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.
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.
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).
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.
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?
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.
Great video. What's your wiring for the LED rocker switch? Black for Ground, Green for + but what wire for the centre ACC post to make the LED light? Red?
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
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.
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.
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
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 !
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?
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.
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?
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 ?
Great video! I am gathering the parts to build my own. Question: I don't understand the purpose of the 10 ohm 10 watt resistor across the 5volt line. I have seen this in other designs. Thanks.
Computer PSU style supplies need some load to work properly, otherwise they sometimes wont start or output voltages fluctuate. So this resistor is that load.
5:16 When so it's a must be location at 12V or can be location of a Chip if are be about of 0-30V (When so I do be know then Additonal USB's with Module can be so useless if are be for "USB Standby only")
Muy buena, y muy bien presentada pero q pasa si la carga entra en corto en la salida de 5v, o la de 3.3, o tal vez la de 12v, bien la fuente se protege pero y la carga se quema.
Excellent Work!!! I have 2 question. ¿the dc-dc module can adjust the supplied current?? and the other question : that dc-dc module can supply (elevate) the voltage more than the 12v from the ATX??
Hello, I am Iranian. Iove your videos. And I really liked the design uoy did for power. Can you send me the program with which you designed that label, please or tell me its name?
Gracias por la información. Tengo una pregunta, instale los tres potenciómetros pero no funcionaron bien, luego observe en otro video que los potenciómetros deben ser de multigiro y de la misma referencia del modulo convertidor.
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.
amazing work! congratulations, thanks for sharing. Do you have the link of the reuploaded project? because it seems to be down. Thanks! greetings from Argentina
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
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!
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
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!
You are right Mr. Rick McCaskill, "this is the best version I have seen". Excelent Project.
Thank you Tiberiu Oros!

Hello, is the 10w resistance always necessary? What is it for? If I put a switch without an LED, do I need it? Thanks
Is that correct 4 amps is the max load these can handle??
Why you use 10ohm 10watt resistance between 5v and gnd?
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.
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....
¿Por qué se necesita una resistencia de 10 vatios / 10 ohmios para conectar con Tierra y 5v+?
Great video.
What's your wiring for the LED rocker switch? Black for Ground, Green for + but what wire for the centre ACC post to make the LED light? Red?
yes.. led not function..
Great DIY, Is it possible to have the first sticker with diameter before to drill the holes or to cut the metal ?
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
Why is resistor 10 watt/ 10 ohms necessary to connect with Ground and 5v+?
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 ?
Where did you get the labe from that you used as a templet for the lay out?
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!
The project link is not working! Would like to print the stickers out. Help!
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?

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.
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?

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.

I think the 5 volts of the switch is only used to power the led
hi, why the circuit need a resistor 10 ohm beetwen ground and 5 Volt ?
why digital voltmeter measurement terminals both pins go to GND?
Is the wiring correct for the USB sockets? One seems to be wired the opposite polarity to the other one.

Thank you!
hi. Why in one of the USB port you connect the -5VDC from the power supply?
probably for the always on function
Excuse me, Sir. Is xy-sjva can be replace with xl4016?
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!
Excelente vídeo!!!
Una pregunta, donde puedo encontrar la pieza de plástico que sujeta los dos USB???
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.

Hi, can i connect 12v and 5v together and then use a DC to DC module to get more power from atx?
Hi, thank you very much, can you use 10 ohm 25 watt resistor instead of 10 ohm 10 watt resistor?
The project page is not accessable from the link, is the information still available somewhere?
Nice, how is the current adjustment on this? Do you need to disconnect and short first or can you do it in situ?
