    can anyone direct me where to troubleshoot a dead atx psu. a green wire

    was already shorted to ground (black) but nothing happens.

    i read from the net that almost all concepts of AT and ATX psu are
    the same.

    The differences are: that ATX PSU always has +5V standby (what color of

    a wire is the sb?), it powers up through logic circuit (maybe through
    ic w/c is in the psu itself) and that it can be controlled by software.

    i already have repaired AT psu many times but i do not try ATX yet.

    thanks in advance,
