A good 500W PSU with 28A on 12v rails should be fine so Yes, 750W is good enough. What's temp when you are playing games? And is it a stable OC?
post #4 of 13
More then enough as people said already. If i shut down out of the blue, i would blame it on the OC not being stable

is not BSOD, it just shut off not crashing, not logging but just shut off.
I ran prime95 for an hour no crash, haven't get a chance to run longer yet =(

Need to run more like 4-6 hours to see what happens. Or check your BIOS. There may be an option that will trigger system shut down when the temp reaches certain level.

A random shutdown is definitely a sign of a power issue but you definitely have enough power being provided to the system.

Are you on a surge protector or a UPS? It's possible that there was a fluctuation in the power being supplied from the outlet.

It's also possible that you are unlucky and just have a bad PSU or even possibly a bad motherboard. Even reputable manufacturers put out a lemon every now and then.

Do you know which section it will be under on the mobo bios? (XFX 780I)

I will also change a surge protector =D

I don't have XPX 780i user manual here. You should see somehting similar this in your BIOS.
How's the load temp?
