Specs are in the sig, and I've got a 400w FSP psu. I used this psu calculator and came out to 351w. My psu is only 400w and lately I've been getting random reboots, never when the cpu is under load though. It's been stable for a while and I'm almost 100% positive my overclock is stable. I don't think its my overclock because it's been through almost 36 hours of orthos and 24 hours of memtest with no problem. It's not like a constant problem either it just comes and goes every once in a while.So time for a beefier psu or does my problem lay else where?
