ATX conversion to bench power supply (fixed & variable)

Hello friends!
In this episode I will show you how I converted an old ATX PSU into a bench power supply with fixed and variable outputs.
Some of you asked me for this video, but I also wanted to make it for a long time.
Now I have a more colorful power supply that will replace my 2 old ones.

I only came here for a how-to on a power supply from a PSU, but I stayed because of your humour and your cat! And it's a great video and how-to :^)

"Words cannot capture the awe-inspiring beauty of the video showcasing the ingenious creation of a 12V energy source using nothing but scrap metal. I am incredibly grateful for the opportunity to witness such creativity and resourcefulness in action. This video not only highlights the power of human ingenuity but also serves as a reminder that beauty can be found in the most unexpected places. Thank you to the creators for sharing this remarkable project, as it truly showcases the limitless possibilities that lie within our grasp when we dare to think outside the box."

I am a bit of an electronics-project fan too and I appreciate your video. Too-many times, instructional videos turn into unnecessarily over-complicated and "waffly" rubbish. You have shown EXACTLY what is needed and WHY in one simple video. Well-done. The cameo-appearances by 'El Gato' are an excellent segue into the next scene. The wry humour is also appreciated. Thanks for a great video.

Thank you very much, this video is very informative and straightforward without any unnecessary information. I like the idea that you use the ATX's normal outputs as well. The way you do the layout is also very practical for me.

Sorin, I want to thank you for this. I have a car subwoofer with a class D car audio amplifier to power it. I have been trying to get a reasonable power supply for some time for it, but lately, I cant get anything that is either outrageously expensive, or outrageously underpowered. PC power supplies are able to provide the wattage, but its difficult to provide all that amperage through those wires, this actually gives me a solution to my amperage problems with the amplifier. The power supply cuts off when normally plugged in because it cant provide the massive amount of wattage but with all of the wires together in one place, it allows me to have FAR MORE amperage to the amplifier, therefore allowing me to drive it harder. This is important because I DJ and I need really loud speakers in certain situations. This is awesome!

I also have used the same volt amp meter for my small diy project and yes it adds an unwanted voltage drop even at 1 amps but I still used it because my build has an average current draw of 150mA - 300mA. Also your cat is a really good assistant

@SuperFredAZ Жыл бұрын

maybe you could do a conversion using a 19 V laptop supply, put it in a wooden box add the volt/ammeter binding posts. With a 90+ Watt power supply you can still get quite useful current, and of course this is 100% safe!

You have not used -12 volt in series with +12 volt because -12 volts has only 0.5 amp. If you use it in series you get 24 volts but 0.5 amp only as output.

If you connect two such power supplies in series, you can raise the voltage to 48 volts using -12 volts from one of the power supplies.

I used to install signs and used that self adhesive vinyl fairly often, for future reference if you make up a spray bottle with water and add literally one tiny drop of dawn dishwashing soap (no more than the smallest drop!) you can spray the solution liberally to the back of the vinyl and the surface it is to be adhered to giving you the ability to move it around and get it exactly where you want it, then you squeegee any air or water bubbles out and it sticks very well, won't work on a porous surface like that wood unless it's sanded and sealed though. Hope it helps in any future projects

I am actually doing the same thing, had it on my bench for a while waiting for a case design I like. In addition to 12V,3V and 5V I also need adjustable as well. But I am using a 1500W DC-DC booster 10V-60V IN and 12-90V out and 30AMP Max. SInce I need from time to time 48V, 60V to test electric mower boards. I have a 1500W 12V PSU that has a rail leaking so it no longer works on PC.

Very nice job. I think the cat is bored and is trying to tell you he's looking for a project to help with. I modified one a few years ago and included a variable CC/CV buck/boost module with digital screen and separate +/- terminal posts for adjustable output. I also have 4 separate voltage + output terminals and 1 common - terminal, all are constantly live, but I added a rotary switch to switch the boost/buck converter on/off, and the rotary switch also connects to a mini volt meter display so I can view each output terminal voltage separately, or to turn the volt meter off. I was able to keep the case, fan, input power socket, main switch as original, and I mounted all the terminals, boost/buck, volt meter, usb socket and sb/on led's and sb switch on the top panel. It took a fair bit of careful planning (ocd) but it all came out very nicely👍

The video is great. Nicely explained and with a touch of humor. Even we amateurs can learn something. I have one question, so I would like an explanation. Why are you using a 10W and 47R resistor (for voltage stabilization)?

@Sorin_DIY Ай бұрын

Hi. The power supply needs to detect a load always connected, otherwise the outputs will not be stable, or it may turn off. the ceramic resistor + volt/ammeter display + the fan will create a load always connected.
