I just watched your build and found it very interesting for my level of electronics.(LOW)!!! For my level and a lot of other people’s level this is a great job to learn how to work with the parts and such to put them together. I also read a lot of the comments and it seems a lot of people seem to forget about us uneducated learners. We need these jobs to learn from.
This is THE diy power supply, look no further. I used your fine adjustment pot solution for mine. I had a problem bc i didnt use the same dc dc converter so i had to use a boost one and a buck one, in top of that i needed -12v with at least 5 amp (for chip power amp test, like 3116d2) so i had to use 2 pc smps in series, but it turn out well, i used an old (really old) dual cassette deck as enclosure. Thank you very much for the tips.
A tip on soldering, tin the wire first and what you are soldering the wire to. It makes for a better and stronger solder joint. Also avoid what's called "cold joints" if there is not a shine on it when it cools then redo it. Poor joints can break easily.
If I have to pick on something, you should have shorted DATA+ and DATA- on the USB host connectors you want to be detected as "AC Charger" mode. Also I'm a bit uncomfortable on exposing GND as the VCC of the USB port you power from the -5V rail but that's probably just me. By the way, I think the quality of the video is great (I particularly liked how you edited the sound)
Thank you for the tip, I will investigate the short DATA+ and DATA-. If you are a bit uncomfortable on exposing GND as VCC, you can use the normal 5V (red wire) for usb as well. Thank you for watching!
@@creativesolutions-diy , the standard to refer to is Battery Charging v1.2 Specifications for USB 2.0. The core of the matter is that USB 2.0 made USB an interface which could also deliver power (more than 500mA) and deliver just power. In order to make it possible for devices to understand if the cable that had been plugged in could source more than the old 500mA and, at the same time, for the manufacturer of PSU to keep making reliable but cheap 5V units with only a change of connector the BC Spec standard defined having DATA+ and DATA- shorted as the solution. You can use an app like Ampere on a phone: when the phone detects a "dumb" charger the app says "AC Charger", when the phone detects an host which can communicate (but is not expected to deliver more than 500mA) then the app will say "USB Charger". My "discomfort" about grounds comes from these considerations: if you were to power two devices from these two USB ports and those two devices ended up being electrically connected in some way, then the "GND" in each of them would actually be 5V apart and the consequences would be bad. I admit it's unlikely but here is the designer of electronics thinking about what could go wrong rather than the tinkerer. Thank you for the video and keep up the good work.
Great work. But you didn't test current potentiometer I was expecting :( Can u tell your test results at 24-30V. Any issue? Like voltage drop and is it safe to use these usb's for charging smartphones? Thanks.
Others have made atx workbench power supply videos and you still came up with something new. Great job coming up with modifications and a really nice label in front. Well done! How many amps are you able to get out of the variable side?
Este video fue publicado hace 2 años pero espero que me puedan responder. Se puede hacer con cualquier fuente de alimentacion? Porque algunas varian con la cantidar de potencia que ofrecen...
The hardest part for me would be forming those holes on the front panel. Not everybody is equipped with the right tools to make and smooth out those holes.
Nice work, I think you would love a dye grinder, you could replace most the tools used here and save time. I love mine, wish I had an excuse to use it more.
Muito bom vídeo. Pena não dar para ver o valor da corrente máxima seleccionada. Mas suponho que começando com uma corrente baixa e depois ir aumentando não deve danificar o circuito?
Hi, I have a similar psu without green cable and a gray cable, can you please advise what you do with the gray cable, did you just cut it away? And what is the resistor type you are using? It would be nice if you can put the details on the video.
Hello, first congratulations and thank you for this great video.at 11:26, for the potentiometer 1 K you do not solder the wires in the same order as on the diagram, is there an error on the diagram? (video: orange, white, brown / diagram:brown, white, orange).
Great job. I have a question about the roket 3 pole led switch. Can you explain how it works? It is a led with polarity it seems doesent work in realtà but only in video
It is really an impressive work! thank you. I want to ask you about the custom label that you made for the outputs, can you upload it ? I want to print it and use it.
Well done, I have now done one of my two tasks thanks to this : 1) Find a good makestuff channel to subscribe to - Check! 2) Make an ATX lab power supply - will do soon!
The good: 1. enlist the components and their buying links 2. motivating viewer to build one. The bad:1. Fast forward of full time to build this, since you are too lazy to edit. If you edit unused steps you can run the video in normal speed and viewer can understand better the steps 2. No explanation on what are you doing on particular time 3. No knowledge sharing about which atx cable used and unused, the boost buck module and R shunt, etc 4. Background music represent low confidence level on the video quality while your video is actually good. See for a good example: DIY PERKS, no music, full explanation. 5. At least: SUBTITLE ON EACH STEPS would be appreciated.
Excellent Work!!! I have 2 question. ¿the dc-dc module can adjust the supplied current?? and the other question : that dc-dc module can supply (elevate) the voltage more than the 12v from the ATX??
@@creativesolutions-diyI see how confident and comfortable you are working your way around that ATX Power Supply .But I don't think many of us have those hand tools you have in your service. 1-) Converting the power supply into bench power supply is the seen part of an iceberg which you successfully demonstrate in this accelerated video in a fashionably manner It would have been time bound otherwise. 2-) Being able to acquire and use those hand tools comes with a territory.

Great video! I am gathering the parts to build my own. Question: I don't understand the purpose of the 10 ohm 10 watt resistor across the 5volt line. I have seen this in other designs. Thanks.
Computer PSU style supplies need some load to work properly, otherwise they sometimes wont start or output voltages fluctuate. So this resistor is that load.
Great video. What's your wiring for the LED rocker switch? Black for Ground, Green for + but what wire for the centre ACC post to make the LED light? Red?
Excellent Project. One of, in not THE, finest Power Supply builds i have seen. Is it possible to replace the 2K and 1K potentiometers with two 5k or two 1k linear potentiometers? Keep up the great work. Best regards
No it isn’t. You need to use the same potentiometers there are in the DC-DC converter that you will use. I only added a little 2K potentiometer in serie with 50K to allow the fine voltage adjustment. Thank you!
@@creativesolutions-diy: Hello again Rui. Do you have the the background image in an editable format so that i may change the color scheme? Like Coreldraw, for example? Thank very much. Cheers...
Everything is very good, but I have 2 questions, what is the 10w resistance 10 homnios for, I am not an expert in electronics, but does it seem almost a short circuit in the 5V line? And the usbs I understand that they need some resistors on the data pins so that the device (cell phone) takes 1A or 2A if they do not have those special voltages on the data legs it only takes 0.5A
You are right, if you will use the usb port to charge the cell phone you can short the -Data with +Data pins. The 10w 10ohm resistor is for dummy load because computer PSU style supplies need some load to work properly, otherwise they sometimes wont start or output voltages fluctuate.

Muy buena, y muy bien presentada pero q pasa si la carga entra en corto en la salida de 5v, o la de 3.3, o tal vez la de 12v, bien la fuente se protege pero y la carga se quema.
amazing work! congratulations, thanks for sharing. Do you have the link of the reuploaded project? because it seems to be down. Thanks! greetings from Argentina
Are there any potential problems with using multiple ports at the same time? e.g. supply an arduino on one of the lower fixed voltages and maybe cpu fan drawing .5-1A on fixed 12V and another load on the variable voltage and making sure all this adds up below the rated specs
In the past, some young kid died while he opened power supply. There are big capacitors which hold high voltage, those need to dicharge before you start play with your life.
nice video but just warning connecting USB ports like this (it will work) but some devices are making problems when charging. (learned it the hard way :) )
Any tips on converting a 50-100amp Single rail PSU for in-house/bench car audio testing? I need to be able to test car audio equipment with current pulls of up to 100amps (looking into 300amp PSUs as well) thinking I can use this same deal on a larger h it and just switch out what I want/don’t want.
Excelente, Rui. A maior dúvida que tenho, vc alimenta esta pequena placa (DC - DC Step...) com 12 Vcc e consegue até 30 Vcc na saída @ 3 A? Ela amplifica a voltagem?
Sim, o circuito mostrado é uma fonte de alimentação chaveada e tem a saída ajustável de 0 a 30V, desde que a tensão de entrada esteja dentro dessa faixa (de 0 a 30V).
The USB connected to the - 5V rail is a really bad idea. It gives you some more amps, but also a GND that is on -5V compared to the other GND in the same device. If you use more than one supply for a single device, you create a nice short and could burn through your cabling or even destroy the power supply
You are right, it's not a good idea, but usually the usb port it's not used to power a device together with another output. But yes, the best it's use the +5v instead of -5v
@@creativesolutions-diy have you ever seen the split power cables to power external hdd since one port would not allow enough power if it is compliant with the spec? Yeah I've got multiple of these for different applications

Can you tell me what was the original value of trimpot which one is removed from buck converter. I’m using Xl4015 buck module which has 103 trimpot for cv abd cc what should be the pot value according to your circuit.
By far the finest build I have come across regarding ATX power supply conversion to a general bench power supply. Very well done!
Thank you for your words!

Is this power supply within reasonable ripple output? Or would it benefit from further reduction of dc ripple.

OK, saw your resistor details is 10w and 10 ohms, can I use 2 x 5ohms resistors to add up to 10ohms?

what can be replaced with a 10w 10Ω resistor and a 2k potentiometer
thank you
