DIY - Convert Old ATX PC Power Supply To Bench Power Supply

[@MarcelHuguenin]

By far the finest build I have come across regarding ATX power supply conversion to a general bench power supply. Very well done!

[@creativesolutions-diy]

Thank you for your words!

[@pjesapjes]

agree !!

[@futuratell3667]

Is this power supply within reasonable ripple output? Or would it benefit from further reduction of dc ripple.

[@mr.makeit4037]

Outstanding! Liked the addition of another potentiometer to fine tune your voltage. I'm choosing your schematic to build mine.

[@creativesolutions-diy]

Yeah! The fine tune is very useful!

[@TheWtss]

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.

[@creativesolutions-diy]

Thank you and I absolutely agree with you!

[@tiberiuoros9733]

You are right Mr. Rick McCaskill, "this is the best version I have seen". Excelent Project.

[@creativesolutions-diy]

[@creativesolutions-diy]

[@cuentos.narrados]

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.

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

[@aswingsharif6729]

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.

[@lorenzo.c]

If I have to pick on something, you should have shorted DATA+ and DATA- on the USB host connectors you want to be detected as "AC Charger" mode. Also I'm a bit uncomfortable on exposing GND as the VCC of the USB port you power from the -5V rail but that's probably just me. By the way, I think the quality of the video is great (I particularly liked how you edited the sound)

[@creativesolutions-diy]

Thank you for the tip, I will investigate the short DATA+ and DATA-. If you are a bit uncomfortable on exposing GND as VCC, you can use the normal 5V (red wire) for usb as well. Thank you for watching!

[@lorenzo.c]

@@creativesolutions-diy , the standard to refer to is Battery Charging v1.2 Specifications for USB 2.0. The core of the matter is that USB 2.0 made USB an interface which could also deliver power (more than 500mA) and deliver just power. In order to make it possible for devices to understand if the cable that had been plugged in could source more than the old 500mA and, at the same time, for the manufacturer of PSU to keep making reliable but cheap 5V units with only a change of connector the BC Spec standard defined having DATA+ and DATA- shorted as the solution. You can use an app like Ampere on a phone: when the phone detects a "dumb" charger the app says "AC Charger", when the phone detects an host which can communicate (but is not expected to deliver more than 500mA) then the app will say "USB Charger". My "discomfort" about grounds comes from these considerations: if you were to power two devices from these two USB ports and those two devices ended up being electrically connected in some way, then the "GND" in each of them would actually be 5V apart and the consequences would be bad. I admit it's unlikely but here is the designer of electronics thinking about what could go wrong rather than the tinkerer. Thank you for the video and keep up the good work.

[@videotronicmaker]

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?

[@creativesolutions-diy]

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!

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.

[@JasonOfTheB]

The USB connected to the - 5V rail is a really bad idea. It gives you some more amps, but also a GND that is on -5V compared to the other GND in the same device. If you use more than one supply for a single device, you create a nice short and could burn through your cabling or even destroy the power supply

[@creativesolutions-diy]

You are right, it's not a good idea, but usually the usb port it's not used to power a device together with another output. But yes, the best it's use the +5v instead of -5v

[@JasonOfTheB]

@@creativesolutions-diyI see how confident and comfortable you are working your way around that ATX Power Supply .But I don't think many of us have those hand tools you have in your service. 1-) Converting the power supply into bench power supply is the seen part of an iceberg which you successfully demonstrate in this accelerated video in a fashionably manner It would have been time bound otherwise. 2-) Being able to acquire and use those hand tools comes with a territory. I feel I must say I agree with Bob! This outstanding project could have been more productive should you at least put the tailored version of this footage put into stages that progressively explain the whole process step by step. Could you possibly upload the slowed down and the shorter version of this video on your website for slow learners and serious builders like me! Thank you!

[@robertthompson5163]

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.

[@ubermick4208]

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.

[@armandodenaro5406]

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

[@lmanghg1257]

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

[@creativesolutions-diy]

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.
