Need help with reboots when gaming! Possible PSU issue?

[blujadajhdja]

I already made a thread about this (not sure if it's spam), but that thread has died with no one responding and I have learned a lot more about the situation now anyway.

My PC will reboot itself when gaming. I can web browse the whole day without any problem, but as soon as I load up Planetside 2 or play a different game for 1 minute, it will reboot itself.

Upon rebooting, my monitor will stay black and my motherboard will display a debug code: 62. I checked the manual and found that 62 meant chipset initialization error and that I need to reset CMOS (which I have done multiple times already).

I know for certain that nothing is overheating. I have ran the Windows Memory Diagnostic and have found no errors. I have run sfc /scannow, chkdsk, and am certain that all my drivers (and BIOS) is up to date. I have the latest Windows Updates.

Event Viewer just shows Event 41 signifying that the shutdown is unexpected and Windows has no idea what happened.

I'm planning on doing an RMA on my power supply, but I'm not sure if this is the best route to take.

Rig Specs (nothing is overclocked):
4790k with H100i
ASRock Z97 Extreme6
Corsair Vengeance 16 GB 1600mhz
MSI R9 290X Gaming 4G
Corsair HX850 80+ Gold
Samsung 840 EVO 250GB
1TB WD Black
1TB WD Red

I just ran it and it got through the whole benchmark without crashing.

Also, I ran Planetside 2 for about 2 minutes before it rebooted.

I'm going to try to refresh Windows and see if it helps.
