DL 585 G2- ok with single PSU, but both causing havoc.

Hi,
I have problem with 2nd hand HP 585 G2.
It has 2x 900W PSU, each one can work in every slot, each one when single does not cause any problem.

When I connect 2 at once, and boot the machine up, it goes through POST fine, until booting OS.
Then both leds PS1 and PS2 on diagnostic board start to blink ERRATICALLY.
Fans speed-up and slow down, it dies minute or an hour later.

Observation 1: been forcing the plug into PS1 causes less blinking on that PSU (!!!!)

Been swapping PSU's and cables and wall sockets aroung, still no joy.
Mains cables are NEW.

My suspicions:
1) it maybe the house wiring has no Protective Ground connected.
2) PSU C19 pins are visibly ok, but bit dimmed, not live coppper.

Please, please throw some hints, as I am running out of ideas.

Michal

Are you on a 20A circuit? I would definitely check for a ground and get one installed if missing. Is it plugged into a UPS?

Go get a $5 tester that shows ground, hot-neutral reversed, neutral-ground reversed. That server should be on at least a 20A circuit or 30A+ UPS.
