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.
You did a great job!
But didn't I see a + 12 volt & -12 volt? You could have added a 24-volt option!
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....
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.
great video thnks
Awesome job, did u publish a parts list? With numbers?
Very good video ...except music was TOO LOUD!
A superb job.well done sir.
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 ???
Nice presentation......
Thank you
Hi Friend nice video but what is the point of the selector it wont show the real voltage you still need to select the correct voltage you need from the red plugs.
CAUTION:
It should be clearly stated that the knob does not change the voltage on any of the outputs... it only changes which voltage rail that is being monitored by the voltmeter portion of the display. If you turn the knob but do not change the wires from one set of posts to the other, you might fry your project by mistake. If you build this project, it is important to remember this warning.
Robert Cartier yeah 100% true. thanks.
He should have a volt meter for each rail or may be have the knob switch between the different rails while the display put parallel to the knob so that it changes with the power supplied
DAN OKODE only thing you have be careful of , from which rail you gets power according to your application. 3.3v , 5v or 12v...
i expected it im like how did he do that , turns out he didnt hes just making it look like that , i made the real thing its here drive.google.com/drive/u/0/folders/1WiVQ2QsuwcQILfkM251yoagN3w08bVVy
@@dedskin1 If you have the knob switch the actual voltages to the posts as well, why do u have 2 sets of posts? P.S. Not tryina be judgemental. Genuinely curious.
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 👍🏼
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
Good
Can you tell me the motor specifications or from where I can find it
the highest rated binding posts I can find are 16A. ... don't you need one that can handle 30A?
Oi amigo precisava de uma dessa sera que daria pra fazer uma dessa pra mim quanto cobraria. Para mim seria muito bom
Very good
good
Tengo una duda, al parecer mi fuente atx no tiene fusible pero le quiero agregar uno solo que no se donde ponerlo, ¿será correcto si lo conecto en serie con mi switch de encendido del stand by o donde deberia colocarlo? Si alguien me puede responder le agradecería.
instead of 10W 40 ohms / 10W 20 ohms x2, can I use 10W 100 ohms?
Can you please tell us why this dummy load is required?
How do you discharge? Sorry im a beginner
I did not understand everything. You made separate 3.3v, 5v and 12v outputs. Then what is this rotary switch for?
Tomasz Es to switch the outputs for the Amp/Voltmeter.
Ok. Thanks. :)

not quite good. I suggest, since you have a selector switch then rewire the connections such that there should be an output terminal consisting of one positive and one negative terminal which will correspond to the selector position and the voltmeter. if 3.3v is shown in the voltmeter then the terminal voltage output should also be 3.3v. If selector is switched to 5v and 5v is also shown in the voltmeter then the terminal voltage output should also be also 5v and if selector is switched to 12v and 12v is also shown in the voltmeter then the terminal voltage output should also be 12v.
Hot glue for 2x 10W Resistors?? LOL

Sorry it should be gray (the wire which indicate the power is ok in psu via lighting up green led in psu through 330ohm resistor)
Don't copy others'. Use your own ideas and make
I have Question how Much ampere can bear this supply
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.
Yes you must connect in series with and before your on off switch. As fuses are rated in amps so they will be connected in series.
Таке запитання, у мене є 1 блок питания з шим контролером EST7502B вийде зробити лабораторний блок живлення з регулюванням напруги?
i don't get it when selector just display the voltage but all the pole was independent voltage from 3.3v, 5v & 12v.. don't be mad but for me it'd useless selector & lcd display.. unless just 1 pair pole but selector make the pole have the voltage like appears in lcd display..

I have seen many videos of ATX power supplies turned into compact bench power supplies mainly for using with CB radios. Still i think its a hazardous project to turn an ATX power supplies into a bench power supply. But none of the power supplies can get over 12 volts. So to use a cb radio at 12 volts will work but not fully. I rather get myself a real power supply that gives out 13.8V DC for my CRT SS9900 Amateur radio to work correctly. Its a neat project but dangerous. You really should know what you are doing!
Good Job. Identical project to "Sorin - DIY Electrical Nerd".
It's a copy from sorin
No se explican las dos pcb que hay una pequeña montada sobre un disipador,
Y la que soldas las patas de 220v de entrada.
No se explica para que son y como se conectan, y si las hiciste tu ambos pcb.
SERGIO
why did your ATX not have a mains plug ( power connector ) already fitted.
my Atx I am going to use already has a mains plug ( power connector ) in situedo I have to modify it in any way
this guy dont know what is heat. 16:06
this looks like it was directly copied from sorin-the diy channel. not cool man not cool. the atx even have the same exact layout and functions. even the damn thumbnail
Buena aportación, pero si comentásemos más el video mejor. Gracias. Good contribution, but if we discussed the video better. Thank you
This man always copy from other
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

What about the short protection ? Is it disabled ?? Otherwise we won't be able to run at high amp
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
Very nice
Alguien me dise si es peligroso tocar 5v a 40 amperios si no me cuido a tierra ? Porfa
What is the use of the two resistors with the red and black terminals that you connected?
What the hell is the point of the rotary switch? You can still access 5V when the switch is set to 12V on the display? I kean yeah you can see what the voltage is, but this power supply is just asking for to plug a 5V circuit into the 12V socket because the display says 5V. At least cut the power to the other sockets when you're not using the respective voltages.
Sorin explaned why the rotaty switch!! it is more to use the Amp feature of the voltmeter!! to know the consumprion of each device when testing......

Kenapa ditambah dengan resitor untuk +5vnya
Essa ligação do botão está errada pois ela só vai medir a tenção interna da fonte e não o valor da saída de B1, B2 e B3.

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
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?
I have a psu that worked, connected green to black and it turned on the fan. After cutting the wires, when I connect green to black, it spins the fan for half on sec and then it stops. And idea? The purple 5v has power for an led, but the other wires stop after half second
That is not a lab pwr supply; you cannot set the amperes,and you ONLY have 3 voltages;
I use that sometimes, with no box, for the 3.3 V,which i convert to 1 volt with 3 power (17 watt) resistors (forming a divider) ,to inject voltage on laptop motherboards to find the short circuited component. Other times, other circuits, i use the 3.3 or the 5 directly.

Для чего тут 2 резистора соединённых последовательно?
Buy a heat-gun! I see so many videos using a match or a lighter to shrink heat-shrink tubing. It kills me! Go to WalMart, Target, Home Depot, wherever, and spend $10 on a heat gun!
He needs a jigsaw before he needs a heat gun but I agree that he does need one.
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?
Why use of dummy load with 5 volt plz enlight me
can you explain why you use dummy load?
Good repurposing of the SMPS / ATx power supply
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?
I don't know much about electronics but I am struck by why connect the two 10-watt resistors to the 5-volt output, why that connection? Anybody could tell me please?
Brother you can reduce the cost.. just remove the volt meter and rotary switch... No fun of using them coz it's fix output .. if it's variable power supply only then it needs to be there... Just put marking 3.3, 5 and 12.. as I did in making my own 8 years ago
Apna skill gun ga ban Kar rahe ho.ache se explain Karo.
im the 6666 like! :D incredible video! thanks man (from Argentina!)
TALK TO US! Explain what's going on. What you bought, where you bought it from, type numbers, hints & tips etc,. etc. It's not difficult to communicate surely?? Stupid background music and ambient sound is no good at all!
I hate having to work out from almost silent videos how to make stuff that would otherwise be interesting and useful. This is the second RUclips video I've tried tonight about making a bench PSU from a computer unit that turned out to be a waste of time . Gave up on them both.
Now i get what you trying to do with between the meter and the output is independent of one another ...ok ok
3rd music video in 5 minutes ! STOP !
Hot gluing power resistors? Prolly a bad idea.
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?

@LahisTech
WTF/1
This is not the bench psu! It's just SMPS with bannana plugs and amp/volt meter! Bullshit...
Nice design. Lousy video!! No verbal explanation. Very strange. That's what you get for free lol.
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%.

Please tell me why connect risitter 40ohm?
Why don't these people learn how to solder properly?
The cost of converting one of these supplies didn't make sense to me, especially if you don't have one lying about.
By the time you factor in parts and labour you may as well by a ready made cheap unit from Amazon and you have a warranty.
👍👍👍🙂🤝
:) Where is current control? You can use internal opamps of TL494 for CC and CV.
Actually, you didn't soldered the purple wire in USB port which us impossible that USB works without turning the power supply's on.
In your diagram, Connecting the RED wire of Amp-meter to GND to will not read a NEGATIVE VALUE ??? I mean the amp-meter will not be damage ?
that 16 item cost lot, not worth this to make.
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!!!
The potensiometer did'n t work to be change the voltage of output current, but change only the voltmeter indicator,because missing the output wiring from potensiometer to an ipotetic variable output connector
Muito bom, só falta o áudio com explicações profundas.
If you are using 40ohm dummy load resistor then 3w would have been fine
Hola amigo donde conseguir los elementos y sus precios
Cuales son sus desvntjas
i did all the same but the amps shows 0. also can i forse the psu to give 10amps to work for a peltier?
please ignore my comment sorry not related
Brod... it is possible to use only one black binding post since it has already a selector?...
👀Looks up variable power supply ooh BANGOOD AU$27.00👀
IF I bought the parts separate about $50 ? haa anyway good tech build🤷♂️
Mark Arnott as always 😂
I have a consult. What is the voltage output of USB port. 5V 1AMP or which?
