Computer restarting erraticaly - help

  ????? ???? 09:20 20 Dec 2016

Hi, My computer automatically restarts all the time. I then get an error message on restart: Power surge detected on previous powerup. Power surge protection activated to prevent damage from faulty PSU.

Have tried replacing cable. No large electronics kicking in or anything. Power draw on the PSU is well under Max spec. A while ago ASUS bios was showing 3.3v rail as red drawing ~2.9V.

Specs: I5-3450 MOBO: ASUS P8H61-M LX PSU: Seasonic S12II-620

Have you tried borrowing another PSU to plug in and see if that fixes the problem? That way you can isolate the PSU as the cause of the issue.
