your attention. And keep up the great work on making such amazing videos and projects. You can rest assured that i will definately be watching them. God Bless.
Very nice job, I will be using your wiring diagram. Unfortunately I dont have access to a table saw or a 3d printer so my build will have a different case. One question,. When the fan on the ATX power supply is blowing out air where is it "sucking" the air from. I did not see an air inlet anywhere on your case.
What a very neat and tidy job! You have made a nice unit. I have several ATX Power supplies in cases of old computers I can't bring myself to throw away, so here's a productive way to use one of them at least. Thank you! Nice job.
Looks fantastic and that is a very handy thing to have. I have little understanding of electronics - can you please kindly explain me the resistor - why do you need it and what is it's function
found this in my recommendation as I was looking at PSU's/electronic repair but once I saw the woodworking equipment and the DIY sled w/stop block, push sticks, saw blades holder and even a DIY digital height gauge I hit Subscribe/like right away, look forward to checking out what else you have made.
Excellent detailed work! But I have a question. I believe the dc boost converter you are using cannot handle much amperes. Maybe 2-3. On the other hand the variable dc converter with the screen you are using is for more amperes. Perhaps 5A. ( I know that because I hane one too) . So you cannot use its full potential. Why didn't you connect 12v from the ATX to that final dc to dc converter?
Nice one! I just built one my self with components I had (from about 10-20 years ago :-) with 15 year old PSU. I did the easy way though and drilled my PSU case and connected everything. It was a really tight fit though as my PSU fan was "silent" and covered the whole top of the PSU. I do think I will add the buck/boost and as you did though to get the digital volt/current meter with PSU as that would make it almost perfect!
Excellent case design! I had planned on converting a couple of old ATX power supplies for a number of years now. I am printing out your design right now, I can finally have the finished look I wanted to go for, thank you. I know you have since upgraded your original design, but with the original, you could eliminate the step-up converter for the 12V lighted switch by using one of the power supplies yellow 12V power leads. Thus eliminating the PG connection unless wanting to use it for LED indication or some other 5V connection. The original switch needs 12V for the power indicator light, not for switching.
Very nice ! Thanks for sharing this. Can I use all outputs (var, 12v, 5v, 3.3v) simultaneously? Or at least the var one and any other one? I have read below that it can be risky.
Outstanding work!!! You sir are a perfectionist!! Thank you for posting this. This is the best ATX power supply build I have seen so far, albeit with a lot more work involved. Be proud of what you have accomplished. Subscribed!!
Fantastic woodworking project! Is the sanding pad holder a DIY project or store bought? These power supplies can be obtained from appliance stores that take in old computers for next to nothing. Just don’t return the old computer in a million pieces. We extract what we need and then reassemble the cases and return them to their recycling storage. Anyone know the value of the "keep alive resistor"? It appears to be a 10 to 20 watt wire wound but the ohms? Excellent use of custom printed panels and supports, makes for a neat assembly. Even the short height desktop computer housings make excellent cabinets, although a bit deep. For those who are into amature radio, these desktop housings are perfect for making a repeater. ICOM and KENWOOD radios fit perfectly within the width of the drive bays with everything else placed within the cabinet. Next project is a similar bench supply for me. Tired fiddling with multiple supplies to get projects up and running!
Very nicely done! One thing I might do differently concerns supplying more power to the USB socket. The one used is designed for Quick Charge 3.0... It clearly will not be able to do that if all you give it is 5 volts... So, I would use a yellow (12V) wire instead of the 5 volt STB wire. If having a true 5 volt USB output that continues to work when the main switch is off is still important, you can always install another, simpler socket. But to me, spending that much on this particular socket and not using it to its full potential seems like a waste. ;-) Again, great build! Cheers from Canada!
Hello, very great job !! Can you send me the plans and more description (like how is the value of each fuse..) because your website is unavailable. Thank you.
Nice video. I am planning to build a power supply so your video is just in time! Would you be inclined to publish a parts list? I would appreciate it very much. I look forward to more videos.
Just a thought... PG pin can probaby dispatch enough current to run a small relay, so you can power a switch LED from the 12v rail. No need for this boost converter. And about fuses on 12, 5 & 3.3V rails... Got myself some resettable automotive fuses. Clumsy bastard, as i am, i went through ordinary fuses like they had expiration date coming up :D
This guy here seems to be more of a good carpenter than an electronics guy. I use enclosures from salvaged devices and save myself the effort of building one from scratch. I’d rather put that effort into the electronics.
That's a great project minus the total lack of cooling airflow :/ Hope you add some front bottom intake holes at least, that PSU is already restricted by the sheet metal chassis and plastic holders.
Awesome, how I wish to have those tools and the 3d printer, but overall your skills in step by step creative order, great job and congrats from Mexico City
honestly most of the stuff is actually rather easy to build manually. Replace parts with acrylic and MDF/Plyboard wherever necessary and well, it's rather simple. Just some hard work.
Brilliant DIY!! I have a question for you, hope you will help me with some clarity: I'm using a 450W computer power supply to power my LiPo charger, but the 12V rail drops to 11.5V when drawing just 2.3A, even though it's rated for 34A. I measured this voltage at the PCB level itself, so it seems the power supply itself is the issue, not the single thin yellow wire I am using to draw power. Any idea why the voltage drops like this? Also, is the dummy load resistor necessary for stable voltage output on the 12V rail? I have seen everyone using it, but never understood its role. I am not using any dummy load resistor.
Very nicely done! Does the variable supply portion have Constant Current capability as well? All ATX supplies lack this feature but CC can save you from accidentally frying the circuits you're working on which is why it is almost always included in lab power supplies. Also, while it is a good idea to mount the power resistor to the metal case as the metal will act as a heatsink, I would mount it using screws rather than hot glue to prevent the resistor from softening the glue while in use. A dab of heatsink compound will also aid the heat transfer into the case.
Yes the custom module frontend has CC ability. He fed it with a very very weak boost regulator in the video though, so it cannot use 90% of the PSU capability.
Very clean build. I have one question though: Why did you use a step up converter only to power the switch LED when you could power it directly from the 12V output? Considering the low current needed, I don't understand it.
please tell me what size (amp) fuses you used on your Benchtop power supply, all 4 fuses, (x3 to the posts and x1 to the 24 volt step up convertor). It was an excellent build, with good detailed explanation, I love your precision, thanks for sharing.
Nice Build which I want to reproduce; HOWEVER, what are Hauptschalter, Widerstand, Aufwärtswandler, Spannungswandler, they sound German but might just be Danish (without frosting); the last one I can assume are resistors; Bannanenkeplung should be (Banana plugs or couplings). I do the English very well although I am in a Spanish speaking country, your help will be greatly appreciated, again Nice Work!!
Looks awesome. Why measure the voltage of fixed voltage outputs? Current meters would have been more useful. The standby output of a typical ATX PSU can only supply 1amp, not ideal seeing as your USB outlets are rated for 2.7A each.
Nice project, but I think the little tiny step up converter is way´s to small. It looks like a 1A version and not more that 10W. The step down converter with display can up to 5 or more amp.
Amazing and well done. We live in a remarkable time where so many of these components are readily available and affordable.
for viewers: before cutting the molinex connector look for any pin with an additional (usually thinner) wire, and for the orange or brown wire in pin 11/20 or 13/24, these are 'sense' wires and must be connected so that the power supply knows it's working or else it shuts down immediately. Also google the model of your power supply for minimum load(s), some only need 1 amp load on the 5v line, some need 0.5amp on the 3.3v, 5v, AND the 12v lines. The variable stepdown output unit needs a diode on the output to protect against feedback if you use if for battery charging or anything with capacitence/inductance such as a motor. I might also suggest circuit breakers instead of fuses for the 3.3,5,12v lines.

Came for the power supply and electronic tutorial. He got to the table saw with home made slead for his cuts for his case and I hit subscribe.
Me too
well i do love his highly skilled workmanship.
A couple points from an electronic engineer of over 50years skills.
1. I would recommend not having air in and air out on back panel, unless there is some form of horizontal separation barrier sticking back at least 200mm from one side to the other.
I note as other have pointed out there are grills on the back panel situated above the fan outlet grill.
Now if unit is placed with back near a wall or rear of bench with a high back the air will start to recirculate and unit will get hot.
His case is beautifully designed and made, except for this critical thermal flaw.
Look at any type of commercial equipment and you will never see inlet and exhaust placed adjacent to each other.
Further like the desk top computers these supplies are filled to, I would suggest adding a removable filter on any inlet air vent as a major killer of these supplies is both dust (causes electrical arcing in the High voltage DC section of the supply) and overheating.
2nd personally I would have painted the inside of the case with a fire resistant paint or lined it with a thin fire resistant material. But that's me, very safety conscious.
Absolutely brilliant video.
I will do say you have taught me a lot about building in timber.
Plus you mentioned some sort of cad software I had not heard of, that I will look up as I have recently got myself a 3D printer.
Also EXCELLENT graphic schematic showing how to wire unit. I have to ask what did you draw that in please?
INCREDIBLE Workmanship. May I offer ONE suggestion?
Instead of cutting ALL of the wires from the Power Supply, get a Power Supply MOLEX connector from a defective motherboard, and solder all your wires to it.
Then you can just use the standard Power Supply output plug to attach to your wiring harness. Someday your Power Supply will FAIL. So when it does, you can simply UNPLUG it and replace it with another in just a few minutes.
I was going to say the same thing. Thats the way I made mine.
That's a good idea. I'll implement this.
An even easier way is you can buy a board of ebay for about $10 that has the molex connector, banana sockets for all voltages, already fused and has an LED and on/off switch. Just plug it in and you're ready to rock'n'roll.
there used to be 24-20 pin converters for using a new power supply with a 20-pin motherboard, on those, wires are already in, so maybe that will be even easier? something like this: www.cableleader.com/6-atx-20-pin-female-to-24-pin-male-motherboard-adapter-cable.html

Excellent build. I had a bench top supply that I made when I first started with Arduinos. I found that for many projects I needed more than 12 volts, but I rarely needed more than two voltage inputs simultaneously. To keep the footprint small I made mine with two variable outputs using the same modules you used. I made it so I can use a power supply from a laptop or any other type of supply using the same size male jack. The main power supply sits on the floor out of the work area and only the variable control and outputs are on the bench top. Adding multiple female jacks makes it possible to use any supply I happen to have available whether it has a barrel jack like my old Toshiba laptop or a rectangular one like my wife’s Lenovo. I can also use the power supply for my 3D printer or even my model railroad. It is very inexpensive if you shop carefully for the components.
I would love to see a picture of your build!
This is the nicest power supply project I have seen. There are many on RUclips, but the quality and finish on this one is exceptional.
Finally, someone designed it the way I was working towards .... last ???. All 3 separate standard voltages, adjustable up to 24v, and the standby USB connections, wow! VERY NICE JOB showing the build and color connections, etc, excellent! THANK YOU!!!
I love your attention to detail. Must have giving you great pride and personal gratification to see such a project completed. Excellent work.
That case itself is a work of art, and the rounded edges and color make it look retro!
Malheureusement c'est pas à la portée de la majorité pour avoir ce genre d'outils.. c'est merveilleux .. c'est un travail minutieux, esthétique et le résultat est une merveille.
Building the case seems to be the most involved part of the project. You clearly have all the tools and skills needed. I would love to see an overall shot of your workshop!
The hand holds in your crosscut sled are genius!
Thank you.
I agree, good idea!
You know what they say about people like you? WOW!!! I'm in awe. You're extremely talented. :) Thanks for sharing
There's a German accent involved. You know it'll probably be better than factory. :)))
After watching I have confirmed that I wasn't wrong. Probably the best ATX PSU conversion on the internet. Such attention to detail and safety is well integrated. +10
This is the best ATX to benchtop power supply ever! very well done. Clean and simple.
Your not only an electronic genius your wood working skills are next level as well.
Got my ham radio license early this year during the virus mess. Since then I have really been enjoying building a radio go box, power distribution box, and a dc power supply. Yours looks very professional. Im OCD, but dont have the equipment you do to 3D print etc.
17:34 wiring dia. Great build, thank you for showing your work.
ruclips.net/channel/UC1zfaGMjbhfpfOi--atjD-g Passa da qui!
I wish I can cut MDF that clean and without gaps.
Great workmanship.
I love this modular concept. Simply excellent. Did you know that if you isolate (with simple rubber washers) the output side of the PSU from the case. You can connect 2 PSU's together. Why? To get 24V at much higher amperage than can be given by the blue wire (-12V). There is a video on how to do this, when I find it again I will edit this and show it. I dont know if it works with 3 or more PSU's. This will also give you considerably more voltages varying from any combination of 3.3, 5, and 12 up to 24 (i.e. 3.3+5 = 8.3, or 3.3+12 = 15.3 etc, all at higher amperages that the highest amperage of lowest amperage PSU can handle - which is significantly more than the blue wire and much more useful).
The other reason I like it is because it is much easier to add additional features. Reverse polarity protection for example - which is needed if you want to charge car batteries. I'm going to build one like this. Thanks for sharing.
Awesome design and build! However, I would think the front bezel needs a port to provide air throughput since the fan in the power supply is drawing negative flow. Too much of a seal in the enclosure will burnout the fan in the power supply as well as creating too much heat from too little air flow thus reducing the life span of the power supply itself. But overall I love it!!
I am thinking that as little load that this PS will probably be under as a Bench PS will be minimal as opposed to being a functioning Computer PS. I think the fan should be fine. In fact, there will be a lot less worry about dust clogging up the fan since it will be primarily be blowing air OUT the fan opening. That would be my only concern. If the fan were blowing IN to the PS instead of OUT, then it might be a problem. Good point though.
Great project. Last week I found working ATX power supply on the street and I want to make an adjustable power supply. Your tutorial is the best one I have found :D thank you very much! Amazing work! I'm definitely going to subscribe
The Part list of the Power Supply is now in the Video Description.
Your attention to detail is amazing. This is one of the best videos I've seen.
I was sort of thinking...."hey, I can do this"....until 15:20! Thanks for posting. I don't have a 3-D printer, but it offered a lot of good ideas.
Very nice. this is the best-looking home-built power supply I have seen so far. excellently detailed instruction. This gives me an idea of how I am going to build my next project.
Definitely the best diy power supply with maximum attention to detail! Congratulations! Forgive my ignorance... will there be any problem in resorting to the -12V (blue cable you cut) as ground and +12V (yellow), and then we would have the 24V? So I avoid using an upsteper to convert 12V to 24V... Thank you in advance.
The maximum current for converter 1A i think will born with load
Very nice and good looking project. Also very glad you didn't use hot glue to mount any critical components and actually properly installed everything👍
Nice build, looks really good ! :) but PG is a signal, not a power rail - you must not use to power a step up converter (cheap PSU tie PG to 5V so no problem, but spec says it's a signal active high). for ATX you definitely don't need the load resistor on 5V rail - that was a thing for old AT power supplies.
Simple to do, so long as you happen to have the bits laying around. I'm sure most of us do. In the junk pile in the corner is where I keep my fully equipped workshop with router bench, table saw, 3D printer, etc. Simple things we all have at our disposal..........I really liked the finished product though, Looks really Hi-Tech with all the outputs and the OLED panel at the top. And I REALLY liked the terminal block inside, that made things really neat for a few minutes...before the front panel spaghetti made it's appearance.
A lot people that are actually building their own power supply have this stuff (I do). If you don't, you can use whatever plastic container you want and cut that with a box knife. The box is not the most important bit of this build.
You are a true craftsman sir! Thank you for such an intimate, detailed presentation.
Hi !
Very nice project and right my kind of thinking - thx for sharing !
I though think it seems a little old fashioned with these old-school fuse holders ;-) - how about adding a PLUG-IN MODULE for adjustable current limitor - just installable instead of the fuse holders - it would be a very nice addition to you project, I think.
One of the best videos for bench power supply i watched on youtube. Very detailed work to perfection. I would like to build one of this. Could you post links for the parts you used and if possible the stl files? Thank you in advance.
Nicely done. The only thing missing is a flow-thru vent in the face or side panels to allow air to circulate. Otherwise, the power supply is likely to run hot.
I like the way you roll. I plan on using your basic plans but will have to purchase a small plastic or metal case as I have no where to set up my table saw and I do not have a 3D printer.I have a power supply from an old Dell Optiplex 380 that I plan to use. This is one of the best power supply builds I have seen. I appreciate all the great suggestions you share on RUclips. I an an Amateur Radio operator and this will be very useful in my hobby. Robert KO4CER
Great project! One thing that I think you overlooked is the PSU ventilation. The fan being in either a push/pull configuration has no way of getting fresh air or exhausting air as it is in a closed box. Let me know if I am wrong
Wow ! I'm very impressed by your skills ! A professional workshop on the side may also help to "simply" built this project to perfection.
That has to be the nicest looking D.I.Y. Power supply from an ATX PSU. Thank you!
I love everything about this video!
Your voice is very calming
You explain every step with extreme detail
It's relaxing to watch you go through all of that wood working
And my favorite, the electronics!
If I can put this simply.
I bloody love this!
I’ve saved one of those power supply units for ages from and old desktop pc because I had an idea that it could be useful when I’m model making or just testing stuff. I haven’t made anything yet because I kept fumbling for ideas on how I’d like to do it so I just kept putting it off. Not any more. That sir is bloody awesome and I’m so happy I subscribed earlier.
One of the most underrated channels on the tube in my opinion.
Good health to you! 🍻
I love it wish I would known about this a few years back when I threw my old computer out. Thanks
I came for the power supply but loved the wood working saw slide....then the final product. 😊
this build is deff on my bucket list!
Excellent idea and design. Although I saw a detail that the source lacked, it has air outlet, but it does not have fresh air inlet, it lacks a grille for new air to enter. Excelente idea y diseño. Aunque vi un detalle que le faltó la fuente tiene salida de aire, pero no tiene entrada de aire fresco, le falta una rejilla para que entre aire nuevo.
Of course is there a air inlet. the inlet is in the upper back area and the outlet is in the lower area.
I don't know how much it can cost, but you need to think about the economic sense of building such a power supply. Yes, on the 12V line from the power supply you can pull a nice current, but such a power supply should in my opinion be universal. I don't know how much an adjustable panel can cost, but if everything would cost about $ 25, it might be better to look at the outlets of Yihua 305D power supplies. If someone has an adjustable panel and an unused power supply, I see it makes sense. Otherwise, if we don't use 3.3V, 5V or 12V too often, it is better to buy the cheapest regulated 0-30V, 0-5A power supply.
But let it not be. Instructional video nicely made. Thumb flies up.
And the look. Despite this, it looks great.
Best regards.
You must be a perfectionist. Thumbs up to you.
congratulations you have made a superb job of the build.and it looks a very beautiful finish.i wish that my carpentry skills were even as half as good as yours are. all the best my friend.
Supremely overbuilt. But someone has to show us how high the build quality can go.
Many thanks!!
Mostly, How I made a BOX with all these tools.
Good content BTW.
Not sure if the standby power can supply enough current for the the USB socket (some power supply are as low as 0.2A. Standby is meant to keep power going to a small set of components on the motherboard used to control the power-on signal from the motherboard back to the PSU when you want it to turn on (to allow for Wake on LAN). The USB socket is designed to take in 12V (not 5V), so you may be under-powering the circuitry in there as well. It is much safer to wire it to the 12V output of the PSU. You'd lose the always on ability, but you at least know you have enough voltage and current to power it.
upvote for the ultra clean wiring
how come you only have 43k subscribers? your content is amazing!
Would you mind listing dimensions of the box and possibly the srt files used for the 3d printed parts? Excellent job it looks great.
Very nice project, impressive workmanship! I too do woodworking and electronics... There's a lot of good things on this project. I have a couple of questions about using those voltage step up modules: The 12V on the Power Good Signal, I'm surprised it worked as I would have expected it to be a logic signal and not have enough current to power the 12V step up... since you only want to power an LED, there's a dropper resistor in the switch, not that the LED itself needed 12V, so I'd just get the right pushbutton/LED... LEDs only take a few milliamps and the step up supply takes a lot more... but luckily it seems to work and who can argue with success? Secondly, the 24V step up for the variable supply output: Does it have enough current for the things you want to power? The 12V is boost then the variable supply is a buck so... does it have enough oomph after stepping up and down? Lastly, you didn't mention the need for the load resistor... I assume that it was necessary for the supply so it wouldn't run away open circuit?? Seems wasteful too bad you couldn't find an interesting way to use that energy instead of turning it into heat... Anyway, I just found your channel, subscribed, and thumbs up! Good Job! I will explore more in your videos.
Beautiful build, I have one question, the PSU is pulling the heat out the back of the enclosure but the intake is on the inside blocked with no vents, does this not put the fan under more static pressure and increase the operating temperature?
Hello....
I would like to start off by saying that i absolutely love watching your videos. I have learned quite a bit just by watching them and listening to you talking and guiding us step by step through the project at hand.
To be quite honest, i subscribed just after watching my very first vídeo on your RUclips channel. The Bench Power Supply.
I myself am just now starting out building small DIY projects.
Which brings me to ask you. Would you please be willing to build a case like the one in the video along with all of its accessories and 3D Prints necessary to build a power supply like yours and sell it to me? If so, how much would it cost? Plus shipping it to me in Portugal? I know it is kind of far. But luckily still in the EU. 😏
I know that this might sound a bit awkward. But please let me explain.
I only ask this of you mainly, because of your professionalism and expertice. But also because of my health issues, i have absolutely no way of being able to build one myself.
You see, i have cronic kidney disease/failure. And i am currently doing three, four hour, weekly sessions of hemodialysis. And have been for the past eight years. Because of this i have a prosthesis implanted in each arm which leave me with barely any strength in them. Thus the reason that i can only do small mainly electronic based projects.
Just one final note. And if it is not too much trouble. Would it be possible for you to please send me or put the parts list of the components that you used to build the power supply?
Thank you ever so much for your attention. And keep up the great work on making such amazing videos and projects. You can rest assured that i will definately be watching them.
God Bless.
Wow! Such a great build. Love your attention to detail and craftsmanship! Inspiring! Thanks!
Very nice job, I will be using your wiring diagram. Unfortunately I dont have access to a table saw or a 3d printer so my build will have a different case.
One question,. When the fan on the ATX power supply is blowing out air where is it "sucking" the air from. I did not see an air inlet anywhere on your case.
No air intake.
It will overheat sooner rather than later.
The back panel has an open grid, above the ATX power supply. See 12:48
What a very neat and tidy job! You have made a nice unit. I have several ATX Power supplies in cases of old computers I can't bring myself to throw away, so here's a productive way to use one of them at least. Thank you! Nice job.
Looks fantastic and that is a very handy thing to have. I have little understanding of electronics - can you please kindly explain me the resistor - why do you need it and what is it's function
Many psu will not turn on unless they sense a load so the resistor makes a load for it to see.
found this in my recommendation as I was looking at PSU's/electronic repair but once I saw the woodworking equipment and the DIY sled w/stop block, push sticks, saw blades holder and even a DIY digital height gauge I hit Subscribe/like right away, look forward to checking out what else you have made.
Same...
Excellent detailed work! But I have a question. I believe the dc boost converter you are using cannot handle much amperes. Maybe 2-3. On the other hand the variable dc converter with the screen you are using is for more amperes. Perhaps 5A. ( I know that because I hane one too) . So you cannot use its full potential. Why didn't you connect 12v from the ATX to that final dc to dc converter?
Nice one! I just built one my self with components I had (from about 10-20 years ago :-) with 15 year old PSU. I did the easy way though and drilled my PSU case and connected everything. It was a really tight fit though as my PSU fan was "silent" and covered the whole top of the PSU.
I do think I will add the buck/boost and as you did though to get the digital volt/current meter with PSU as that would make it almost perfect!
Excellent case design! I had planned on converting a couple of old ATX power supplies for a number of years now. I am printing out your design right now, I can finally have the finished look I wanted to go for, thank you. I know you have since upgraded your original design, but with the original, you could eliminate the step-up converter for the 12V lighted switch by using one of the power supplies yellow 12V power leads. Thus eliminating the PG connection unless wanting to use it for LED indication or some other 5V connection. The original switch needs 12V for the power indicator light, not for switching.
Nice. Only dif I'd make is put a label for the voltages and use those displays for the current.
Very nice ! Thanks for sharing this. Can I use all outputs (var, 12v, 5v, 3.3v) simultaneously? Or at least the var one and any other one? I have read below that it can be risky.
Fantastic clean and perfect handmade project
The video is very informative and the whole construction is professional. John from Greece.
ruclips.net/channel/UC1zfaGMjbhfpfOi--atjD-g Passa da qui!
Outstanding work!!! You sir are a perfectionist!! Thank you for posting this. This is the best ATX power supply build I have seen so far, albeit with a lot more work involved. Be proud of what you have accomplished. Subscribed!!
A work of art and such detail, well done!
Fantastic woodworking project! Is the sanding pad holder a DIY project or store bought? These power supplies can be obtained from appliance stores that take in old computers for next to nothing. Just don’t return the old computer in a million pieces. We extract what we need and then reassemble the cases and return them to their recycling storage. Anyone know the value of the "keep alive resistor"? It appears to be a 10 to 20 watt wire wound but the ohms?
Excellent use of custom printed panels and supports, makes for a neat assembly. Even the short height desktop computer housings make excellent cabinets, although a bit deep. For those who are into amature radio, these desktop housings are perfect for making a repeater. ICOM and KENWOOD radios fit perfectly within the width of the drive bays with everything else placed within the cabinet.
Next project is a similar bench supply for me. Tired fiddling with multiple supplies to get projects up and running!
Sir you created awesome thing... You are a great experienced man
Very nicely done!
One thing I might do differently concerns supplying more power to the USB socket. The one used is designed for Quick Charge 3.0... It clearly will not be able to do that if all you give it is 5 volts... So, I would use a yellow (12V) wire instead of the 5 volt STB wire. If having a true 5 volt USB output that continues to work when the main switch is off is still important, you can always install another, simpler socket. But to me, spending that much on this particular socket and not using it to its full potential seems like a waste. ;-)
Again, great build!
Cheers from Canada!
Hello, very great job !! Can you send me the plans and more description (like how is the value of each fuse..) because your website is unavailable. Thank you.
Nice video. I am planning to build a power supply so your video is just in time! Would you be inclined to publish a parts list? I would appreciate it very much. I look forward to more videos.
Just a thought... PG pin can probaby dispatch enough current to run a small relay, so you can power a switch LED from the 12v rail. No need for this boost converter. And about fuses on 12, 5 & 3.3V rails... Got myself some resettable automotive fuses. Clumsy bastard, as i am, i went through ordinary fuses like they had expiration date coming up :D
What a nice, clean and beautifull work. Best I've ever seen.
Congrats
Really fantastic work, dude! It really looks beautiful! 😃
This guy here seems to be more of a good carpenter than an electronics guy. I use enclosures from salvaged devices and save myself the effort of building one from scratch. I’d rather put that effort into the electronics.
That's a great project minus the total lack of cooling airflow :/ Hope you add some front bottom intake holes at least, that PSU is already restricted by the sheet metal chassis and plastic holders.
old world German craftsmanship
Swiss craftsmanship ;-)
Awesome, how I wish to have those tools and the 3d printer, but overall your skills in step by step creative order, great job and congrats from Mexico City
honestly most of the stuff is actually rather easy to build manually. Replace parts with acrylic and MDF/Plyboard wherever necessary and well, it's rather simple. Just some hard work.
Brilliant DIY!! I have a question for you, hope you will help me with some clarity: I'm using a 450W computer power supply to power my LiPo charger, but the 12V rail drops to 11.5V when drawing just 2.3A, even though it's rated for 34A. I measured this voltage at the PCB level itself, so it seems the power supply itself is the issue, not the single thin yellow wire I am using to draw power. Any idea why the voltage drops like this? Also, is the dummy load resistor necessary for stable voltage output on the 12V rail? I have seen everyone using it, but never understood its role. I am not using any dummy load resistor.
I'd include + and -12V or + and - 15V for operational amplifiers, too, but I suppose it's easy to add on with step up converters.
Very nicely done! Does the variable supply portion have Constant Current capability as well? All ATX supplies lack this feature but CC can save you from accidentally frying the circuits you're working on which is why it is almost always included in lab power supplies. Also, while it is a good idea to mount the power resistor to the metal case as the metal will act as a heatsink, I would mount it using screws rather than hot glue to prevent the resistor from softening the glue while in use. A dab of heatsink compound will also aid the heat transfer into the case.
Yes the custom module frontend has CC ability. He fed it with a very very weak boost regulator in the video though, so it cannot use 90% of the PSU capability.
Very clean build. I have one question though: Why did you use a step up converter only to power the switch LED when you could power it directly from the 12V output? Considering the low current needed, I don't understand it.
please tell me what size (amp) fuses you used on your Benchtop power supply, all 4 fuses, (x3 to the posts and x1 to the 24 volt step up convertor). It was an excellent build, with good detailed explanation, I love your precision, thanks for sharing.
Jack of all trades... Nice work.
Start here: 10:50 (don't search or wait)
Beautiful Project nice build. Love the design and detail.
you do very nice work I would like to build this it looks amazing although I really don't know what I would use it for keep up the great work
Easy, simple and detailed work
Nice Build which I want to reproduce; HOWEVER, what are Hauptschalter, Widerstand, Aufwärtswandler, Spannungswandler, they sound German but might just be Danish (without frosting); the last one I can assume are resistors; Bannanenkeplung should be (Banana plugs or couplings). I do the English very well although I am in a Spanish speaking country, your help will be greatly appreciated, again Nice Work!!
Looks awesome. Why measure the voltage of fixed voltage outputs? Current meters would have been more useful. The standby output of a typical ATX PSU can only supply 1amp, not ideal seeing as your USB outlets are rated for 2.7A each.
Wow really detailed work...I really like the wiring diagram...it really helps me understanding it this way
Excellent Sir your all work was outstanding it is very useful power supply in work shop.
Nice project, but I think the little tiny step up converter is way´s to small. It looks like a 1A version and not more that 10W. The step down converter with display can up to 5 or more amp.
