- 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.

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!
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 :^)
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 🙂
"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."
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).
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.
A professional giving a professional project presentation. Thank you, Sir, for giving perfectly precise information.
Very informative and even more entertaining, thank you and your lovely assistant for producing this video. 😻
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!
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!
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!
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.
Connect the fan between +12 and +5 V . Check and choose polarity 7V cc . I like your assistant !
Very clever!
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.
Well done. I think I will make one for myself. Thanks for making this video!
Real DIY King! Amazing videos sir!
Thanks for sharing this video and information. I appreciate your thoughts and advice.
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 👍👍
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.
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
very nice work man , thanks for sharing !
Nicely done!
Nice bit of work And looks great.
Awesome project 👏🏻👏🏻👏🏻
Ai urcat in topul CZcamsrilor mei preferati :D Keep up the good work!
Very nice !! Pro looking !! Love the cabinet work too !!
Good work as always, respect from India 👌☺️
Nice video Sorin - clear instructions and explanations. Funny too - your cat wants to help.
Great project! Congratulations!
My cat looks exactly as your does, she a real character. Awesome video thanks for the hard work.
One of the nicest looking computer power supply conversions I've seen, good job.
Nice power supply conversion!
I enjoyed, so I subscribed. Can't wait to start binge watching your content.
Great video as always, keep it up
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.
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.
Nice looking build. Hope it got your supervisors approval😎
You mean the cat?
@@SeeFreeTV of course😎
Nicely explained in details, seems to be accurate, for electronic experiments, thanks
Thank you for the very good instructional video with no faffing about and I loved your cat helping you !!
Nice pwersupplay, beautiful presentation. GREAT.
Thanks for the video Mr. Sorin
Sorin loves his ATX PSU to Bench PSU conversions lol
Very good job, bro👍
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
Nice project
Finally a video!!! welcome back.
I too enjoyed both the technical aspect and the humerus one. El gato will steel the whole show he is quite the actor!😃
That's beautiful power supply.
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.
Your cat and yourself are funny Sorin.
Nice job.
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 power supply. Beautiful cat.😊
Thank you for including your mischievous assistant ! !
nice work ! thank you ❤
Great video. I love your humour, and of course your cat!
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.
Realy funny and nice design.
i like your soldering iron.
Sempre bravo ed esauriente.👍👍
That was super entertaining to watch! I love the cat helping as well lol 🤣
Thank you so much sir, it was beyond helpful. And also lovely cat.
Indeed computer PSU are very handy, i keep couple of them for the purpose of auxiliary supply
Regards
Jean-François
Interesting tutorial DIY video.. Enjoying to Detailed work.. Great. Thanks
hi Sorin what a simple and compact video.....! Add the connection diagram too
Thank you
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.
thank you very much for good guidance sir..
great video. I needed only 12V so I left only that output
Great job ! And, I LOVE the cat.
Due to short circuit protection -12 vots handels only 0.5 amp current if you exceed this current SMPS will turn off.
For this you can bypass the protection circuit and use its full power even in +12 -12 rail.
How would one find the circuit in order to bypass it?
@@damyanstoyanov1830 wires going to voltage to regulator IC or main IC by resistor.
It depends bro every circuit is different try finding video on CZcams for your model or same looking pcb board
DONE GREAT JOB.& NICE EXPLANATION.
Bravo Sorin frumos proiect, tare amuzanta si zapacita e pisica ta 😅
THANK FOR THIS VIDEO, GOOD JOB. VERY USEFULL, VERY NICE
I LOVE that you included your cat in this. 😁😍🤣🤣
Very good idea thanks bro good work
Nice video!
People:- The high voltage stored by the power supply capacitor can shock you 💀
Electroboom:- I know what can shock you better 🍷😎💀
thank you, education and fun.. love that cute cat 🥰
Good video and nice cat. Thanks for sharing.
nice sharing
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👍

Nice job
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)?
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.
New subscriber always watching your videos ❤❤❤thanks i like it most😊
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.
Nice job.
Awsome. Very interesting video. Thanks. Bro.
AHHH THE MAN IS BACK AGAIN 👏👏👏
Watching your video from Bangladesh. Actually i watch your all video
Great Man, Subscribed your Channel
Great tutorial... I love the cat🐱
Thanks its very cool
Your cat is cute, Me and my wife have a 30 pound monster Tabby, She runs the House, Great power supply Build.
Brilliant !!!
Excellent presentation! I do have a question...what are the maximum number of amps it can produce and is there anyway to wire it so it would produce the full 19 amps? Thank you!
Hi. Each output of a PC power supply (3.3V, 5V, 12V) has a specified maximum current. if you connect the internal wires directly to the binding posts, each output will deliver its maximum current (if the power supply doesn't have any problems). but if you redirect an output, let's say the 12V output, through a DC converter to adjust the voltage and current, then the maximum current will depend on the type of the converter, the adjusted voltage and the efficiency.
Chiar cautam o sursa ieftina. Bv, ms
Came for the cat but also learned how to make a power supply.
So cool 🥰‼️
awesome video . I don't fully understand everything but hope fully we can ask for some tips
Hello Hi Bro I like all your videos very much and recently. I am a subscriber on your CZcams, I like all your videos and they are also useful.
