The best video I have seen as of yet explaining properly all of the functions of all of the color coding wires. Thanks for a good explanation.
Guys I really need help with this project, so I started building it from scratch, got me a good 500W power supply unit from the used computers store, I think it was really cheap.
I disassembled it, cut the wires as the video shows to work with them easily... and got the other parts from the electronics store, the thing is... I was trying to do the first holes with the hand drill but my cat just keeps standing there, staring and judging every movement I make, it won't pass... I have tried everything... from food to scratches and it won't move from the project table... I'm stuck at this, you guys can help me pleaseeee? I'm desperate to finish this power supply, but my cat won't PASSSS! HELP!
cat.exe has crashed, restart cat.exe
You should Always let the CAT pass...LOL...thanks MAN

same here, I nearly choked on my beer when he said that. Fantastic.
i want to charge my car bettery with computer power suply. But in power suply there is a yellow color wire having voltage is 12v thats ok,,, but ampere is low as about 1ampere to 2ampere only (which is not suffient to charge my car bettery). My problem is that how to increase the amperage of (yellow 12v wire) so that it charge my bettery easily.
regds,
thanks. plz reply in detail to solve my problem

Now I can't cut that hole!!!
So my project will fail if i don't let the cat pass?

Suggestions: USB signal , Short USB D+ and D-- Signal , It will increase the charge current when you charge your phone.
how about using USB-C connector on a fast charger?
What will be the power consumption, if we only use one 12V supply from PSU?
Will it be same as using it completely?
This is by far the best looking ATX PSU conversion I've ever seen. Well done my dude.
Since the rotary selector switch is merely there to select the input of the Volt/Amp meter, and you still retain power on 3.3/5/12V rails regardless of the switch's position (which is very useful FYI), I geuss I do have the "same level of genius", though, not in the bad light you painted it.
You however, neither seem to know why that would be useful, nor that it is an inherent trait of an ATX switching PSU. Assuming you know what the "switching" part of the description entails.
If you are going to leave salty comments, make sure you understand the topic beforehand. Unless it is you're goal to look like a fool. If it was, - success!
Also, this was a 7 month old comment.
Oh, and please work on your grammar, I almost had a stroke trying to read your comment. English is not my primary language either, so that's no excuse...
@Jilvir Paeste apparently you suck at both.
I hace a doubt, it seems that my source atx doesn't have the fuse included, if I wanted to add it, where should I put it? Will be right if I connect it in series with my switch of stand by or where? If anyone can help me I'll be so thankful.

really cool finish, you made me think to rebuild my lab psu made with ATX as well. I used 2 to get 24 V, and added a regulation circuit for regulated output ( max 2A) .
Did you just make two supplies and then run them in series?
Why not use a boost/buck converter to 2/3 12v wires and use that
@@voyagertechnologies ..buck/boost makes things worst if u consider limited noise tolerance ..you can calculate the tolerances hit in every circuit you connected ones..
@@jhonnyginting8985 Seriously you gonna complain about noice when the guys alternative is connecting 2 psu's in series! Ever used an old psu, he certainly aint buying bequeit gold rated supply
FYI, Current regulation is quite easy if the voltage is fixed. All you need is a power transistor and a single low current resistor(and a spec sheet to learn the gain of the transistor) :P
Thumbs up for the 'cat pass' 😆! Informational video!
I love how you let the cat pass
You just gave me a super awesome idea sir.
Why run all 4 12 volt connections to one plug? Just make 4 12 volt terminals (+ and - pairs), 4 5volt terminals (+ and - )and 5 3.3 volt terminals (+ and - )and 1 heavy duty 12 volt terminal (+ and - ) with amperage control for my electroplating.
Sounds like it needs a big case right? You are correct in that thinking. I am just going to re use the old pc case that the power supply came in and repaint it a nice metallic finish to make it look all sciencey.
I might even put voltage readouts on each receptacle paring if there is enough room for 16 readouts. That is a dream lab setup on a stock Dell 550 watt power supply. :D
You need to connect "DATA -" and "DATA +" pins in USB port to start charging smartphone with higher current.
Ai de plm, un roman 😂 acel "Sorin" la inceput te-a dat de gol. Respect! Also a great video, very informative and well structured!
This video gives me some ideas. I must consider them. I have a few old but working power supplies that I have no current use for (for older computers) but I know a purpose I could use them for if I can get out the 12V and 5V. Thank you.
You must test its meter because the amperage is wrong.

So the cat pass was necessary to activate this power supply :-D
THATS FRICKIN RIGHT
It is necessary exorcism rite to shun out fault demons.
Perfect! Had a little jolt of education there. First time seeing the current reading independent from the voltage source.. could have broken some misconceptions fast when I was in school.. So you have to just be alert of the max current ratings.. the problem might be that you wouldn't be able to tell what you are doing to a single rail when you are using more than one at a time.. but I agree with the practical boundaries.. I would also not likely need more than that.
The -12v line can be combined with the +12v line to give you a 24v output. YMMV on if this will kill the power supply after a time, though.
Or a symmetric power supply unit. -12 / 0 / +12

I agree!!
Same here! I subscribed once the cat had passed! Lovely clear instructions and explanation as to WHY you did things a certain way. I now plan to make my own from an old PC PSU.... now to find an old PC PSU... :D
dont forget to find a cat
Hey great work! I'm about to make one too! BUT I want to be able to adjust amps too,not only volts. I mean, getting 12v with 0,5A, and 12v with 1A or 2A or 1,87A. Any ideas for that? except from buying a regulator...
hi. I don't think you can do that just from the PSU circuit board. you still need to add a converter with variable voltage and current.
I really like this - as it puts everything into the ATX enclosure. Most add an additional enclosure, which I haven't thought were necessary. However, I have the same comment I have with other electronic projects I've watched...
Buy a heat-gun! I watch people using a match or a lighter to shrink heat-shrink tubing, and it is so ineffective and so inaccurate (and possibly dangerous). In the US you can buy a heat gun for ~$10. This will make your projects much easier and can be used for many other purposes in your projects.
Nicely done Sorin. You have given me many good ideas for my next ATX conversion project: the rotary switch and volt/amp meter. Very good-looking finished product you can be proud of.Tip: A good way to cut square holes in the steel case is to use a cold chisel. One or two blows will cut a perfect corner through the steel case.Thanks for all your effort in producing this video.
Hi! This PSU looks really good! However, if you have three sets of banana plugs/binding posts (3V3, 5V, 12V) - why do you need the rotary switch? I would think that when you make these, you either have the rotary switch for selecting voltage and one set of binding posts, OR you do it a bit simpler with only the three sets of binding posts (even simpler is one red for the different voltages and one common ground).
I think the rotary switch just changes which output the meter displays.
he can't directly connect output high current to rotary switch because its sparks and i think after 5 time rotating switch,its messed up and die.
so if no rotaty switch so ho can remove anothers banana post during use one? i mean inorder that shows volt and current of just one post?
just one other concept remains :
use really instead of direct wirin to rotary to pervent spark and damage( anyway its randomly shot down unit becausr of china responsibility to probife minimums!😁
I've got an idea: Would it be possible to connect the built-in fan as the dummy load so the power supply turns on?! Would this be enough load?
hi. that is a good idea. for this power supply it will work. but the fan is consuming very little current and there are some power supplies which may need a bigger load. also you need to solder a connector to the yellow and black wires, so you can easily remove the fan cover if you need to reopen the power supply.
some modern PSUs have variable voltage output for the fan, so the fan's speed will variate depending on the load or PSU temperature. if you connect the fan to the 12V output, it will ad a load, but the fan will always work on maximum speed.
@@Sorin_DIYhello sir I’m a student I used this like my school project I followed all your step but I have a problem my lab psu turn for a second and then goes off i mean like screen voltage /amper it goes off when I give the current help me please
Hey Sorin... I was wondering if you could share the name of the electronic store or website where you purchased the components for your build. I'm getting into electronics and wanted to build a power supply for testing small circuits. After seen the one you built. I decided I wanted to build one. I really like your choice of components. Looks very professional. Anyway can you share where you got your components? I would like to order the same configuration. Awesome build!!!
What if I want to measure more than 10 amps? Also what would happen if you pulled more than 10 amps through your meter? I have a 3.3v @ 22a, 5v @ 22a, 12v @ 80a psu. As long as I’m gauging everything adequately, is there anyway to be able to measure it as well with a meter?
hi. if you use more current than the ammeter can measure, most of them will display "- - -" A and shouldn't get damaged. if you draw more current than the PSU can deliver, the PSU should have overcurrent and short circuit protections and should turn off, as you can see in my part2 video. you can use a volt/ammeter with a shunt, it can measure current up to 100A, but usually they are not precise with low current readings.

hi. you can use a 47ohm resistor.
@@Sorin_DIY thanks! I've got all the parts now. Just realised my psu(I'm using an atx650) has a power switch, can I just ignore the green wire? Many thanks
For the USB port, you should have used a car USB charger. The one that plugs into the lighter port and turns 12 volts into a steady 5 volts and has a regulator protection circuit on it. It would simplify things and make it safe for your phone
hi. thanks for the suggestion. but I will not use it to charge my phone. I'm using it to test different USB DIY devices with up to 4A. please watch the part2 video for more info about my power supply.
I'd use a buck converter.
Nice, but you should buy a cheap Dremel clone to cut the casing! ;)
In Soviet Russia, wire solders you.
Also, the blue wire IS useful to you. that -12V right there, used as the negative terminal for +12V gives you +24V.
I'm literally a beginner in electronics, and yet I keep finding horrendous misinformation. If I can find it, then I can't trust anything you say
Nice effort! Your hard work is reflecting from it!
I would like to request you to make another one...! Please try to make it adjustable to any number of volts (I mean not ONLY 3.3V, 5V, and 12V).... Secondly, please make it able to give 3.3V, 5V, and 12V at the same time without any rotary switch...
And thirdly, I would like to ask you that why are you giving three binding posts for GROUND? You can use one ground only I think... Can I know why you did so?
hi. I will probably make another one in the future with all the features included. but to answer your questions for now: 1) I've made a separate variable bench power supply, you can check out my other videos for that; 2) the 3 outputs are available in the same time and independent from the switch. the switch is only for the voltmeter. please watch the part2 video for more info; 3) the 3 negative binding posts are for connecting 3 loads on the 3 outputs in the same time and because I like symmetric arrangements, so I think it looks better this way. again, watch the part2 video for more info.
No. 12V delivers the most current. In very old ATX or AT power supplies sure, 5V did supply the most currend but these days (computers that are 15 year old or newer) have the most current on 12V. That's why your cpu, and gpu are powered by the 12v line.
i Like 9V and 1,5V , and 12V, like i dont know most usual battery yeah , and transformer output 12V , with that kind of output this would be better then most bench powers , because , mine goes to 200W , while bench top Transformer is 20-30W , that is 10 tiems better , but it needs to have proper voltage ,its useless without it, im making mine , i dont make a video , it will not be made to look good but to work good .
# ครับ สวัสดีครับผม น้าเด็จเซ็นเตอร์มาแลกเปลี่ยนให้กำลังใจคนทำช่องยุทูปนะครับ กริ๊งๆๆครับ
Should have included some fuses as basic protection but otherwise nice job.
Can we trick pcu Pwm controller to produce higher voltage then 12 v at 10 amp ? By modifying the OVP , OCP and dead time control circuits ?
some power supplies can be modified to increase or decrease the voltage with only a few volts, but it's very difficult. usually they are not stable anymore.
I don't advice you to turn an ATX power supply into a bench supply unless you know what you are doing! You can better get yourself a QJE PS30swv or an Amazon JESVERTY SPS1330 power supply who can deliver 30 amps of current instead of an ATX power supply!
I have one serrious question for those who want to help me
I have atx akyga ak-b1-400 +3,3V 23A, +5V 25A, +12V 18A , -12V 0,5A +5V Sb 2,5A total power 400W. Which buck Amperage should i use and what value should be the fuse inside?
Deadly. Including the side hole pun.
Mains and control voltage in one switch? Great idea. No idea of isolation.
Protection earth: botch when attaching without cable lugs. This makes my stomach turn.
Also: low voltages at the output, right next to the mains voltage supply line! Your shrink tube is supposed to be a joke, right? It can never serve as a correct isolating distance for mains voltage. And definitely not in the event of a lightning strike, when your super-mad botch falls down or you pour in coffee (Only some. There are many other error situations that an amateur ignores due to a lack of knowledge).
Now you could say, "That never happens" ... Exactly, it only happens ONCE!:/ Devices that are properly processed according to (safety) standards are suitable for precisely such cases ... Without killing their user.
P.S .: 10A through the rotary switch? **facepalm**
All this bullshit is completely irresponsible. And then in front of an audience. I would be ashamed ... or wait for the prosecutor.
I need help! my cat refused to go! what should I do?!?
excelentă treabă, omule! Poate mai lucrezi puțin la accent și pronunție în engleză. Seamănă cu Iliescu...
Nice but these PSU can't hold voltage with a modest load at 12 volts. Voltage drop below 11 volts! I tried scraped 200W, 300W and a 450W PSU units. Good for battery chargers though...For a robust PSU just have one that hols 13.8Volt..
Hi i have a PowerMan (InWin): IP-S300EF7-2 powersupply and i want to increase the voltage to 13,8 volt. Could u help me please. There is a 1mohm pot meter inside and voltage can be adjust from 11volt to 12.8 volt.
Great video on PS conversion! What gauge wire did you use for the leads?
thanks! I'm using 1.8 mm diameter wire, which I think is 13 American Wire Gauge.
i wonder why dont connect all of the positive wires just like the negative ones but put on them a diode so that way you will get a output from just two connectors and dont have to switch between them. Also great video and experiment
this channel is amazing, and i only found about it now....
i have a question tho - im a bit of an amatur with electricity (of course im following any safety instruction), and this is to be my first project (prbably a bit simpler then what you did). if i want a 48[v] supply, how can i wire 4 12[v] wires correctly? im afraid i cant figure the connections out on my own.
You are really genius to make the voltage stable add the resistor ...does it increase the current too? I need it to be to kick start a 12 Volt DC motor which require at least 5 Amp to kick start it but in normal turns it actually uses around 1.5 Amp. I know the SMPS has an Auto switch which will shut down the PSU automatically when it release too much amp more than it require to prevent it from damage. But i really need it just for kickstarting the motor. Would the resistor like you did will help?
hi. I think it will work with a dummy load resistor connected to the same rail. you can try to connect more resistors in parallel, to increase the current consumption if needed. you can also add a big capacitor in parallel, 6300uF at 25V, it will help to keep the voltage more stable.
@@Sorin_DIY Hey i found the solution to this already....thx anyway
Excellent explanation of what to do and WHY I should follow your instructions! Your accent is a bit thick for me to follow easily (I hope it gets better soon so I can consider subscribing) but I enjoyed your detailed explanation. I hope to see more video projects from you!
How i can connect an analog ampmeter? instead of the digital volt/amp meter you used?
it depends on the type of ammeter. you should find on internet the schematic for your ammeter.
@@Sorin_DIY the ammeter has a negative terminal and a positive terminal. I tested it by connecting it in series and it worked. But i don't know how to make it change the outputs that it reads. The 12V, 5V and 3.3V outputs.
I cant' figure out a way to do it using that rotary switch
the rotary switch is for the voltmeter. the ammeter is connected on the negative output in series with the load. the negative wire is common to all the outputs. you connect it like I did in my video with the 2 thick ammeter wires. one or more black negative wires come from the PSU circuit board, goes to one of the ammeter wires (probably the negative one) the other ammeter wire is connected to the negative binding posts.
Nicely explained and steady vues, and no loud horrid music, that's great..
Take note RUclipsrs, This is a perfect example on how to do a useful video.. My only comment is that the current sense wire and resistor is a waste of energy.
Perhaps using a 12v 12w bulb would be a good idea so your power supply could have a desk lamp fitted on top to light up what ever you are making when using this power supply.. Note the output smoothing is usually done by the motherboard in a PC, those nice rows of capacitors that when dried out burst open and short out the motherboard. It's nice if you can fit some big value capacitors to the two 12v outputs and the 5v use a 16V cap for the 12v output and a 10v cap for the 5v output. use the highest UF value you can fit inside the box or even mount them on the rear of the box. Then fit a 1k resistor across each capacitor to empty the cap and lower the voltage to zero when it's switched off. a 1/4 watt resistor is fine for this.. as the current will only be 150 milliwatts .. great Video and well done.
hi. thanks for the feedback. the capacitors are a good idea.
whoa, you said a mouthful. OLE!
5v 선에 시멘트 저항을 장착을 하는 이유는 무엇입니까 ?
Thanks Sorin.. Mine is done.. ibb.co/hKMy7sb Remember to test the load resister.. I had a bad one with a really low resistance, it's easy for a faulty one to send things south... I included a post that's not connected to the meter for my LED light-strip.. things are getting along. Had one of my kid's gum tattoo's lying around.. She looks like she can dance on a pole now.
I never understand why people always have to add annoying background music to their videos - this is neither entertaining nor helpful for viewers to understand the actual content of the video (on the contrary, because many simply turn off the sound). , Well, the content here is fairly simple and everything is intuitive, but instead of all of these entertaining efforts, you could have shown simple schemes of what your peripherals are all about. Apart from this, you've done it well ...no offense .)
I don't like the music (This is the problem in every tutorial :) ), but it's a very interesting video. I have to do one for me. There are many ideas (the USB port for exple). thanx.
Hi Sorin,
I still have some questions about this project and I have a few minor problems. I think I have connected everything as it should be, but I do not measure the correct voltages on the binding posts, the voltmeter does give the correct voltages. is it possible to make the schematic even more clear because i am a beginner in electronics.
Nice power supply, nice tools. But it looks the voltmeter is not for measuring output voltage but to monitor the voltage of any of three outputs on which a load is connected, a similar method used by someone else I watched on RUclips😊
Hello, we have an agricultural land that has no electricity. Now, if we want to use a motorcycle battery, which is 12 volts, to get different currents, such as 10 or 12 amps, what transistor should we use?
Just curious... to save space, could you have only one ground plug?
yes. but I think it looks better with 3 pairs of binding posts. and you can use all of them in the same time.
Hola! Después de 1 año sin mas comentarios…. felicidades por este tutorial ; Solo me gustaría saber que conexiones Tiene para iluminar el interruptor verde ( Negro y verde ) ¿ que más? L y N ¿ como?
Disculpa entiendo muy poco Inglés.
Un saludo.
The music is not needed. I was finally forced to stop watching and give you a thumbs down. You have all the talent needed- please stop using background music. Best of luck.
thats not DIY .. thats just a rich kid with unlimited supplies haaha if i had that iam probably building a whole mecha by now not simple stuff
... keep it up we want better harder projects
So it's only 3.3 5 and 12v? Can't you use a buck boost converter to make a higher dc voltage?
Yes. I plan to make a better power supply conversion soon with more features.
OMG This is NOT a BENCH power supply. It is a SMPS power supply./...BIG DIFFERENCE....Do YOU know why?????????
Very Nice !
