The best video I have seen as of yet explaining properly all of the functions of all of the color coding wires. Thanks for a good explanation.
Nicely done Sorin. You have given me many good ideas for my next ATX conversion project: the rotary switch and volt/amp meter. Very good-looking finished product you can be proud of.Tip: A good way to cut square holes in the steel case is to use a cold chisel. One or two blows will cut a perfect corner through the steel case.Thanks for all your effort in producing this video.
This is by far the best looking ATX PSU conversion I've ever seen. Well done my dude.
Since the rotary selector switch is merely there to select the input of the Volt/Amp meter, and you still retain power on 3.3/5/12V rails regardless of the switch's position (which is very useful FYI), I geuss I do have the "same level of genius", though, not in the bad light you painted it.
You however, neither seem to know why that would be useful, nor that it is an inherent trait of an ATX switching PSU. Assuming you know what the "switching" part of the description entails.
If you are going to leave salty comments, make sure you understand the topic beforehand. Unless it is you're goal to look like a fool. If it was, - success!
Also, this was a 7 month old comment.
Oh, and please work on your grammar, I almost had a stroke trying to read your comment. English is not my primary language either, so that's no excuse...
@Jilvir Paeste apparently you suck at both.
I hace a doubt, it seems that my source atx doesn't have the fuse included, if I wanted to add it, where should I put it? Will be right if I connect it in series with my switch of stand by or where? If anyone can help me I'll be so thankful.
Best of the many ATX conversions on CZcams! - good craftsmanship and lots of reasoning given. Thank you - I'll do this project as soon as I can get a cat :) Not sure about the heat transfer through the film of 2 part adhesive though.
The side hole makes a nice home for my cat's paw while I'm working. I watch his little face light up... so cute.
Great video man!

@@estebanmartinez9143 You... replied to a comment about a cat...
@@gtr_guns673 fuse your cat
really cool finish, you made me think to rebuild my lab psu made with ATX as well. I used 2 to get 24 V, and added a regulation circuit for regulated output ( max 2A) .
Did you just make two supplies and then run them in series?
Why not use a boost/buck converter to 2/3 12v wires and use that
@@voyagertechnologies ..buck/boost makes things worst if u consider limited noise tolerance ..you can calculate the tolerances hit in every circuit you connected ones..
@@jhonnyginting8985 Seriously you gonna complain about noice when the guys alternative is connecting 2 psu's in series! Ever used an old psu, he certainly aint buying bequeit gold rated supply
FYI, Current regulation is quite easy if the voltage is fixed. All you need is a power transistor and a single low current resistor(and a spec sheet to learn the gain of the transistor) :P
I build this project using plexiglass someone threw away, and an old computer a friend gave me that no longer worked. It works great. Thank you for the great video, and information...
7:50 comes a self-welding tape just for these cases

What will be the power consumption, if we only use one 12V supply from PSU?
Will it be same as using it completely?
Simply amazing! I have to do this to an old PSU one day. One of the best tutorials - your channel deserves so much more love.
Thank you!

This video gives me some ideas. I must consider them. I have a few old but working power supplies that I have no current use for (for older computers) but I know a purpose I could use them for if I can get out the 12V and 5V. Thank you.
Nice job, I need a desk top power supply like that and I have several old PC power supplies that I can use for this.
I have thought about doing this many times over the years, never quite got around to it. You have encouraged me to just build one. 😎
Same here! I subscribed once the cat had passed! Lovely clear instructions and explanation as to WHY you did things a certain way. I now plan to make my own from an old PC PSU.... now to find an old PC PSU... :D
dont forget to find a cat
I appreciate the level of detail you go into.

This video was surprising well detailed and informative compared to others I've seen, well done! Will definitely be building one myself in the future...
Fantastic! I thought that the video was really well produced and your project is awesome.
Thank you, Sorin.
Suggestions: USB signal , Short USB D+ and D-- Signal , It will increase the charge current when you charge your phone.
how about using USB-C connector on a fast charger?

Great informative video Sorin, thank you for sharing. I've been wanting to make one for the longest time. I think you have inspired me to do so.
Clear, informative and humorous. I really liked this vid, thanks for sharing Sorin!
Best DIY power supply mod i've seen so far :)
Could you include the parts list in the video description ?
hi. thanx for watching. I have bought all the parts from my local hardware store, so unfortunately I can't give you links where to find them. but I've included the parts list in the video description. you can buy them locally, or search them on aliexpress or other sites.
Thumbs up for the 'cat pass' 😆! Informational video!
Congrats to your talents for being with us today and the future THANKS for sharing your thoughts and experiences.
Excellent job. Now I know what my next project is going to be. Thanks for sharing.
4:06 "let the cat pass" okay subscribed
hhhhhhh
I have built a power supply exactly like yours,now I have to find a cat to finish the project.thanks
hahaha
Perfect! Had a little jolt of education there. First time seeing the current reading independent from the voltage source.. could have broken some misconceptions fast when I was in school.. So you have to just be alert of the max current ratings.. the problem might be that you wouldn't be able to tell what you are doing to a single rail when you are using more than one at a time.. but I agree with the practical boundaries.. I would also not likely need more than that.
Dude you're the best. I love your passion and knowledge in what you are doing. Keep up the good work.
I love how you let the cat pass
"Let the cat pass" hahaha. Great video! Subscribed!
"Just don't think you're finger in there"
I agree!!
Thank you for this video,, It is so great to watch a video that is not high speed and nothing is being said no explanations. Well Done !! once again Thank you
That's brilliant, great project for me to tackle
Thanks for sharing
very good quality, thanks for sharing.
Well done. The best DIY bench power supply I've seen.
yep, that sounds like a great idea.
Seriously though, if you are really short on space, you can power something kind of decent with either a buck or a boost converter running of USB.
i build digital upgrades for 1950s model trains. I have a basement lab with 4 benches. I am using train transformers for my test stations, but this idea is outstanding, I have several power supplies from failed devices, I should check them for power and re-purpose them as bench power supplies., I like the digital meters and switches. The variable component may use a pot or a transformer lever with a knob in stead. This is an inspiring project for me to try, thank you D

same here, I nearly choked on my beer when he said that. Fantastic.
i want to charge my car bettery with computer power suply. But in power suply there is a yellow color wire having voltage is 12v thats ok,,, but ampere is low as about 1ampere to 2ampere only (which is not suffient to charge my car bettery). My problem is that how to increase the amperage of (yellow 12v wire) so that it charge my bettery easily.
regds,
thanks. plz reply in detail to solve my problem
Well nice to see good quality content from one of my "people" ;-)
Cheers
very skilled at what you do. You made this project look easy.
I made one that I can adjust the voltage and limit the current by using this kind of psu.. max 10 amps and 22-23 volts. and also I added stabil voltage outputs (3.3v, 5v, 12v)(did not use a rotary switch but seperated 3 red+1black banana sockets). and put exact the same voltmeter-ammeter you used. it was so good , then I gave it to my friend. I have two more psu's that I dont use them for pc's so I'm gonna add an extra usb output and make a better one.

"Let the Cat pass" - fantastic.
I had to use a rabbit for this step. It worked fine.
Most underrated comment.
That is a brilliant job, you are a clever lad, thank you for sharing.
I regret that I already read from the comments when the Cat actually passes while watching the video. LOL still made my day. Nice!!!!!
I bet the cat left to avoid the shrinking tube
No, I think it was the music.

Yes, I enjoyed it and I be subscribe!
Very nice and good
Excellent video, well explained and a brilliant project too. Well done Brother, I have subscribed. Much love from UK, Ken.
Best guide out there for this hobbyist essential kit
You should Always let the CAT pass...LOL...thanks MAN
I followed up to about the nine minute mark ... then began to shuffle dance and missed the rest. Dang!
(I did thumb up and subscribe!)
Shrinking Tube!!! Lol, Great video! I've been looking to do this for a while but I was hesitant with a bunch of questions.. your video answered all of them. Great editing and great music! ✌️👊
The best vieo I've seen on converting atx psu. Concise, precise
"let the cat pass"

Guys I really need help with this project, so I started building it from scratch, got me a good 500W power supply unit from the used computers store, I think it was really cheap.
I disassembled it, cut the wires as the video shows to work with them easily... and got the other parts from the electronics store, the thing is... I was trying to do the first holes with the hand drill but my cat just keeps standing there, staring and judging every movement I make, it won't pass... I have tried everything... from food to scratches and it won't move from the project table... I'm stuck at this, you guys can help me pleaseeee? I'm desperate to finish this power supply, but my cat won't PASSSS! HELP!
cat.exe has crashed, restart cat.exe
Splendid. Great camera work. Very helpful. Kitty was nice touch.
I like it. Simple and functional. Also well done. Greetings from Austria to Romania.
u have sub from me, so simple DIY !
Ai de plm, un roman 😂 acel "Sorin" la inceput te-a dat de gol. Respect! Also a great video, very informative and well structured!
Absolutely brilliant! Awesome job! :)
easy and effective! great IDEA. Bravo!
I've got an idea: Would it be possible to connect the built-in fan as the dummy load so the power supply turns on?! Would this be enough load?
hi. that is a good idea. for this power supply it will work. but the fan is consuming very little current and there are some power supplies which may need a bigger load. also you need to solder a connector to the yellow and black wires, so you can easily remove the fan cover if you need to reopen the power supply.
some modern PSUs have variable voltage output for the fan, so the fan's speed will variate depending on the load or PSU temperature. if you connect the fan to the 12V output, it will ad a load, but the fan will always work on maximum speed.
@@Sorin_DIYhello sir I’m a student I used this like my school project I followed all your step but I have a problem my lab psu turn for a second and then goes off i mean like screen voltage /amper it goes off when I give the current help me please
Felicitari, super ....

Shit, I have no cat! : (
Now I can't cut that hole!!!
So my project will fail if i don't let the cat pass?
costara yea
Yea costara
This looks amazing! Keep up the good work!!
Hey dude! You are awesome! Thank you for the idea!
Hi! This PSU looks really good! However, if you have three sets of banana plugs/binding posts (3V3, 5V, 12V) - why do you need the rotary switch? I would think that when you make these, you either have the rotary switch for selecting voltage and one set of binding posts, OR you do it a bit simpler with only the three sets of binding posts (even simpler is one red for the different voltages and one common ground).
I think the rotary switch just changes which output the meter displays.
he can't directly connect output high current to rotary switch because its sparks and i think after 5 time rotating switch,its messed up and die.
so if no rotaty switch so ho can remove anothers banana post during use one? i mean inorder that shows volt and current of just one post?
just one other concept remains :
use really instead of direct wirin to rotary to pervent spark and damage( anyway its randomly shot down unit becausr of china responsibility to probife minimums!😁
Tools required:
1. Soldering iron
2. Cat
3. EDM
4. Cutting Pliers
Thank you for being so concise and detailed
You did an awesome job on this!
So the cat pass was necessary to activate this power supply :-D
THATS FRICKIN RIGHT
It is necessary exorcism rite to shun out fault demons.
very meticulous work.
Hello Friend! Watch my video!
czcams.com/video/Jo6KEs3t3To/video.html
Nice! I'm about to build my own PC PSU desk power suply. I doubt it'll turn out as nice as this but we'll see.
Wow what a video, after 6 years i see this, its amazing ❤💚💙🙏🙏🙏
lmao LET THE CAT PASS!. What would you charge just to build one of these Id buy one from you!
Bil Paranormal Investigator Build your own,its a fun project. Just don't cramp everything in one box like he did, make a seperate smaller box with all the wires going inside that box,much easier and safer
me too $$$
The whole point of DIY is if you do it YOURSELF. You can buy a variable power supply for less than $70(won't be very good tho). You paying him to build you one is stupid and beyond me, pay a cheap chinease company and get it off shelves? Build it, that's what i would suggest but if you cant/don't then buy it
@@voyagertechnologies Yes this is the whole point of DIY. But not everyone has all the tools needed and they may be lacking the skills or knowledge to make something their self.
@@AnthonyGoodley You do realise these are easily available on market, the whole point this video exists is to make it yoursemf cheaper, im no expert and i have completed this project aswell. If you cant even cut wires and connect them to a metal plug, you dont need a variable lab bench supply
Always let the cat pass 🐱
Looks like a very clean build!
I've got one of these spot welders, but no battery so this was nice to learn and hopefully can get mine to work also.

Cool project but my friend is dead from AC :(
:(
Just need a few more bits, then gonna get to making one myself. Nice concept
Absolutely brilliant Job! Greetings from Venezuela.
Nice video, subbed. But that background music takes away from actually hearing you. Hope you get rid of the music
Second that the background music needs to go
Can you sell this to me ;)
Nice build. I like that you did things safely. Probably could have omitted the main AC power input switch since it has low standby current draw when switched off. I've done this, but beware, some of the cheap chinese made PSU's are ground referenced to mains. In the last one I used, the case was live at about 90v AC with no apparent shorts. I trashed it as it immediately tripped GFCI outlet protectors when turned on. Better PSU's have better isolation.
Excellent work, very clean very neat, is a professional job.
I hope that others looking at this video don't follow his example of how he's soldering the wiring. It is never acceptable to apply solder to the tip and then to transfer it to the wire connection. You must heat the wire connection with the soldering iron tip then add solder. The method shown will result in what we call "cold solder joints" and could become intermittent over time.
