    @groenkek if the address is real then it doesnt work

    What could possibly go wrong?

    @groenkek CE can stand for two things, either Chinese excrement or Chinese export. Your choice.

    I have a 250 W from my old PC, was thinking to use it for powering electronics and stuff, as a bench power supply!

    @N0-Flux-Given give it a try, it's very easy.
    To jump start it place a clip to short out the green and any black wire in the main plug.
    Red is for 5v, yellow for 12v, orange for 3.3v and there is also negative voltage if you need that.
    I already have one 100w and now 400w. And they work perfectly.
    Also have a tool I made out of a hdd that must be powered by a power suply...

    Btw, If you don't know how to do it:

    https://instructables.com/id/...

    I checked this page for voltages and stuff.

    @groenkek You want to see inside to get really scared?

    @olback CE Is also the Europian certification for quality... Or something like that

    @GyroGearloose instructions unclear, got dick stuck in cooling fan. /s

    I'll make some cool 12V led strips powered by that PSU and controlled by aurdino.

    Well, don't follow that Instructions lol That's for Pros.
    What you need is the picture to see what are the components (to learn), The picture with the wires and their voltages and do it yourself.
    -I only used the main plug.
    -Left the rest of the wires cut but unstripped.
    -Left room for extras (USB plug , 9V exit for example)
    -You need to short (connect) the Green and one black (Or place a button in the middle), 1 Red + 1 Black for 5V, 1 Yellow and 1 Black for 12v, one Orange and 1 Black for 3.3V
    - Pick the terminals you want, I salvaged these ones from another board I picked in the scrapyard.
    -Buy USB terminals from Aliexpress and you can even charge your phone.
    -Don't forget to test all the terminals in the end with a multimeter or LEDs before testing anything.

    @N0-Flux-Given Do you want me to make a tutorial for complete noobs? Something even easier that what (at least I found) online? I don't mind because I'll just post it latter.

    @GyroGearloose No, I was just kidding. What you said is clear enough. :)

    @N0-Flux-Given Thanks :p Tought I might just do it when I do my third power supply.

    I guess cooling and flammability weren't design priorities?
  • 1
    @Fast-Nop Not really lol :p Should I make some holes in the box?
  • 1
    @GyroGearloose yeah I guess so. You could take the classix ATX design as example where you have an entry on the bottom of the front and an exit on the top of the back. That used to work even without fans because of air convection.

    @Fast-Nop Well, gonna check first if it heats up. It's just wires in the wooden box so it shouldn't heat much.

    @GyroGearloose wait what? I thought the voltage conversion was done in that box. :-)

    @Fast-Nop Nope...
    I'm using a computer Power Supply.
    400W
    Used the main plug to get my wires and saved the rest to run DIY tools from HDDs, CD-Roms and such...
    Later I'll add USB ports too.
    My first one only has 100W (better for saving power), Two USB ports as 5V and 4 nails (two pairs) for 12V

    Waiting to finish my First CNC so I can make this shit a lot prettier :D

    Btw this is my first 100W power supply and tool sharpener.

    @ScribeOfGoD @olback that was the joke. I extra checjed at the time of writing the fqdn to make sure it didn't exist
