BUILT SEVERAL DAYS AGO, COMPUTER RESTARTING UNEXPECTEDLY HELP

[zachmartin1202]

So a few days ago, I built my first PC for gaming. It keeps restarting unexpectedly, but it only seems to happen while playing Guild Wars 2.
Here are my Specs:
CPU: AMD FX-8150 @ 3.6 Ghz
Motherboard: Asus M5A97
RAM: Corsair Vengeance 8gb DDR3 @ 1600 MHz
GPU: XFX Radeon 7850 2GB GDDR5
HDD: 1 Terabyte Seagate Barracuda Sata 6
PSU: Cooler Master Silent Pro 600W
CPU Cooler: Hyper 212 EVO

Does anyone know a solution to this? Is my power supply to low? If so, do you reccomend a higher one, for about 60-65 Dollars? Please help. Thanks.

Hi, thanks for the reply. I think heat is not an issue, for when I start BIOS after the restart, everything is at normal temp. That PSU tool is not very accurate, I know I need at least a 500w for just my GPU alone, and it recommends a 430w. Do you think a 700w would do the job? Also, do you know any memory test applications I can use to test my RAM? Thanks.
