    Picked up a quad today with no ram/hdd and only a video card on it. Had an aftermarket cable but at the sellers it wouldn't boot or power on at all. Took it home and tried with my main Quads cable and still nothing.


    - taking out pram battery held reset with it in plugged.

    - taking out gpu and then plugged it back it

    - added ram from other machine

    All didn't work. It smells musty so I think moisture got to it and killed the board.

    Anything I missed?

    If there's nothing at all, it might be the PSU that's bust..

    It might have leaked coolant, so inspect all the circuit boards in your PowerMac G5, and also look for any liquid stains. The PSU could have been leaked on too, since it's underneath everything, where logically coolant could flow down to.

    Checked there was no coolant leak. I am thinking its the power supply as it doesn't make a "click" noise when plugged in like my other quad

    Here is a few on eBay. One as low as $45 plus $15 shipping. Not terrible I guess.
