    Hello folks,

    I'm trying to repair an old ATX compliant PSU for an old mobo. Apparantly there is no way I can think of to make it run with out hooking it up into my mobo. But I'm pretty sure there must be some tricky ways do so. You got any ideas ?

    Okey I'm almost done, the technics is known under the name of startjumping, and in order to switch it on, it consist of attaching any black wire (ground) with a green one.

    Well that's in case you encounter something similar,

    This is right,BUT only for testing the power supply.. I have changed out the fan on some of them,BUT other that IT is Always better to just replace it...Power supply's when they go bad can cause fire's,Or even Blow up.. I have seen this twice now..

    Well as you said, better wipe it out and get a new one, but now I got it work, changed one burnt fuse and 2 capacitors. Apparantly it's providing good voltages and ready to get its feet back in the case.

    Actually this technique isn't just used for testing. People use power supplies all the time to run amplifiers connected to car subwoofers.

    Coming from somebody who has literally had a PSU ignite in their lap, remove it immediately and buy a new one.

    Depending on what's broke, yeah, you probably can. If it's the PCB, that could be tricky. If it's just a component, a replacement can be done.

    However, be extremely careful when messing around in PSU. You can receive a nasty shock that could even be fatal from the capacitors inside. And yes, this is even when the PSU has been unplugged.

    Right. If you were to offer me $70 to repair a PSU that could potentially explode, then also run the risk of frying my other $700 worth of working PC components when I drop it back in, I'd have to politely decline. :)
