Hiya,
I recently got a new GPU, a GTX 760 from KFA. I installed it today and while playing Planetside 2 my computer suddenly rebooted. All of my drivers and everything is up to date. I wasn't monitoring the temperatures at the time but I will from now on to see if it happens again. However, in the meantime, I was wondering if it could be a PSU issue. I have a very new Corsair CS550 Modular 550W. Am I right in thinking that the PSU isn't the problem here? A quick google will tell me 550W should be enough, however, I also read that the modular types can be a bit more unsteady so I thought I'd ask the experts (that's you).

In case it matters I'm sitting on an Asrock Z77 Pro4-M and an i5 3570K. Everything is stock settings.

Thanks.
