• Diagnose Whether a Mother board or PSU Has Failed - Shuttle Failure

    From Max Collisions@21:1/5 to All on Sat Dec 17 15:34:16 2022
    My Shuttle XPC has stopped working.

    So, what is the procedure to diagnose whether a fault is with the motherboard, or the PSU, when there are no beeps, no LED (Voltage Good) Signals, or lights, and nothing “happens”

    What I have done: Installed a known-good PSU for what I think is the dead one. (1)

    So, do you connect a working PSU into the machine, and check voltages of the ATX1, and ATX2 output ?

    Currently, I'm lucky, that when I moved the SSD hard drive, and Radeon GPU, into the less Powerful shuttle, with an FH61R motherboard, Windows 10 pro did not complain.

    (1) The ATX2 power socket on the XPC motherboard, has a 6X6 connector, the "spare "PSU"'s have an ATX2 connector that has only 4 connectors, which fits snuggly only one way on the Motherboard’s ATX2 port, some are round, nd some are round + square.

    Thanks.

    Do any of the capacitors in the PSU look swollen?

    All Capacitors look in fine condition.

    I have shorted pins 4 and 5 of the Shuttle PSU, and the power supplys fan runs, and there are +5v + 5V, and +12v + 12v's showing on all power connection from the PSU, so it looks like a dead Motherboard :O(

    Not necessarily, you need to test the -5VSB rail as well on the PSU
