Mac Pro 3,1 Fans On Won't Chime Nor Boot
Replaced the power supply. No drives, no RAM, no pci cards, no video cards, no DVD reader/writer. I plug in the power cord, and it powers up, fans spin normal, front LED is solid white. Nothing else. Battery checks ~3.0V.
Not sure what to do. Unplugged it several times, drained the power supply with ~10s front boot button pressed. Sat overnight unplugged several times.
LEDs showing nothing. It’s in my garage, around 5°C, so it’s not overheating instantly on power-up.
Any insight what to do? I’m at a loss. Cheers

Got a chime out of it with some RAM that is indeed needed. That was a misleader. Still working on this.
