- 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.
A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.

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 :^)
Thank you for taking the time to do this. Just made my own. Now be able to use it to power my other DIY projects (RSU, magnetic stirrer, photoetch shaker etc, etc).
Humorous, clear, straight-to-the-point with some very nice ideas here. Thanks for posting this. I have all the parts to make one of these but keep putting it off. This video may inspire me to get back to work on it. Great work!
Just found your channel and just want to say I love your style, honesty and self depreciation is an extremely rare thing on YT, and everywhere else nowadays come to mention it. The added humor is a bonus that has now made me a fan and subscriber. Please keep doing what you do and thank you for your excellent content
Ah... Fellow subscriber, then; despite this is the very first his video that I seen, I love his style etc and then, subscribed 🙂
A professional giving a professional project presentation. Thank you, Sir, for giving perfectly precise information.
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.
"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."
Very informative and even more entertaining, thank you and your lovely assistant for producing this video. 😻
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.
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!
You have prompted me to look into doing something similar with one of my old PC power supplies, good work. Love your feline helper too, every electronics channel should have one.
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
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!
Nice video! It's always nice to watch someone who knows what they are doing. Since I am not one of them, I am now convinced to just buy a power supply instead.
Very nice work! I can't wait to start my own power supply (requesting the parts now...). And I love your cat ;-)
And I really love that you use the 'old' power supply case, so we don't have to make a new one 👍👍
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
Excellent tip!
Well done. I think I will make one for myself. Thanks for making this video!
I built exactly a same bench power supply. But I also added a relay and switch before the variable power output so its easier to set the required voltage before hand and then switch On the load.
Real DIY King! Amazing videos sir!
One of the nicest looking computer power supply conversions I've seen, good job.
Connect the fan between +12 and +5 V . Check and choose polarity 7V cc . I like your assistant !
Very clever!
Thanks for sharing this video and information. I appreciate your thoughts and advice.
Very nice !! Pro looking !! Love the cabinet work too !!
My cat looks exactly as your does, she a real character. Awesome video thanks for the hard work.
Nice video Sorin - clear instructions and explanations. Funny too - your cat wants to help.
Finally a video!!! welcome back.
Great video, I've been watching this a few times because I have an old computer with an ATX power supply, and this video was a great reference. I'm almost done now, I just wanted to add a warning to anybody out there that the heat sinks on these models may not be grounded and while it didn't kill me, was a big surprise
nie byłeś wystarczająco wilgotny
I enjoyed, so I subscribed. Can't wait to start binge watching your content.
The simplicity of the narration and the presentation make this familiar subject enjoyable. I think it's worth the holy bible for novices like me. Thank you Sorin.
very nice work man , thanks for sharing !
Thank you for the very good instructional video with no faffing about and I loved your cat helping you !!
Nice bit of work And looks great.
Nice power supply conversion!
Awesome project 👏🏻👏🏻👏🏻
Great project! Congratulations!
Nicely done!
Nice pwersupplay, beautiful presentation. GREAT.
Ai urcat in topul RUclipsrilor mei preferati :D Keep up the good work!
Good work as always, respect from India 👌☺️
Great video as always, keep it up
Thanks for the video Mr. Sorin
As always, I love your cat. :) I've seen your other power supply conversions and I want to make one, but I have a decent sized bench-top power supply already, plus two smaller ones. I love building stuff though. I might make this one just to be doing it.
Es excelente este video y mas aun porque se ve la evolución de tus trabajos...este tema las fuentes de laboratorio caseras son FUNDAMENTALES...ojala sigas creando mas modelos... saludos desde Argentina Bs As
Nicely explained in details, seems to be accurate, for electronic experiments, thanks
Nice looking build. Hope it got your supervisors approval😎
You mean the cat?
@@SeeFreeTV of course😎
I love this idea. I have an unused pc power supply... I might attempt a similar mod. Very cool. Also, love the shots of your cat!
Great project! Enjoyed the cat!
Very good job, bro👍
Realy funny and nice design.
i like your soldering iron.
Great video. I love your humour, and of course your cat!
Very good power supply. Beautiful cat.😊
I too enjoyed both the technical aspect and the humerus one. El gato will steel the whole show he is quite the actor!😃
Your cat and yourself are funny Sorin.
Nice job.
Excellent video - entertaining and easy to follow. I have a newer 700W power supply from a tower PC I no longer use. It comes with a slew of wire connectors so I am hoping to make a companion pox that will interface with it somehow instead of modifying it like you have done.
AHHH THE MAN IS BACK AGAIN 👏👏👏
That's beautiful power supply.
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.
Correct.
No.. I make 24v from -12v, test curent load and I got 8a drop to 22v in full load amplifier tpa3116..
In his test with that car light bulb it is proved that it can exceed well over 3amps, probably more.......
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.
Thank you for including your mischievous assistant ! !
Thank you so much sir, it was beyond helpful. And also lovely cat.
That was super entertaining to watch! I love the cat helping as well lol 🤣
Great job ! And, I LOVE the cat.
Interesting tutorial DIY video.. Enjoying to Detailed work.. Great. Thanks
nice work ! thank you ❤
Nice project
Indeed computer PSU are very handy, i keep couple of them for the purpose of auxiliary supply
Regards
Jean-François
Sorin loves his ATX PSU to Bench PSU conversions lol
hi Sorin what a simple and compact video.....! Add the connection diagram too
Thank you
Sempre bravo ed esauriente.👍👍
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.
DONE GREAT JOB.& NICE EXPLANATION.
Good video and nice cat. Thanks for sharing.
THANK FOR THIS VIDEO, GOOD JOB. VERY USEFULL, VERY NICE
Nice video!
Very good idea thanks bro good work
thank you, education and fun.. love that cute cat 🥰
thank you very much for good guidance sir..
I LOVE that you included your cat in this. 😁😍🤣🤣
great video. I needed only 12V so I left only that output
Nice job
Awsome. Very interesting video. Thanks. Bro.
