I have an opus 90W powering a M10000. Over the last week, it has been randomly deciding to power up or not power up when i start the car.
Today it wouldn't power up at all - in fact the green status LED was not even blinking. So i checked all wiring, fuses and voltages to find nothing out of the ordinary. I repeatedly unpluged the opus input power cable to attempt to check things and diagnose the problem, but it didn't help.

It wasn't until i unplugged the ATX power cable from the mobo that something must have got "reset" and when it was all plugged back in, it worked - the PC came out of hibernation at the same spot it left off.

I wonder if it was an opus thing or a m10000 problem? I hope it will continue to work now
