  • For what the hell is the on-off switch between GND and +3.3 V? To turn off the "GND" connection? I think it is superfluous. Computer power supplies have protection against overtemperature, overload and short circuit.

  • @djblackarrow That is to power the PSU up. The big switch is controlling the Line voltage but the smaller switch is connected to Pwr on (green wire) and Ground

    :)

  • Nice one! :)

  • @JumperOneTV Thank you :) Great tutorial btw :)

  • @bjarni1995: Whoa - That's right! I'm just not thinking of the certain green wire. I'll bite me in the ass.
