    Testing a PSU

    I've got a PC with a dead mainboard. Typically, when changing these I also change the PSU as I've experience has shown that with these (RM F-Series) PCs, the mainboard failure is as a result of a PSU failure. That said, I'm on an economy drive at the moment, so don't want to buy a new PSU if I don't have to. I would therefore like to test it to see if it works, but obviously don't want to plug it in to a different PC and risk blowing a second board. Can anyone suggest another way that I could test if the PSU is also dead?

    Get in the bath, turn it on - if you are still alive it's not working, if you are dead then it is.

    Yeah I have one, though it does not pick up underload faults, such as our new PCs are prone to. It will however give you a good idea if there is an obvious fault.

    If you just want to see if it powers up, stick a paper clip in the plug to link the green and black wires (several black - they're all the same)

    That works yes, I used to run a PSU like that to power some internal fans separately from the main power supply.

    Should probably mention that whilst performing the paper clip surgery make sure the PSU has been unplugged for a few minutes first - capacitors can still store a nasty kick for a while after powering down.

    That certinly sounds quite origional!
    Would it not be better to get a few power cable splitters for something as un energy consuming (no thats not correct grammer) and run the fans off that?
