You need a rotary tool! I don't know how I survived so long without one. Really good for cutting all those square cut outs with a small cut-off wheel.
very well explained, to build with very simple means, unfortunately I can only give my thumbs up once, you would have earned 10 times.
BEAUTIFUL WORK ! SUPER.
A mais bonita que vi até agora!
A superb job.well done sir.
It's simplier than the others, because you still use the housing, I'll probably imitate this, TY! Sir!
i have never seen such a perfect video and the perfect work that you've done
Par Excellent! Very well Explained! Thank You.
Melhor video de montagem de fonte k já vi
Good repurposing of the SMPS / ATx power supply
OMG! you are a dam Genius !!!
You have layout this video perfectly, thank you- young man!
I've had one of those rotary switches lying around for donkey's years, now I know what to do with it.
I had one but I broke it when trying to solder I melted the plastic and some connectors become loos tryed to melt them back can't put it together :(
I was like not wort my time I buy a new one
Why do you need rotary switch if in any case every plug shows it's own voltage. Just connect bananas into plug you need an here it is, voltage that you wanted.
Excelente!
Buen video amigo, el selector de voltaje que colocaste, no conmuta el voltaje de salida en las diferentes borneras, por lo que puedes estar usando la salida de 12 voltios, y estar marcando 5 en el voltimetro. De todas formas la fuente te quedó excelente, gracias por compartir. Good video friend, the voltage selector that you placed, does not switch the output voltage on the different terminals, so you can be using the 12 volt output, and be dialing 5 on the voltmeter. Anyway the font was excellent for you, thanks for sharing.
Porque si mira bien lo schema grafico del circuito il potensiometro no es collegato bien,es collegato a la entrada e no a la uscita.....solo al voltmeter....
Awesome job, did u publish a parts list? With numbers?
Valeu!
Grato!
Muito show!
Does something change if instead of the 20 ohm resistor I take the 18 one?
Essa fonte é boa e ficou perfeito
Muy buen trabajo, muy prolijo y me gustó el color.👍👍👍👍
sehr gut erklärt, mit ganz einfachen Mitteln nachzubauen, ich kann leider nur einmal Daumen hoch geben, Du hättest 10 mal verdient.
Dear friend
In your item description of the parts to be used you describe 6) 10W 10Ohm Ceramic Resistors x2.
In the shown vid and 10W 20 Ohm Ceramic Resistors x2,
Which right should I use ???
Good Job. Identical project to "Sorin - DIY Electrical Nerd".
It's a copy from sorin
Great job!👍
Thanks
im the 6666 like! :D incredible video! thanks man (from Argentina!)

your video is understood. the explanation is clear, however I would like to know the small circuit that you have removed from the power supply unit
(3mn 10s of the video) and you soldered to the input of the power supply (8mn 39s) what is it called? If not soldering this circuit, can the power supply unit give the same results? And what is its role in everything you have done. Thank you
Very nice
Buena aportación, pero si comentásemos más el video mejor. Gracias. Good contribution, but if we discussed the video better. Thank you
Perfect job done
thank´s for your video and time, ihave some questions if you can tell me: wich is the need of the two resistors of 10w. and the circuit with the toroid and capacitor you welded in the input, and at last why didn´t you used the blue wire with -12v ? thank you very much again, regards.
you have made a very nice job of this psu neat & tidy. i love the paint job,it really suits the unit. well done
telstar vision Thank you 👍🏼
Gran trabajo, yo me hice una con salidas USB de 5v, una de 3,3, otra de 12 y otra regulada de 34v, un saludo.
Oye, sabes si tiene desventajas a la hora de diagnosticar ?
@@NovatoWTF Hola, solo date cuenta que es una fuente de voltajes que te haces en casa y solo puedes confiar en que el fabricante de la fuente haya hecho sus mediciones. Por lo consiguiente, no creo que su huso sea profesional, solo para las chapuzas típicas de kuñados.
Espero te sirva de ayuda mi respuesta, un saludo.
Very nice choice of color! -- Relatively neutral without being boring. ;-)
Two little things I would say. Your vertical power switch is upside down, and you should make it VERY clear what the knob does.
Muito bom, só falta o áudio com explicações profundas.
*EXCELENTE !* 👍👍👍 (From BRAZIL)
You did a great job!
But didn't I see a + 12 volt & -12 volt? You could have added a 24-volt option!
HI LahisTech, why you solder the black thin wire from the ampmeter to one black ground wire from the psu? thx for you answer! nice Vid + nice shemata!!!
If this was thought in my BE colleges i wouldn't be working in PSU, Finished BE book worm 😂
Simple, smart, robust and very util. If not good for you, buy a professional Lab bench power supply...
Oi amigo precisava de uma dessa sera que daria pra fazer uma dessa pra mim quanto cobraria. Para mim seria muito bom
Thank you, well done and easy to understand :)
BUT: unfortunately I can't find such a small (and affordable) volt/amp meter that supports enough current for my old ATX power supply: 3,3V*28A, 5V*30A, 12V*15A. I can hardly believe that the amp meter used in the video supports more than 10A. So be careful not to grill it by connecting too much load.
Thanks you; you can purchase it from Ebay.
Ola eu gostei
hi,
why did you connect two resistors to the 5 volt output?
Very good
Hi, can i connect 12v and 5v together and then use a DC to DC module to get more power from atx?
Good tiching karte hai 👌👍👌👌👍👍👍👌👌
@LahisTech If I wanted this to only output 12V would I still need the 10W 40Ohm resistor? I'm currently trying to get an ATX PSU to work, but it keeps switching off. I have a 10W 10Ohm resistor connected to a 5V red lead and thought I may need one on either or a 12V and 3.3V...now I'm wondering if the resistor is the wrong one.
If your power supply is newer,then theres no reason to put a load on it.Just check the pins with a multimeter its near the supposed voltage like 3.4v on 3.3v then you dont need a load
very good job my fiend thanks a lot
I through a bunch of these out with my old office computers. Really wish I'd stripped them now.
Well, yesterday I disassembled 2 computers, got 6 fans out of them, and 2 250W power supplies!
The PCs are quite old.
I'm typing this through mobile version of Chrome, and it doesn't allow to modify your comment
Da pra fazer com 120volts?
Nice presentation......
Thank you
très joli
nice it looks like a 1 to 1 copy from a 2017 video. still a nice copy.
shrunkzebra plays Thank you
Sorin diy...
Your video is very interesting
Boa noite, qual é este potenciometro ?
Hi very good tutorial and project! Can I ask you what is the purpose of the 10W 10Ohm Ceramic Resistor?
muflo71 If I have this correct, some power supplies (older?) require a constant load on the 5V rail for stability of the psu. The resistor(s) provide that. One possible alternative I ‘ve seen suggested for the load is a 5V led, which could be used as a power on indicator on the front panel, I would think.
In your project did u install a fuse? in case you the positive and negative tips touch and it causes damage to the machine
Brod... it is possible to use only one black binding post since it has already a selector?...
I'm thinking to make a project like this, but using a regulator for variable voltage and current. I should ask a few questions.
Why did you assemble 3 pieces of cables for each 3.3v, 5v and 12v outputs? To provide more current from this terminals or prevent heating up this cables?
What's the purpose of this dummy loads?
Why did you use a rotary switch? When you set it to 3.3v, 5v and 12v outputs are still active. Is it only useful for reading current of connected port?
Question: Could one use the 5vsb to power the display when you use the 3.3v? Mine dimms a lot at 3.3v, so using the 5vsb as an "external" power source for the display seems like an option.
Somebody get this guy a dremel

Hi! Your work looks like pretty good.
Can you answer me, for what we connect 2 power resisters consequnetly?
check 10.51 in the video (+5V & GND)
Thank you.
nice project, im building mine and getting many examples of how to made it. Why did you put the switch that change the volts, if they are static from each binding post. You dont need to swicht it for use the different voltage, right? or something change when you switch?
To switch the amp/voltage meter between three voltage levels. Appreciate your support.
おお！
Hi, I have a question. Why did you use 3 different ground binding posts, since you connected them together with the same ground wires? Only one common ground post wouldn't be enough?
yup, but i want it looks better with 3 separate grounds
@@LahisTechLT Oh, so i can use only one to save space, right?
@@ttibor yeah
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.
mantap om
Thank you for the quick replay.there is no connection between banana plug and rotary switch .so each plug is used for separate voltage ?can't we get 5v 12v etc from the same plug by adjusting the rotary switch . That is my doubt. Cold u please explain .I couldn't follow that part of the diagram
Sathyan P.G same question from me
Hello Lahis where can I get the diagram & parts list for this very nice compact Power Supply unit which you published on 01/24/2019; I want to make one, I have several ATX PS units, thanks.
good !!!!
Thank you
diodes on the bananas bro. polarity protection
@M. Gengo A single diode is a surprisingly effective way to incorporate reverse-polarity protection into a device's power-supply circuitry. Schottky diodes have lower forward voltage and consequently are generally a better choice than normal diodes
Great video. You are very good at this.
Thanks
I wish I was as electronic savvy as you.
EXCELENTE TRABAJO ME GUSTO
Very nice brofesser
Hola amigo donde conseguir los elementos y sus precios
Otro mudo que sabe algo de electronica !!!
great video thnks
oooh nice man thnxs
You made it upside down. Hot snot on the dummy load not a good idea. Is the current meter in line of all the outputs? You didn't set the stop on the rotary switch.
Current meter is used with ground.. ground is common for all. So it will work on all 3.3, 5 , and 12
Hi, Could you explain why you need two 10W 10Ohm Ceramic Resistors? Thanks!
I was thinking maybe it would shut itself off without it? But who knows?
I would like to know why he didn't add a 24 volt option?
He had + 12 volt and -12 volt.
The pc power supply need a cargo for give the right voltage i am not 100%
What about the short protection ? Is it disabled ?? Otherwise we won't be able to run at high amp
You have at least three blown capacitors on the board ;)
How do you know lol...you have not even try it yet...
@Neodiy,c0m: You don't have to test them to know if they are blown. If you look at them main board you can see that they're popped.
And some blown capacitors can still work. They will just be noisier and won't work at 100%.
@@johnmacedo4483 I didn't see any of those in the video
سوىرىشبؤوي 😂انت عامل من نفسك عشان مش
@@user-dw9yv4bh2t i understand everything 😂
👍🏻👍🏻👏🏻👏🏻🇧🇷
I have a question，after the transformation, 12v becomes 8v, 5v becomes 1.5v, and 3.3v becomes 0v. what is the reason? The digital display shows 3.3v,5.2v,12.4v.
Se queda pegada la mano o algo así?
Всё хорошо! Только выключатель на передней панели стоит неправильно!!!
no final do vídeo você testa um carregador de pilhas... você que montou ele também? acabei de me inscrever e não sei se você já mostrou como fazer ele no seu canal... se possível poderia mostrar o esquema? obrigado
ua-cam.com/video/JkJNguFuPso/v-deo.html
Schematic was included in the video! Thanks
What do you call do the board shown at 3:15? I don't have that one in my ATX power supply. Hope you'll notice this query. Thanks
What I am wondering, is if the ATX PSU has a control module to regulate the voltages and if there's a way to splice a potmeter into there to actually regulate the output voltages ...
You can add a variable buck converter to any rail of this power supply and then you can control the voltage according to your preferences
👍👍👍🙂🤝
Uma bela gambiarra.
i did all the same but the amps shows 0. also can i forse the psu to give 10amps to work for a peltier?
The connection of the rotary switch in the diagram have my doubts...how do you just connect to the rotary switch and then direct connect to the output (banana plug) without going through the rotary switch...how is the rotary switch going to function? Or where am i missing something?
Nice power supply. But what's use of the voltmeter when all the voltages are fixed? Is this voltmeter only use to show changed voltage when you're connecting output cable to another terminal?
I've than it. tnks admin
Hi, I have a question, should the resistor be connected to the negative side of the diode from the usb?
Sorry, should be connected to the anode.
@@LahisTechLT thanks.
If you are using 40ohm dummy load resistor then 3w would have been fine
