I just installed a R9 390 and a Cooler Master v750 to power my machine and anywhere from 20 minutes to 2 hours into gaming the entire thing just shuts off. I have to flip the switch on the PSU to get it to power back on. I am not sure if it could be a graphics card issue or a PSU issue, or even an overheating issue. The CPU and the surrounding area including the North Bridge, get up into the upper 50's while gaming. I'm not over clocking anything so I am at a complete loss for what's going on.

It is never happened during normal use just gaming. Crashes most during Shadow of Mordor, handles Arkham Knight Ok.

CPU:AMD FX-8350
RAM: DDR3 1600
Board: ASRock 970 Performance
GPU: R9 390
HD: 1 SSD, 1 Sata 7200
PSU: Cooler Master V750


Please help,

thanks

None, however I have a temp gun on the back of the board and just behind the counter is getting 70 degrees Celsius. Not sure if that's normal, but if I can't find anything else I'm just gonna have to rma. Not sure what temp causes a shut down.

:wife's playing Mordor now and the MOSFETs by the CPU are over 75 degrees and rising
