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.

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).
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, 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.
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.
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.
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?
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.
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.
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.
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")
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
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!
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.
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 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.
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?
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?
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.
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.
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 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.
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.
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.
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!

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
Very creative solution to use the PSU case itself as the main case. Also, nice work on including USB outputs.
Whats the awg of the wires you used for the power connectors and ground?
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!
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.
Dude, he did put the resistor value in the video. not to mention that multiple people have mentioned it in the comments as well.
Is that correct 4 amps is the max load these can handle??
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.

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.
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.

+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.

What's the name of the orange wire/cramper you're using and any good recommendation for a soldering station? Thanks
Is the wiring correct for the USB sockets? One seems to be wired the opposite polarity to the other one.
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....
Você colocou ela pra venda no mercado?

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 ?
What's the function of the small blue PCB you added with the large wire wound ferrite ring & where did you purchase it from ?
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")
Great DIY, Is it possible to have the first sticker with diameter before to drill the holes or to cut the metal ?

Why is resistor 10 watt/ 10 ohms necessary to connect with Ground and 5v+?
Best ATX build I've seen so far - beautiful!! 👍👍
I like that small heat gun. Where can I get one?
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?
project link is down, i want to know how you got the 30v
Nice project.
0:32 But where I can get the picture file ? 😁
I am having trouble wiring the DC-DC Step up Down Converter to the variable resistors.
Hello, is the 10w resistance always necessary? What is it for? If I put a switch without an LED, do I need it? Thanks

why digital voltmeter measurement terminals both pins go to GND?
hi. Why in one of the USB port you connect the -5VDC from the power supply?
probably for the always on function
Great work! Probably the best atx bench supply build I've seen! Tip my hat 🎩
Thank you very much!
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.
Why you use 10ohm 10watt resistance between 5v and gnd?
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!

Boa tarde , onde conseguir o adesivo frontal para fonte atx , grato.
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.
Nice, how is the current adjustment on this? Do you need to disconnect and short first or can you do it in situ?
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!

Hello
Very good and precise work. Accept recognition from Slovakia, Košice.
Everything good
Ahoj
This is really a very nice power supply. Could you maybe please email me the print files for the front cover?

The 10ohm10W res. function as a dummy load. Some ATX PSU won't start (turn on) if there is no load.

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.
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
¿Por qué se necesita una resistencia de 10 vatios / 10 ohmios para conectar con Tierra y 5v+?
Nice job! Far better than mine. Going to build another with a step-up and this ones got a nice layout.
