    For Powermacs G5 you can try to boot with only one cpu at time.

    In your maintenance disassembly/reassembly you can have damaged something like cpu socket/cpu board.
    Be sure your cpu is in full contact with its heatsink.

    I have rebuilded from scratch G5 quad LCS with custom parts, I know manage powermac parts is not a joke, it's completely different beast, not sure an usual pc.

    Try also to reset pmu and spu and change cr2032 battery.
