ATX Bench Power Supply - Convert a Computer Power Supply

A computer ATX power supply can be easily converted into a versatile and powerful power supply for your workbench. In this video, I’ll show you how easy it is to make that conversion.

A power supply is an essential piece of equipment for any electronics experimenter. While you can get by with USB adapters and “wall warts” having a capable high-current source of 3.3, 5, and 12 volt DC power will take your experimenting to another level.
Commercial power supplies with these sorts of current capabilities can be very expensive, however, there is a much cheaper alternative. With some simple wiring, you can convert an ATX power supply from a desktop computer into a reliable and capable workbench power supply.
Even if you need to purchase a new ATX power supply this method is still a lot cheaper than buying a commercial workbench power supply. And chances are that you won't need to spend any money at all on the ATX power supply, I salvaged mine from an old Windows XP computer and it works just great.
There are two types of ATX power supplies commonly in use, I will show you the differences between them. Either model can be used in this project.
Here is the Table of Contents for the video:
00:00 - Introduction
04:36 - Parts used in Project
10:06 - ATX Supply pinouts
13:46 - ATX Supply Inside
16:17 - Testing ATX Supply
19:14 - Hookup Diagram
22:48 - Building the Power Supply
30:17 - Testing the Power Supply
31:59 - Adding a Power Meter
One note - there are many ways to do this and I outline a few of them in the video. Several methods (including the one I used) involve opening up the ATX power supply. If you do that BE VERY CAREFUL as some of the components in the supply can retain a high-voltage charge for hours or even days after the supply has been unplugged.
If you are unsure about opening up a power supply (or if you have a new one still under warranty) don’t do it, you can still build this project another way. I go over that at the conclusion of the video.
As always there is an article on the DroneBot Workshop website that accompanies this video.
Hope you find this video useful and if you haven’t already please subscribe to the KZfaq channel. Thanks!

@Vermilicious 5 жыл бұрын

Some newer power supplies have several "rails" to separate the load. If you want to pass through a lot of current, you should probably consider which wires you use, and not just pick the ones on the motherboard plug. Also, if you don't want to open the power supply, there's no stopping you from simply leaving things unconnected. Some power supplies also have modular connectors, which makes it even easier to pick the ones you want. In any case, these things are so easy to find. Nice video, showing how easy it is to use.

Thank you for another great video! I have built a similar bench power supply from an old ATX I had about a year ago. It has proven extremely useful and was quite easy to make. If you are at all interested in electronics, just do it! It's easier than you think, just be safe. Also, I would suggest adding a USB port to the 5V line, as a power outlet for USB connected devices (Arduinos, for example). It makes the bench a bit more useful.

@SuperFunkmasterj 3 жыл бұрын

Very nice video, well-explained and thorough. I do have a minor quibble, however. The ATX spec defines the PSO function as edge-triggered, rather than level-triggered. In other words, you do not have to lift PSO to +5V and keep it there - simply pulsing it to +5V will turn on the supply. The spec actually recommends a momentary switch for this function, rather than an SPST as you have used here. Turning off the supply is a matter of holding the momentary switch down for 4 seconds. So one brief pulse to turn on, 4 seconds to turn off. I have not seen any damage to PSO circuits as a result of continuous application of +5V, just saying it's not part of the spec. Personally, I use the ignition switch from a 1974 Chevy Vega (the only part of the car worth keeping) mounted on the side of my case to do the start-up. So far, the PC has not leaked any oil, which confuses a Vega key.

NICE! I've had to quit my job so I can watch your videos. I must say, you are the last guy who needs to ask for subscriptions! I wasn't two minutes into the first one I watched before subscribing. So, allow me to give back. I built such a supply some years ago, but utilized the -12 voltage and an LM338 variable voltage regulator to give me up to 24V and is fully adjustable. The current is limited to the maximum output of the -12V side, 800mA in my case, but it allows me to dial in voltages in between 3.3 and 24V 'cause sometimes you just need something different. Note that zero volts is not relative to ground of the unit; it is actually -12V relative to ground. But that's not the good part... I used a very used and cheap ATX power supply and it quit after about a year. (Could be 'cause I taxed the -12V output.) When I replaced it, I decided that I wanted it to be plug-n-play so I searched for the correct housing and pins. Now I can change out the power supply by unplugging and re-plugging. So, here are the part numbers: Molex #39-01-2201 Plug housing $1.38 as at 1/15 Molex #39-00-0076 Pins 0.22 as at 1/15 These are available at Mouser. Note that you'll need a special crimper for the pins. I'm particularly excited about what I've taken away on the subject of the Arduinos. You've opened up new doors for me on that front. The orderliness of your pegboard and the cleanliness of your bench is frightening. How do you get anything done?

Hi man, great video! I love how clear you are explaining everything on your channel. Thanks. I have a question. I made my ATX bench, and all the outputs are ok, but with a slight instability in tension, like +/- 0.02 volts, and when I want to use it to power my servomotors (controlled by Arduino), this slight instability makes my servos jitter very hard. Do you know what can be de cause and/or solution to this? Thanks in advance everyone!

Hi, from South Africa, I do enjoy your presentation on all things electronic, I am a 73 year old retired Elec-Eng and I lecture for 10 weeks, once a week, August to November, at a "CAD" College. The students I lecture Mechanical and Architectural students and we do Electrical Design using AutoCAD and SolidWorks Electrical CAD. I have a few "breadboard" exercises for the students and I think your "ATX" power supply/bench supply is just the thing for these exercises. I will be visiting the computer-scrap-joints to ferret out a few ATX's units before August this year. thanks

I picked up an ATX at a second-hand store for around $5.00. I had no idea what to do with it. Thank you for the idea of a multi-volt power station.

Got a spare PSU, been wondering how to convert it into a power supply for my Electronics Projects, Thank you awesome video good explanation and I have one of those meters that I've never used too, job done, just waiting for the parts.

Just a note: my power supply has a brown wire and this one, if present, needs to be connected on the 3.3V line. Now I need to know if the resistor on the 5v line is mandatory (because the power supply seems to work without it)

Another great video. This was a huge help for me. Gave me a great idea for a 3.3V, 5V, 12V power supply all in one. My favorite channel on youtube!

I built one of these years ago and it was very useful. Instead of the load resistor on the 5V line, I attached an old style, filament light bulb. I mounted it on the PSU box and it helped inspect circuit boards at times. I also added a custom 0V dock on the box for my multimeter - one wire frequently needs to be grounded.

Great video, well explained and very useful. Quick question - what rating fuses did you use for each of the 3.3v, 5v and 12v lines?

And what resistance resistors

How do you tell if a particular supply requires a load as in a 8 to 10 ohm power resistor? Thanks

i am in love with this channel, im studying so i can teach my lil man, i know how to do things but terrible at teaching or explaining, so this helps me to put my experience into words.

Really love your site, very informative and detailed in your explanations. You make it easy to follow and understand how simple it could be, though it did not seem like that at the beginning. Thanks so much.
