Ciao.per favore quello che non ho capito .il filo rosso e nero che tu porti alla resistenza esterna .e per caso un positivo e un negativo se si perché quale la sua funzione.gradirei una risposta.grazie.
😊
I believe that this man is the best general-purpose maker man on youtube. Drink-dispensers, air-hockey tables, small benchtop tools, now a power supply. Bravo!
🤣🤣 thanks
I've been saving this power supply for years hoping to do something like this. I hope mine will look half as good as yours. Great project, thanks.
For all of you asking "WTH is that resistor on the 5V doing there?": For the PSU to correctly regulate the +5V output voltage it needs to have some sort of load attached, at least 5W to trick the PSU into thinking its attached to the motherboard.
If I were to do this project, I'd likely try using a 5W LED light, on a flexible stalk.
@@JamesGravesJr Great idea! Often when we are working we need a task light to focus on some thing we are doing.
Some power supplies don't need any resistors on the outputs. I used to buy and sell computers so I have quite a few spare PSU's and some of them seem to work just fine by shorting the green sense wire to ground to get it to turn on, as other PSU's will need a load on the output to turn on.
Nice!
@@mashedpotatoes5323 i think that most of them have a cooling-fan with give that load
Wow that one sure is nicer then the one I made a few years back.
my thoughts exactly.
Perfeito, O melhor projeto com fonte ATX que eu já vi aqui no KZhead. Parabéns. Excelente vídeo.
So most supplies you find on the tubes use 3v, 5v and 12v wires, each with it's own terminals. This uses only the 12v for usage and uses the step up step down to adjust to what you want, which also adjust the current (amps). I like it.
I love the idea of finger-testing feature located to the side of that box. Just put the finger into the hole on the side and gently move around to detect if 230V is still present :D
Always that one guy neh lol
I"ve been saving one for just this purpose but didn't stop to figure the cosmetics of it all. Thank you for laying all out like this!
Laying it all out how? He explained nothing. Do NOT make this without further research or you will seriously hurt yourself! Super irresponsible of Daniele Tartaglia to post this crappy video.
Thanks, I like the variable addition. FYI, rather than an expensive 10 ohm power resistor, I use an old 12v 1157 taillight. The 5V lights up the inside of the box with a glow to tell you it's ON.
Is the 5v from the power supply going to high or low beam on the bulb?
What is the function of the power resistor? can it be replaced or is that expensive resistor optional?
@@diegof.8052 Some power supplies do not turn on unless there is a load on it. Basically the resistor makes the power supply think its connected to a motherboard so it can supply power.
@@miguelcalderon3702 Thanks for the clarification. The power resistor used in the video is expensive, do you think the resistor you see here amzn.to/3lw9rGO can work? By the way, to date Daniele Tartaglia has not yet uploaded the schematic electric or the list of materials he used. 😒
@@diegof.8052 well every power supply is different so one might need a 10 watt resistor, others 12 watt and so on. But yes those resistors should work just fine just make sure you have some kind of cooling in the housing like a fan or something to keep the resistor and components cool. And to turn the supply on just need to ground the green wire(you can can connect a switch between both wires so it only cuts on when you press the switch. And for a 12v power supply connect a 3-4 black wires to a black banana plug(-), and 3-4 yellow wires(+) to another plug and you should get 12 volts and the same thing applies for the rest of the colors on the supply. Just make sure you know the output power of the wire colors on the power supply. And careful when testing inside the power supply because they can produce alot of amps and that can really mess you up.
I suck at soldering, so I usually take the easy things from my old power supplies but after watching more of these videos. I think I'm going to work on my soldering techniques and start scavenging the "harder" things.
THank you for the content. Some suggestions for you: I'm unsure who you're target audience is, if you're aiming to capture novice electronic hobbyist I suggest you clearly identify all the wiring junctions as you go through and solder or terminate. Thank you again for your time. Cheers from Australia
Very nice! Especially the artwork makes it look way better than just a regular psu. Makes me want to build one too 👌🏻
sweet!!! should have put a dedicated 12V in there too right off the ATX Board
The Exterior Load Resister Is 12V, It Could Have Been Inside the case with a front panel 12V Connection?.
@@georgeveghte6459 He used a red wire for the resistor, that is 5V, not 12. But I agree that the resistor should have been mounted on the inside.
Need of that resistor???
@@alpha2.017 The Load resistor? Yes. Not only does it let you power up some older PSU's, it should be used anyway, even if not required to keep things running... Because it also regulates all three voltages. The readings will be closer to desired voltages and remain as stable as possible.
@@robertcartier5088 can we use LED as a load instead of that resistor? 🤨
The graphic label on the front was an awsome touch I haven't seen before.
What was that wet applied film he placed on the front over the printed parts?
@@WarrenPostma You should be able to find them on eBay, Amazon, local hobby and craft stores etc as Self Adhesive Craft Vinyl (or simply Sticky Back Plastic). You'll want the clear stuff of course.
I made a less refined one of these years ago. It did it’s job and served it purpose until I pushed it beyond its capabilities. This video has inspired me to make a new one. I have a lightly used 1400w modular Corsair PSU sitting in my graveyard. I think it’s time to see what I can do with it.
casually fabricating a regulator from a 650$ psu? noice.
can you please give some information of potentiometer it will helpful.
same value as replaced part. many kit has different value.
I zoom into the component.. seem to be a 20 K ... i'm waiting for the part, and will order multi-trip pot once received :)
@@erikgaudin W 204 (BAOTER 3296) is a 200k trim potentiometer
@@AttilaNagy777 Do you think all potentiometers are 200k?
turn left --- resistance goes up turn right -- resistance goes down Now make a headstand: All the other way around .... *magix* Or look at the website from piher (a potentiometer manufacturer for THE manual) ... :)
Looks amazing! What materials did you use for the decals? I’ve never seen that process before.
AN EXCELLANT RE-USE OF AN OLD AT POWER SUPPLY. VERY NICE WORK AND DETAIL. THANK YOU!
I'm certain I saw some leaking electrolytics in the ATX power supply. Good idea. I was thinking of rewinding the transformer and feedback on one for a single output, variable voltage (9 to 15 volts) power supply. Much easier to leave the other voltages intact and add an adjustable boost/buck converter to the 12 volt rail. I'd also add a few extra grounds.
Hi my smart friend. Please can you define the Potentiometers wire diagram in details??? How and where are these connected. Thank you for your work!
Reading the subtitles is difficult. Instead of music you may read them. Load resistor could be inside. Very good project.
That's what you have pause for! Just press space to read the details or press left arrow to go back in case you missed it. I agree its a really good project, i saved two semi-busted PSUs for this exact purpose.
But then you would complain about Daniele's heavy accent.
This video would be so much greater with vocal explanations and also some safety instructions. Like no mentioning of the capacitors in there that may be shocking you if you are not careful/properly discharging them.
how the load resistor is connected?
@@negrit00 this is a small load required for proper functioning of the switch mode power supply otherwise with no load the pulse width will be nearly zero affecting other supplies. Here it is connected across 5v output. It is given in the subtle, but you missed it. This was the reason I had requested that subtles should be read as well. One expert has opposed my suggestion, see above.
cool! plugs, switches, knobs, looks manufactured! just like downtown. Love your garage band practicing endlessly.
I always keep my old ATX supplies. Although a tad noisy, by that I mean on an o scope, compared to a bench power supply, for hobby stuff, it is a great source of 12v, 5v, and 3.3v if you roll that way.
You regulate the Output with the step Up step down converter, this is designed for 8 Amps your labeling at the front says 10 Amps that couldn' t be correct!
Input voltage: DC5-30V Input current: 8A (MAX) peak 10A (6A work a long time) Quiescent current: 4mA (operating voltage is not the same there will be errors) Output voltage: 1.25-30V continuously adjustable Output Current: 10A (MAX) (5A long natural heat inside) Output current range: 0.2-10A
The link to the project in the description still just says it will be uploaded in a few days. Months later I’m still waiting
Best convertion I've ever seen so far.

The Good: The front panel artwork is awesome. I especially like the method used as I'd not seen that before. The Bad: As usual with these DIY supplies, there is no way to adjust Constant Current which means that the supply will feed its maximum current at whatever voltage it is set for into the load whenever a short circuit is encountered. Since these ATX supplies can deliver 25 amps or more, that can be very dangerous, both to the operator and to the circuit under test. It's a very useful troubleshooting technique to be able to dial down the current so that when power is applied, the current is limited to a level that is safe for the circuit. This is also especially useful for charging Li-ion batteries as you want to both limit the current and taper it off as the battery reaches its maximum voltage, otherwise it could blow up in a spectacular fireball. Don't ask me how I know this. Also, why mount the power resistor on the outside? It'll just bang into things and possibly scratch them up.
How would you incorporate "dial down the current" in this build? Thanks
That is intense, a lot of work n knowledge.
Na u can slap the shit together it should work
No.. it's not really that intense if you understand how a SMPS works and what these things do to begin with. all in all it's relatively simple but.. like he said BE FUCKING CAREFUL NOT TO KILL YOURSELF IN THE PROCESS OF MAKING IT. but all in all, it's not that intense
@@martinkuliza you don't even gotta know how it works to build it, just follow the video and don't touch the capacitors even if it's unplugged
@@martinkuliza i mean... just... discharge the capacitors when u get started?
@@DopeFox Yeah......NO QUITE in my day , you would have been called an idiot (you know why ?) it's because you're undertaking an electronics task (or any task for that matter) and you're saying, more or less.. "I'm going to do this but i don't need to know anything about it " That's just fucking stupid mate in my day , back in the 70s if you made a decision to do something you sat down and at some point you said to someone , ok TEACH ME WHAT I NEED TO KNOW BEFORE WE START You didn't say let's do it and i don't need to know or want to know everything that also defeats the entire point of getting into electronics which then gives rise to the following logical question........

Bellissimo. Complimenti. Come upgrade suggerirei una presa usb (se posso permettermi). Grande!!!!!
👍 my heart with italy and the world in these tough events ❤
Watching this video gets me in a tranquility flow.
One concern is the segregation of the low voltage circuits and components from the mains voltage. Usually build any extras externally or place within the low voltage side of the ATX case to overcome this point.
How is the voltage control and wiring method is the same when connecting other bolt meter than boltmeter shown in the video?
It surely depends on what "voltmeter" you want to use. The one he used had a diagram on its sticker for the connections. The control method he used was simply replacing the trimpots of the converter for regular potentiometers and sticking the knobs through the ATX PSU's metal cover for easy access.
Man, boltmeters exist? I’ve got all these left over screws and bolts and I’m not sure what will go with what. Had I know I could just get a boltmeter, I’d have just done that ages ago!
Best DIY bench power supply from ATX supply on youtube!!! Great job my guy!
U speed up the video were sorting out the wires can u explain pls
For the first time I saw such a great and clean work! Perfect 👌! You are a "Meister"!
Muy bueno Daniele! Es muy útil para el taller en cualquier lado. Gracias x compartir los detalles. Saludos desde Argentina
I would have mounted the dummy load inside on the "front cover" part near the fan for increased cooling and is out of sight. Other than that it's pretty good. Also some rubber pads (from old laptops) would keep the PSU from sliding on the table.
I would have first tested if my PSU *needs* a dummy load to start with. Mine for example doesn't. (Or the status LED is enough of a dummy load)
I'm going to make one, great job. How did you make the label? Can you make a printable download so I can make one?
My goodness, that was an amazing project, i'm impressed
Wow, this is brilliant and an art form
Hi, nice work ! I'm very interested in this project and plan to make the same thing with an old power supply of mine. I'm just wondering about the purpose of the power resistor of 10ohm added in parallel of the 5V output. Could you please explain its role ? Thanks in advance !
Most ATX powersupply require a "minimum load" to function/start up properly. My guess is that the resistor is put in there to serv as a "minimum load.
Thought there would be a dedicated USB plug from the early on-screen comments
This is an amazing design and has given me so many ideas, Thank you so much
Witam i pozdrawiam Daniele!!Wykonanie zasilacza to majstersztyk, duża wiedza z elektroniki,będzie użytecznym narzędziem pomiarowym,tak trzymać.Prima Daniele!!!!
A buck converter only lowers voltage. Perhaps he meant a BOOST converter, since he was getting more than twice the ATX output voltage? Or a buck/boost converter, which does both?
I'm pretty sure that part is a buck converter, you can find it a-plenty on aliexpress / banggood etc. I'm guessing he's hooking the - of this buck to the PSU -12V rail and + to the +12V. Not sure if that's advisable...
would prefer dialogue to music. good idea though.
Yes!! Great idea. Congratulations!!
THANK YOU!!!!!! Another channel I watch, the guys uses a lighter to shrink the covers but that's not what annoys me. What annoys me is he doesn't shrink it down as much as he can. The loose gap he leaves drives me crazy :). Also I do think he should use a more directed heat source like the one you used.
Good project! Just a perception: before you start the work with the ATX PSU, you should have replaced the electrolitic capacitors in it. As I see on the video, one of them (at least) already humped, it means it"s dead, maybe it will explode.
Ciao Daniele, complimenti. Sei un laboratorio di idee. Puoi linkare dove acquisti i fogli di plastica per fare stampe con serigrafia pannelli? Grazie
Encontrei o projeto perfeito para a minha bancada!!!
WOW I love it! This PSU is by far one of the best looking DIY power spupplies I've seen so far... One day when I'll make my own PSU, I'll make it like you... Nice work.. :D
You know...you could use the audio track to ADD INFORMATION to what you are doing.
Forget the power supply, I already have one. I'm much more interested in the bank of blinking LED's. Is that a kit or a project? Is there a source for it??? Ooooo... pretty flashing lights!
It's from hypnocube.com Here's one I made: kzhead.info/sun/mq1yYcp5fpFmlIU/bejne.html
17:24 Brilliant way to remove components! Thank You
that soundtrack though.. BOMBING!! play it
Very cool. Wish you would have hid that one resistor inside though.plenty of room to do that.
that screwdriver was awesome, but damn it was expensive.
I'm Indonesian and i really didn't understand their languange (maybe Spain/ Portuguese/ Mexico, etc or all latino languanges) but i amaze with this video of his manufacture skill. Although this video have no voice and there's no detail explanation but the project is very simple and easy to understand. THUMBS UP
Muhun kang, sae pisan... 👍
Hermoso a la vista. Ya que hiciste salidas de 3,3; 5 voltios, sugeriría hacerle tambien una salida para 12voltios, ya que la fuente los trae y no cuesta nada poner un cablecito más. Hay llaves selectoras de 6 contactos bipolares que se usaban antes muchísimo en radios, divisores para usar varias impresoras o monitores, que nos ahorraría orificios de salida y así tener en cada posición de la llave los voltajes respectivos con solo una salida y el GND. Un abrazo
Great job!! Very nice, clean and accurate! Congratulation! Please, can you show as the semi-transparent paper that you added over the printed background? A link will be appreciated. Just to know what to look for / order. Thank you!
You can use laminating clear sheet. I tried that in other project that require a panel. And it looks good.
Bravo! Molto bello e utile .Forse con un display retroilluminato sarebbe stato meglio ma capisco che non si può avere tutto.

Really nice job on this Power Unit!
Excelente, te quedó muy profesional 👍
waited for you to replace the swollen capacitor,But you did not notice him
Noticed that from your comment, nice observation mate. He will change them when they will probably wear out completely or when he sees your comment.
I was bored one day so I decided to clean out my psu and I almost died, do not stick your fingers inside one of these things if you don't know what your doing.
How long were you deaf for? Try shorting-out a flashgun capacitor that is really loud!
You have to make sure the capacitors are unloaded, simply remove plug from psu and try to turn on your computer.
@@SpyrosLv I guess I would have been fine then since I did that.
One way you can discharge the caps without attaching stuff to them (which could cause those large value caps to blow up if you exceed what they can take) is unplugging the supply off the outlet and keeping the power switch pressed for about a minute.
I think I would discharge them safely using resistors to be on the safe side. My first thought when he opened the box was, yikes! That is going to burn some hands. Never assume they are discharged just because they have been standing on some shelf for years. I once had a look into a DVD player that was struck by lightning to see if I was bothered to try to fix it. My thumb came across one of the capacitors, and in a second I got an entry and exit burn on my thumb. That for a device that had been unplugged on a shelf for a full year. Be careful, and know what you are doing before opening up. Those things are so easy to overlook, and you get no warning signs at all.
Very beautiful build. Love your attention to details.
No need for words, if you know your stuff you can duplicate and even improve it and I have like 50 of those in storage, good job!
Cool Build with a nice finish! :-)
1:37 13:06 In the secondary, there are at least two dead capacitors... one next to the white cables and another next to the heat sink.
how can you tell??
@@kwissiekwissie U see little swollen top
Also noticed... But certainly was changed.

The man is question is great. Never tell what he does, never give schematics, never reply the comments and what he does, he does for himself. GREAT MAN
New here, liked the final, but only one thing bothered me, that drilling into the voltage stepper. For some PCB's, multiple layers are passing through the surface but also inside the PCB, and that drilling can result into a short between them and here as i can see, was not the case.For someone who does not know what type of PCB is he working with that drilling might turn it into a 'camp fire', and i think you should at least warn about where and if they can drill a hole. Also, drilling the heatsink... understand that you've cleaned the remained chips, but you can never know for sure where they can get stuck, after all that power supply is working with deadly voltages. My point was to dismantle it, drill, remount. Overall I've watched this because i also wanted to do it, but....never had the time and patience. EDIT: My comment looks like hate, from a passionate to passionate, we understand how things work, but someone who does not, you need to explain them even the simplest things, otherwise they get hurt. I work also dangerous, don't care what can happen to me, but to someone else, always matters.
Also, that heatsink is going to get hot - possibly very hot - which could cause the module screwed to it to overheat and malfunction. And there's a good chance that heatsink is live too! This is a great little project, but the internal layout needs a bit of a rethink. Could be very dangerous as it is now.
@@ensor2872 Good point,noticed now also the fact that is a conductive material, which usually is not recommended to mount an electronic board on. Finally ,if he reads the comments he might do it 'better' in terms of safety factors next time, if not, well.
Could you give me the references of the 3 potentiometers used and in what order, thank you.
i need same info
I'd also like to now this
And me as well, thanks!

I was like, wouldn't it be awesome if this was one of those video's where after watching for 15 minutes the entire thing blows up in smoke. :P
This is a great innovation, knowledge
Hello, do you not replace the three inflated capacitors on the source before making the measurements for voltage and amperage?
nice and clean build. bravo ! just one question: why did you put the 10 ohms resistor out of the box ? there are still some room inside.
He did it for heat dissipation. That resistor gets hot
you forgot to replaced the bulging capacitors lol
I only came to the comments to see if anyone else noticed that.
The screw driver is awesome!
Good work To protect the ATX again short circuit. It will be better to connect the Green wire (power on) to Relay contact with black wire. And to energize the relay with the 12 v or 5 v accorditly.
Bellissimo lavoro sempre professionale ma non ho ben capito a cosa servano i potenziometri " A.limit " e " V. fine " ad impostare dei valori limite ? Grazie.
V.Fine Serve per regolare la tensione su scala dei millivolt perchè. Un giro completo corrisponde piu o meno ad 1 volt mentre A limit serve per limitare la corrente anche se non è possibile visualizzare il valore. Lo dovrai gestire partendo da un valore molto basso, con carico connesso, per poi arrivare alla corrente desiderata.
@@DanieleTartaglia si può realizzare lo stesso progetto senza A. Limit? La resistenza che hai messo esterna cosa serve? È il carico connesso?
6:09 - you have two bad capacitors there, and the rest of them are in marginal condition,they had to be replaced...
Esactly 😁
Daniele sembra anche a me di vedere un paio di condensatori gonfi :)
@@luigi_com Si, ma era un' alimentatore vecchio e non mi sono preoccupato piu di tanto. Comunque non sono gonfi da scoppiare, lo sono leggermente :-)
@@DanieleTartaglia vero, roba di recupero, giusta per il fai da te :)

I like the general idea, love your creativity - how many of those power supply boxes have I needlessly junked over the years?! Looks a bit complicated for my limited electrical simple however. Voice explanations (in English) would have been helpful though.
Your video is a masterpiece. Perfection ifself. Thanks.
Non ho capito perché hai messo la resistenza da 10 ohm sui 5v, posso chiederti perché l'hai messa?
Convengo. E perché la resistenza è montata esternamente? Altra domanda: il misuratore di carico è esclusivamente sullo step down. Tutte le altre uscite non sono monitorate.
Ci credo che passa tempo tra un video e l'altro: le riprese e la postproduzione portan via tempo e visto il risultato finale direi a ragion veduta! Il progetto in se è un eccellente upgrade di quello che facesti anni or sono ma il montaggio video, l'inserzione degli strumenti che pubblicizzasti e dei tuoi progetti a supporto/sfondo, denotano un ulteriore salto di qualità. Sei riuscito a superarti ancora una volta: i miei più sentiti complimenti! Saluti V.
Mi fa molto piacere che hai notato quei dettagli che credo facciano la differenza ma soprattutto, l' impegno e il tempo che ti portano via. Per riprendere una lavorazione che normalmente potrebbe impiegare qualche secondo e con molta facilità di lavoro, io ci metto dieci volte tanto con treppiedi davanti, spostamento continuo della camera, dei faretti, regolazione manuale della messa a fuoco, esposizione, diframma ecc ma soprattutto, i posizioni assurde che portano anche il mal di schiena. Non sono molti i commenti come il tuo e quindi, anche se perdo qualche minuto a rispondere, mi fa solo che piacere :-) grazie infinite
@@DanieleTartaglia ok grazie ha me piace molto se trovasse un po' di tempo...mi contatti perché lo voglio ok
@@giuseppefuoglio345 io te lo posso anche fare, ma ti chiedo a cosa ti serve?
Покажите пожалуйста схему
@@DanieleTartaglia mi piace tantissimo è vorrei alimentare un cb... baracchino ho un autoradio con amplificatore
Bravo,my friend good job ,all of your effort and knowledge paid off ,damn good build.
All have enjoyed the music. Thanks Mr. Daniele Tartaglia
4:00 Hey, that power supply has two swollen capacitors hahaha...
So Glad I wasn't the only one to notice ... obvious as soon as he took the top off @ 1:36 ... !!!
@@frankmc4294 i saw it even on the blurry video the second he took the psu apart.. how he didnt? or didnt care..
yep...thts ri8 but most buck modules are designed to taKE unsteady dc voltage input so that maynot be a prob
I saw it right away too and this makes the supply a bad candidate for this project as it is in for a eminent death if it´s not recapped. probably gonna make the voltage very unstable as the capacitors likely don´t have any juice left as well
Is DC-DC Step Down from 12V making 24V? Nobody mixed up anything?
Wait how did he actually do it? The power supply label has really only 12V max (0:53s) and the DC DC converter is really step down... that doesnt make seance. O.o
Oh wait that DC DC converter is step up and step down right? :D I think... 2:30s
It is a Buck Converter, within a certain range it is able to increase the input voltage.
After watching this, I bought almost the same dc-dc step down from local online stores. And then I realized this thing right after I transferred the money😅
@@febbyeka Yea classic :)
Nice build. Make me think of how much stuff we trow in the carbage that could have a second life.
I like videos without talk sometimes. This one is great. I love the music too. Sometimes you can learn a TON by just watching. Wish I knew what the music/group he has playing...
