Hello I am lost. I have tried everything possible. My mac pro suddenly stopped working. Shut down normally, went to restart power button led started flashing. So i did all the diagnostics possible that I know of, removing ram and gpu. Exchanging it with working ones still nothing. I need also some help trying to narrow down my issue. Is it the motherboard or the power supply. The rest have been tested and working. Need some help please.
If you have a multimeter, I’d recommend pulling out the PSU and bridging the two pins like the guy shows in this video, then check for 12v on the huge power rails that come off it. If that isn’t present, that would be your issue https://www.youtube.com/watch?v=ihYukqmC…
