750w PSU enough?

post #1 of 5
Thread Starter 
for 2 6870's in crossfire, i7 2700k (all at stock speeds for now), P8Z68-V pro/gen3 motherboard, 4x4gb 1600mhz ram, 1 SSD, 2 WD Green Sata drives (1&2TB respectively), and 5 case fans?

Reason I ask is because I seem to have shoddy luck with my desktop lately with random lock ups requiring a hard shut down (sometimes while idle) every now and then. my psu that i'm using is a Seasonic Gold certified 750w PSU with 62 amps on the 12v rail.

i just replaced my old motherboard (gigabyte z68xp-ud3p) due to boot cycling with the latest iteration of it not even getting me to the POST screen after removing the cmos battery and leaving it out overnight before i began testing it earlier this morning with no success.

750W is A LOT of power, it should be more than sufficient to support your system, check your RAM, maybe its defective, check your motherboard, and check your software configuration
