For a future revision, I would suggest looking at using an ATX breakout board and preserving the ATX connector for the power supply. I've built a few of these ATX bench supplies now, and they don't last long. If you can get it setup to allow you to connect any ATX power supply using the built-in ATX connector, it makes swapping out a failed power supply very easy, not to mention saving the steps of prepping the power supply. Also, if you are using PrusaSlicer, you can setup a layer change to to print the top layer of the labels with a different color filament. The print will pause and allow you to change filaments manually. That should work on most modern 3D printers and give you very crisp lettering in a contrasting color. I love the way you have the panel laid out, and the use of lots of fuses. Very well done! I'm going to have to give this one a shot, though I may add a breakout board into the box if there is room ... or remix it to give it some room ...

I like the little touch with the hummer !

For those thinking that the blue wire (-12v) could be used to make a 24v output, be mindful of the -12v current rating. Many are only rated for 0.5A on that line. Many projects that require 24v would also require more current.

This is a really nice build! A great way to use up an ATX power supply that may be lying around! The only comment I'd make, and this is more for the novices first getting into electronics, is that buck/boost converter may prove to be a bit "noisy" for someone doing radio/RF projects, and that's where a linear power supply becomes important, but for most people and those starting - this is a great first power supply! Great job!

Very nice! I happen to have a spare power supply and I have honestly not thought about doing this with it! I will probably do my own version for what I know I will need. Thanks for a cool video!

Such a good job! And two fully working versions, top-mounted and box-type, perfect.

awesome project! The smooth music and intense hammering really ties it together

BANG BANG BANG!!! LOVE IT! This is a great project, thanks for this, need to build one of these for my Bench.

Terrific project. I will definitely be making one with a spare spare SFX 650W power supply. I will make a few modifications in the case design, planning to use the RK6006 DC buck converter and use Wagos replace the huge ferrules. Thank you very much for sharing, you design is the best I have seen.

Well, was thinking about buying a lab bench power supply, but this could be a nice project as well! Thanks for showing. If i can do it for less than the cost of a lab bench, i will try this 👍.

Ordered my parts Today, thank you!! Will update your Thingaverse Page with the Build Images!!!

Man, you were WAILING on those 3d prints! I'm surprised it didn't break! lmao

very easy to understand show scheme throughout this video, thanks a lot !

WOW! This is first time I see a nice looking and working thing 😍😍

Excellent job and top quality, thanks for sharing

Excelente trabalho ! Parabéns!

I built a similar thing, both items I used costing very little on Ali, one was a ATX PSU kit that you simply plugged the 24 pin plug into providing 4 fused outputs with terminals, the other was a variable voltage convertor with a simple LED screen which I hooked into one of the two 12v outputs and wired it into the 12v's terminals so I can get a steady variable pretty stable voltage from just under 1v to 12v. Think both items cost me about £4 plus a used ATX power supply, fitted it all into a plastic tub for convenience and use it all the time for just about everything.

Good build. We shared this video on our homemade tools forum this week 😎

2:16 - those "crimped" cables ;_; These are done so bad, I`m just amazed by it. You "crimped" like few mm of cables and the rest of ferrule is just empty and don't hold cable inside - remove more insulation, you can twist them a little bit and make them even exit ferrule, so you can cut them afterwards - you will achieve much better connection. Still, you shouldn't put so many cables inside 1 ferrule, but in some DIY it's the best option if done correctly.

My new favorite channel! Loved the video. Looking forward to more of your creations

Well done sir, a great video and great design. I also like the music too!!

Great idea, nice looking project.

Awesome project. We’ll detailed and explained.

Thats looks great mate. I am going to make one of my own now, cheers

If you mount it in a surface, I would recommend flip covers for the ports to keep trash and dust out of them.

Lovely build.

What Gauge Wire did you used for the ports on the back of the 3d printed faceplate?

Закрепить "барашками" - это гениально! Но работать будет не долго - нет СИНЕЙ ИЗОЛЕНТЫ !

Thanks for sharing! Greetings from México!

Obra de arte!

Teşekkürler çok temiz bir işçilik Türkye İzmirden sevgiler

Nice! 25 year electronics engineer here: In future videos I suggest the DC converting rombulous max. As it’s capable of maintaining a dual phase, single hertz, rectifier. Unlike popular belief, it acts as an inverter when power supply is in demand, or rather, not in demand from rombulous max. Can’t go wrong with it

Interesting projects, live this philosophy Thanks & regards Jean-François

Great Jon turned out wonderful cheers!

Nice build.I like it.

Классная задумка!

Nice build 👍

Very cool, I have ordered the parts can’t wait to put it together

Pretty good...Pretty damn good lads !

Perfect work, just super duper.

Perfect work👍🏻👍🏻👍🏻♥️

Very nice video. can anyone tell me what is the power consumption of the old ATX power supply (of course, without connecting any load to it), e.g. just the fan and parasitic consumption.

This is awesome dude! Good work!

1:20 What are you building the resistor for in? P.S.: Found the answer in a lower post ... but would be nice to have that explnanation directly in the video ;)

I made a very basic version of this a couple of years ago, using the same buck-converter, and on old router case. It has been really useful, but yours would be so much better. Thank you.

Молодец. Отличная работа. И сам процесс сборки интересен! Продолжай в том же духе!

Un proyecto maravilloso 😍, su trabajo impoluto y muchas gracias por los archivos

Nice Work..thx

terimakasih tutor nya pa, sangat bermanfaat 👍👍🤗🤗

Why you put a resistor 8 ohm 50 w between ground and hot line pin?🌹

I love your video editing

Thats awesome.

good idea but it will be better if you can just have all PSU connector connect to the socket than do the conversion with in the controller box, this way its modular design, it will be easier for others to adapt to this design also will be a simple fix when PSU breaks down by just swap it out, without the need to re solder all custom connectors

I was about to buy mytself a power supply. This is wayy more cooler!

La fuente regulable más fácil, siempre y linda que e visto

Very nice.. do you have a wiring diagram for people to refer back to?

Awesome 👍

Line up the lettering on the fuse holders for goodness sake! All that nice work, cleverly done 👍

i like your video. But why use of the 8 ohm 50W resistor connected to a +5V wire and a ground?

Nice to see someone using ferrules and properly covered spade connectors, instead of soldering everything together. Looks good👍

for the resister does it matter what black wire or red you take ?

I love the interface, just wish the design was all in one so no separate psu hanging out the back

Very good job. Keep it up👌👌👌👌

Nice video, thanks :)

Keep in mind that PSUs from 2000-s - ones that possibly will become a choice due to possibility to get them from discontinued office PCs for free - most likely will be cheap ones with single DC voltage rail for all voltages in PSU. These PSUs are supposed to work in particular load range. Going outside load limit will noticeably change voltage level and add noise in other voltage outputs. Thus increased load in +12V rail may and will cause failures for components connected to +3.3V and +5V rails due to voltage increase with load raising at +12V rail :) As insult on injury - these units often doesn't have functional OVP and OCP as well.

I personally wouldn't use female power jack, it is made to receive power, not to provide it, therefore it's designed in a way that's making it very easy to short positive and negative when manipulating with something conductive like screwdriver near the power supply. To your credit, it's at least protected with fuse, but still, there are better alternatives...

It's amazing !!! Thx i must do it :)

After buying all those connectors and components, was it any cheaper than a low-end purpose-built power supply?

I made that 2 years ago, it is super cool. I just wanted to say, you dont need fuses. Pc power supply will turn off automaticaly if you short circuit it or overload it.

Aluminum house resistor is that important and must had if we make this power supply .and one more where use black and red wire.. sorry ..still learning..btw good content..thanks

This is a nice idea but remember, the buck-boost converter for the variable power side is not isolated and flips the polarity of the DC on its output, effectively making it a *negative* power supply relative to the others. If you try to use, say the 5V and 24V from the adjustable side, and connect the grounds together, you are going to have a bad time. As long as you don't try and use the left and right sides together it'll work fine. Or, use power from the right side and use the variable side as a negative supply will also work.

I like your presentation video

Generally I despise pantomime videos, but I enjoyed this one. Thanks.

yeah, i like the most the rubber hummer work :)

olala is very gooooood 😍

(Beautiful music playing) *Bam* *Bam* *Bam* *Bam**Bam*

I'm in the process of printing and building my own customized version of your power supply. Thank you for the print files, supply links, and the video! Sorry for the ignorant question, but what is the purpose of the resistor added to the 5v side?

Excelente proyecto y ejecución. Muy prolijo. Te felicito y te agradezco por compartir tus proyectos a la comunidad. Todos los aportes suman, más aún si se ejecutan de esta manera. Saludos cordiales desde Buenos Aires, Argentina

I like how the video is all calm and peaceful ASMR-like and then "POW POW POW" with the hammer 🤣

The amount spent for fabrication and aceesories and displaymodule all work out high for which one can buy a adjustable power supply unit.

Acts very careful being cautious. Then proceeds to pull out rubber mallet and beat the living neck out them plastic parts lol

Nice one, what printer i need to buy to make such things?

Genial, Danke !

Hola, gracias por todo, una pregunta, por que conectas la resistencia de aluminio a 5 volts? Cual es su función? 😅

Nice job! The video is a joy to watch because of your editing. I especially like how you laid out the components on that black cardboard, making it clear how things are to be put together. One question though: what is the purpose of the 8 ohm 50W resistor? It is connected to a +5V wire and a ground, correct? Thanks.

Wiih keren❤❤❤

What resistor should i use for a 300 W power supply?

3:12 gently pushing it 3:16 S M A S H

I like it.👍👍🙏🙏

nice

dude! you make videos better than some people with thousands of subsribers! love it!

What's the use of resistor load ? And why did you connect it to 5v ??

Where does the terminal strip get mounted?

Хорошо придумали , лицевая панель отлично выполнена. Я купил бы у вас несколько панелей без навесного. Как вы на это смотрите. Приморский край.

Hi. Thanx for intuitive video. Just one question: are 3.3v, 5v and 12v outputs sharing a single ground? So you can only use one of them at a time? My psu has 3 12v rails @18a each. I want my 3.3v, 5v and 12v to have their own ground posts so i can use them simultaneously. Of course staying within amp limits. Also I want to use all 3 12v rails. They are there on the psu, meant to be used. It should give me more output options. Am I missing something?

One shunt for measuring amperes, on the main graund , as well update version ?!

What is the aluminum housed resistor doing?

Hi, the resistor (50w 8 ohm) whats is the purpose of use it?

what is the Resistors for?
