I have not run the system in a few months so I closed the circuit breaker and turned the key only to be greeted with absolutely no life from the front panel, but the Power Control Bus did respond and powered up the drives.
Cycled the key a few more times and I got life and weirdly no complaints about unstable voltage rails or any problems at all. Ran it for two hours and cycled the key to test something and it was stone dead again, save for the peripherals.
Took the lid off and there's no fans and no DC rails coming up at all according to the LED's. Left it over night in case this was some weird pseudo indication recap time was approaching and this morning it was still no better.
Where should I start troubleshooting the power supply? It obviously has standby power for the Power Control Bus.
