Hello 68kMLA!
I recently acquired a G5 Dual Core 2.3, and it seems like the power supply in it is dead. It clicks twice when plugged in, and the "trickle power" LED indicator on the logic board only briefly lights up before going dark.
Somehow, I managed to get the Power Supply out of the mac, and thought that I might be able to repair it, or replace it with an ATX power supply - however, the last generation of PMG5s seem to use a power supply that's different from other G5s, as the connectors are completely different (and the PSU has bus bars on the top), so most online resources (like the Damn Technology mod, and every single pinout chart online) seem to be tailored to a different model of PSU. Picture attached:
Opening it up, I spotted what looks like a scorch mark on the other side. Not good! Most of the fuses read good though, and the PSU shocked me as I tried to turn the PCB over, so it seems like power is flowing through it - just not to the computer.
Does anyone here have experience with repairing these later PSUs, or replacing them with an ATX power supply? Replacement PSUs of this model are about $45 on eBay, but I don't want to spend that much only to find out that there's a simpler/cheaper/more reliable solution out there.
Thanks!
