Blackout with overclock

Once again, I must bow to the collective wisdom that is Tom's Hardware.

GPU: EVGA Gtx 670
PSU: Corsair HX-850
Mobo: Asus P8Z77-V Pro/Thunderbolt
CPU: i7 3770k OC @ 4.6Ghz 1.260v

The graphics card will run completely fine not overclocked, but when I turn the OC on and the card starts to ramp up to full voltage and speed, I'll get a random shut down. No warning, no artifacts, nothing. The entire PC will just shut down. Any ideas what this could be? The only thing I could think of is that the PSU is faulty and isn't delivering enough power.

This isn't really a detrimental problem, as it will run fine without the OC, but its like having a BMW S1000R, and not being able to take it over 12000 rpm

Any thoughts on this would be great.

Thanks,

John

Yes, that mostly caused by PSU...

have you checked all of the cable..? maybe some cables make short..
whether all cables installed properly?
and
How old your psu..?

if it's new and you already check all cables..then it's must be defective one...

Try to rma your psu..

The cables all appear to be plugged in properly. The PSU is less than a month old. Is there any way to check the PSU without sending it in?

the easiest way is
Borrow your friend's psu, and try in your system..

if system running well, then your psu is the problem..


double check it with try your psu in your friend's system..
just make sure that your friend's computer is heavy enough to make some load to your psu (HX-850),
and see..whether the same issues persist..?
