Computer Shuts Down When Playing Games

[Takaron]

Hello Everyone,
Any help would be greatly appreciated.
I've been having this issue ever since I bought my PC two years ago where it will randomly shut down as if someone has pulled the plug while playing games.
Some games seem exempt from this issue such as counter strike and skyrim where this issue has never happened, however games that have been released recently such as GTA 5 and Player Unknown's Battlegrounds, the PC shuts down frequently.
The timing of the shut down is completely random, for example I have been playing Battlegrounds for a week without experiencing a shut down, but yesterday it shut down twice and has shut down once this morning.

My PC specs are:
Cpu = i7-4790K
Coller = Cooler Master Hyper 212 Evo
Mobo = Asus Maximus VII Hero
RAM = Crucial Ballistix Sport 16GB
GPU = MSI GTX 970
PSU = XFX 650W 80+ Bronze
HHD & SSD = 1GB of SSD / 3TB of HHD
Case = NZXT Phantom with 1 front supply fan and 2 back extract fans

Any help would be greatly appreciated, Thanks in advance

One more thing - go to nvidia control panel > manage 3d settings > global settings > power management mode, and change to 'prefer maximum performance'

Then select the program settings tab and select mad max from the drop down, and change the power management mode to 'prefer maximum performance' as well.

Well.. I updated the bios and have managed to play mad max on very high for about an hour without it turning off.. Think you might of solved it!! Can't quite believe it, must of been a fault or something in the BIOS, i don't really know haha. Thanks so much for your help though, I owe you one!!
