I just watched your build and found it very interesting for my level of electronics.(LOW)!!! For my level and a lot of other people’s level this is a great job to learn how to work with the parts and such to put them together. I also read a lot of the comments and it seems a lot of people seem to forget about us uneducated learners. We need these jobs to learn from.
This is THE diy power supply, look no further. I used your fine adjustment pot solution for mine. I had a problem bc i didnt use the same dc dc converter so i had to use a boost one and a buck one, in top of that i needed -12v with at least 5 amp (for chip power amp test, like 3116d2) so i had to use 2 pc smps in series, but it turn out well, i used an old (really old) dual cassette deck as enclosure. Thank you very much for the tips.

Potentiometer wiring on the schematic, I'm not sure about the orientation of the new pots and which post should be 1, 2, 3. On the converter PCB, I'm counting left to right, with the square "through hole" as 1 on the left. On the New pots, looking at them with the post pointing toward me, the images I've found, are labeled 1 to 3, left to right. Is that the way you meant in the diagram or reversed? Thanks, I'm looking forward to completing this! Looks great.
Hi, I have a similar psu without green cable and a gray cable, can you please advise what you do with the gray cable, did you just cut it away? And what is the resistor type you are using? It would be nice if you can put the details on the video.
A tip on soldering, tin the wire first and what you are soldering the wire to. It makes for a better and stronger solder joint. Also avoid what's called "cold joints" if there is not a shine on it when it cools then redo it. Poor joints can break easily.
The good: 1. enlist the components and their buying links 2. motivating viewer to build one. The bad:1. Fast forward of full time to build this, since you are too lazy to edit. If you edit unused steps you can run the video in normal speed and viewer can understand better the steps 2. No explanation on what are you doing on particular time 3. No knowledge sharing about which atx cable used and unused, the boost buck module and R shunt, etc 4. Background music represent low confidence level on the video quality while your video is actually good. See for a good example: DIY PERKS, no music, full explanation. 5. At least: SUBTITLE ON EACH STEPS would be appreciated.
Great work. But you didn't test current potentiometer I was expecting :( Can u tell your test results at 24-30V. Any issue? Like voltage drop and is it safe to use these usb's for charging smartphones? Thanks.
Others have made atx workbench power supply videos and you still came up with something new. Great job coming up with modifications and a really nice label in front. Well done! How many amps are you able to get out of the variable side?
Nice work, I think you would love a dye grinder, you could replace most the tools used here and save time. I love mine, wish I had an excuse to use it more.
Muito bom vídeo. Pena não dar para ver o valor da corrente máxima seleccionada. Mas suponho que começando com uma corrente baixa e depois ir aumentando não deve danificar o circuito?
For all of you asking "WTH is that resistor on the 5V doing there?": For the PSU to correctly regulate the +5V output voltage it needs to have some sort of load attached, at least 5W to trick the PSU into thinking its attached to the motherboard.
Can you tell me what was the original value of trimpot which one is removed from buck converter. I’m using Xl4015 buck module which has 103 trimpot for cv abd cc what should be the pot value according to your circuit.
Well done, I have now done one of my two tasks thanks to this : 1) Find a good makestuff channel to subscribe to - Check! 2) Make an ATX lab power supply - will do soon!
Great job. I have a question about the roket 3 pole led switch. Can you explain how it works? It is a led with polarity it seems doesent work in realtà but only in video
Hello, first congratulations and thank you for this great video.at 11:26, for the potentiometer 1 K you do not solder the wires in the same order as on the diagram, is there an error on the diagram? (video: orange, white, brown / diagram:brown, white, orange).
Are there any potential problems with using multiple ports at the same time? e.g. supply an arduino on one of the lower fixed voltages and maybe cpu fan drawing .5-1A on fixed 12V and another load on the variable voltage and making sure all this adds up below the rated specs
It is really an impressive work! thank you. I want to ask you about the custom label that you made for the outputs, can you upload it ? I want to print it and use it.
I got a DC-DC Step ZK-12KX-V2 but i can't get the output voltage higher than the input voltage, i dont know if the module its broken or if im doing something wrong. I havent change the potenciometers, it has the original ones.
I have had a go at making one. Tested it all working great with original pots on the board, but once I extended out to the 3 front pots, then the smoke leaked out! Your website is down. I tried to access to check details. I had to rely on stopping video and getting scratchy pictures. Back to Ali express to order another 0-30v board
this is a great idea, but it's pretty intrusive and parts-intensive. What if you made this as an external add-on that would just clip onto the existing ATX connector of any such PC power supply ?
nice video but just warning connecting USB ports like this (it will work) but some devices are making problems when charging. (learned it the hard way :) )
Can I solder a normal 100 kOhm resistor to a 100 kOhm multiturn potentiometer in order to get to 200 kOhm? Can't find a 200 kOhm multiturn potentiometer! My step up booster uses the 204w trimmpot
Any tips on converting a 50-100amp Single rail PSU for in-house/bench car audio testing? I need to be able to test car audio equipment with current pulls of up to 100amps (looking into 300amp PSUs as well) thinking I can use this same deal on a larger h it and just switch out what I want/don’t want.
Excellent tutorial but cannot for the life of me get the power switch LED to illuminate. It seems you have the voltage + going to the common pole on the switch, with ground in the centre pole, and then green on the top. Which makes sense, when the switch is thrown, connects the ground and green to kick the PSU on. But the LED is pole sensitive, so needs the + on the switched side, I think? I mean, the switch itself works, soon as I activate it I get power to the fan, and the orange/red/yellow wires read 3.3/5/12 volts.
Ciao ho anche io lo stesso problema. Ho seguito attentamente sia lo schema che il video ma azionando l'interruttore funziona tutto tranne il led. Nel video sembra funzionare ma in realtà no. Tu hai risolto? Ti sarei grato se mi dici come. GRAZIE
The hardest part for me would be forming those holes on the front panel. Not everybody is equipped with the right tools to make and smooth out those holes.
Everything is very good, but I have 2 questions, what is the 10w resistance 10 homnios for, I am not an expert in electronics, but does it seem almost a short circuit in the 5V line? And the usbs I understand that they need some resistors on the data pins so that the device (cell phone) takes 1A or 2A if they do not have those special voltages on the data legs it only takes 0.5A
You are right, if you will use the usb port to charge the cell phone you can short the -Data with +Data pins. The 10w 10ohm resistor is for dummy load because computer PSU style supplies need some load to work properly, otherwise they sometimes wont start or output voltages fluctuate.
Hello, I have a question on the switch wiring : if the green and the black wire are connected, the pc power supply should be ON, but if we change the switch state the 5V is directly connecter on the GND... isn't it dangerous ? That's a big question I have : why do we have a 5V on the switch, because wiring the green and black wire together should be sufficient to have the power supply activated. Thanks for the possible answers !
I tried to do this, but the CC CV Boost/Buck Step Up/Down Converter DC-DC 5V-30V is always busted.I don't know what the problem is; I followed the diagram.
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?

By far the finest build I have come across regarding ATX power supply conversion to a general bench power supply. Very well done!
Thank you for your words!
Is this power supply within reasonable ripple output? Or would it benefit from further reduction of dc ripple.
Outstanding! Liked the addition of another potentiometer to fine tune your voltage. I'm choosing your schematic to build mine.
Yeah! The fine tune is very useful!
If you didn't want to be copied in your work, you haved complete success!!!!Congratulations!!!

Very creative solution to use the PSU case itself as the main case. Also, nice work on including USB outputs.

+1 music is killing me. At least dont monetize and force us ads and length if its gonna be straight through. Cool build tho
@@collinrohwer1790 the music in the video even that bad compared to other indian diy ers
Also, no smoothing caps on the lines. This video is a beginners overview at best, and a hazardous waste of time and parts at worst.
Great work. But you didn't test current potentiometer I was expecting :( Can u tell your test results at 24-30V. Any issue? Like voltage drop and is it safe to use these usb's for charging smartphones? Thanks.
The project link is not working! Would like to print the stickers out. Help!
Others have made atx workbench power supply videos and you still came up with something new. Great job coming up with modifications and a really nice label in front. Well done! How many amps are you able to get out of the variable side?
The max amps you are able to get in the variable side depends the DC-DC module. The module that I used I can get 4 amps maximum. Thank you!
Only you know what ur doing ……. The video is too fast and not showing step by step clearly
It looks like he had a project link in the description that's not working for me at least. Really cool power supply tho
Une alimentation très bien faite ! Bravo .
A very well done diet ! Well done .
Thank you very much!
Is that correct 4 amps is the max load these can handle??
Whats the awg of the wires you used for the power connectors and ground?
Could you explain why the usb ports are connected like this? Why same gnd is connected to gnd in one and to vcc in another one?
Nice work, I think you would love a dye grinder, you could replace most the tools used here and save time. I love mine, wish I had an excuse to use it more.
¿Por qué se necesita una resistencia de 10 vatios / 10 ohmios para conectar con Tierra y 5v+?
Why is resistor 10 watt/ 10 ohms necessary to connect with Ground and 5v+?
Excelente Video... Muchas Gracias.. Argentina
@nestoreduardo8627 ¿Podrías compartir lo que descargaste? Ya no está disponible
Why you use 10ohm 10watt resistance between 5v and gnd?
Muito bom vídeo.
Pena não dar para ver o valor da corrente máxima seleccionada. Mas suponho que começando com uma corrente baixa e depois ir aumentando não deve danificar o circuito?
Is the wiring correct for the USB sockets? One seems to be wired the opposite polarity to the other one.
That was beautiful! Thanks brother, from Uruguay

Gracias por la información. Pregunta. De cuantos homios son los potenciometros.
Soy aficionado
Gracias
Obrigado,
potenciometro 50K + potenciometro 2K + potenciometro 1K
project link is down, i want to know how you got the 30v
Can you tell me what was the original value of trimpot which one is removed from buck converter.
I’m using Xl4015 buck module which has 103 trimpot for cv abd cc what should be the pot value according to your circuit.
Well done, I have now done one of my two tasks thanks to this :
1) Find a good makestuff channel to subscribe to - Check!
2) Make an ATX lab power supply - will do soon!
how do you get adjustable voltage... all i ever see is a 12v source? Yours goes to 30v.
A boost converter, it increases the voltage above the 12 volt input
why digital voltmeter measurement terminals both pins go to GND?
What are those snips you used to cut the metal?
Great job. I have a question about the roket 3 pole led switch. Can you explain how it works? It is a led with polarity it seems doesent work in realtà but only in video

Hi why did you connect the Usb to the -5v? The second was connected to the +5v stb but how much amp you get on this line ?
Hello there, is there a possible way to get those stickers you used in the beginning of the video? A pdf would be sufficient! Thanks!
Me ha gustado mucho el video.
la mejor idea para fabricar fuente de laboratorio que he visto.

Hello
Very good and precise work. Accept recognition from Slovakia, Košice.
Everything good
Ahoj
hi, why the circuit need a resistor 10 ohm beetwen ground and 5 Volt ?
What are those male connectors he crimps after putting on the ends of two wires? Thx for any help.
I got a DC-DC Step ZK-12KX-V2 but i can't get the output voltage higher than the input voltage, i dont know if the module its broken or if im doing something wrong. I havent change the potenciometers, it has the original ones.
Probably the module it is broken...
where did you come up with the software or what did you use to make the design for your sticker, knobs, controls and such, lettering, numbers.
Paintnet haaaaaa
@mattrowe1229 Could you share what you downloaded? It is no longer available
Is there anyway to run higher amps? For example my PSU runs 12V at 49amps. I need at least 25A to power a charger I have.
This power supply. Can i use mobile phone mother Board??
Great work! Probably the best atx bench supply build I've seen! Tip my hat 🎩
Thank you very much!
Wow this is a really great idea. Nice job. I'm making one
I have had a go at making one. Tested it all working great with original pots on the board, but once I extended out to the 3 front pots, then the smoke leaked out! Your website is down. I tried to access to check details. I had to rely on stopping video and getting scratchy pictures. Back to Ali express to order another 0-30v board
This looks amazing!
what can be replaced with a 10w 10Ω resistor and a 2k potentiometer
thank you
this is a great idea, but it's pretty intrusive and parts-intensive. What if you made this as an external add-on that would just clip onto the existing ATX connector of any such PC power supply ?
there are modules that do just that, minus the fine tuning.
It is possible to use ceramic resistor?
No you can't. The max watts of the metal film resistors is 3W, I recommend 10W minimum
It's a perfect project. Great job. Could you tell me if I will use ATX 350W with the same equipment? It will be worked?
Absolutely yes!
nice video but just warning connecting USB ports like this (it will work) but some devices are making problems when charging. (learned it the hard way :) )
Hello, is the 10w resistance always necessary? What is it for? If I put a switch without an LED, do I need it? Thanks
hi. Why in one of the USB port you connect the -5VDC from the power supply?
probably for the always on function
What's the function of the small blue PCB you added with the large wire wound ferrite ring & where did you purchase it from ?
What's the name of the orange wire/cramper you're using and any good recommendation for a soldering station? Thanks
Nice job! Far better than mine. Going to build another with a step-up and this ones got a nice layout.
Can I solder a normal 100 kOhm resistor to a 100 kOhm multiturn potentiometer in order to get to 200 kOhm? Can't find a 200 kOhm multiturn potentiometer! My step up booster uses the 204w trimmpot

The 10ohm10W res. function as a dummy load. Some ATX PSU won't start (turn on) if there is no load.
You are right, if you will use the usb port to charge the cell phone you can short the -Data with +Data pins.
The 10w 10ohm resistor is for dummy load because computer PSU style supplies need some load to work properly, otherwise they sometimes wont start or output voltages fluctuate.
Very Fast video .Circuit Daigram not shown. why ? This video not useful without diagram.
Hi, can i connect 12v and 5v together and then use a DC to DC module to get more power from atx?
Hello, I have a question on the switch wiring : if the green and the black wire are connected, the pc power supply should be ON, but if we change the switch state the 5V is directly connecter on the GND... isn't it dangerous ? That's a big question I have : why do we have a 5V on the switch, because wiring the green and black wire together should be sufficient to have the power supply activated.
Thanks for the possible answers !
I think the 5 volts of the switch is only used to power the led
Why load resistor us in this project?
I tried to do this, but the CC CV Boost/Buck Step Up/Down Converter DC-DC 5V-30V is always busted.I don't know what the problem is; I followed the diagram.
will this circuit work for MBR/short
Can we use 12v and 20 amp
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?
Very nice build. I have question could I use a 12v cooling fan in place of a dummy load?
I think it is better to doesn't use a fan, because it has a very low resistance....
Great DIY, Is it possible to have the first sticker with diameter before to drill the holes or to cut the metal ?
Hello, i love the proyect and i what to make it for my father. May i ask you the file for the vinyl design? The proyect link doesnt work. Thnks!!!
Very nice, the "Old ATX" power supply is new :)
