BF4 PC Shuts off during gameplay

[Stone04]

After playing Battlefield 4 for about 10-15 mins my computer abruptly shuts off as though the power was cut.
My specs:

Windows 7 64 Bit

PSU - Corsair TX850
MB - Gigabyte 990 FXA UD3
CPU - AMD FX-8350 @ 4.0GHz ~ Not overclocked
GFX - Gigabyte AMD Radeon R9 280X ~ Not overclocked
RAM - 2x 8GB Corsair Vengeance @ 2400MHz
Case - Aerocool xPredator with all 6x 120cm fans + 2x 180cm fans.

Please help me out here I can't get more than one game in without a crash.

i've experienced something similar, my pc also shutted down when i was playing and even totally powered off so i had to switch the on/off switch on the psu and it appeared to be the psu not feeling so well, if the psu can't deliver enough power it will just shut off the pc, that's what happened on me, but could be something else wrong though
