PC shutting down unexpectedly

[Zakhri32]

Hey guys, so today I turn on my PC(Just build recently) and after I got to the Windows 8 login screen, my PC just turn off, I tried turning back on after around 5 minutes and it started working without turning back off, then while I was browsing the internet, I loaded up Star Wars Knights of The Old Republic MMO, 5-10 minutes into the game it turn off my PC, this happen twice since I tried it again and the 3rd time while I was playing I manage to get through 30 minutes without the PC shutting off, Is this the case of a bad PSU? I check all my temperatures and they are all normal, not overheating. My specs are on the side >>

Thanks in advanced

Re-insert cables back? My PC used to restart by itself in the past, i took out the 24-pin cable and realised it was loose. No problem since.

Nope didn't work, I build the PC from the ground up like 3 times and still it decides to shut off...

Guess I'll go RMA the PSU
