Hello, my computer will restart when I try to play any sort of games.
I suspect it may be a power issue, because it's a pretty bad PSU.

TL;DR at the end

My Rig:
GPU: MSI GTX 970 Oc'ed*
CPU: Intel i5 4690K*
Motherboard: MSI Z87-G55*
RAM: 2x4gb 1800mhz Vengeance Memory
PSU: Power cool 80+ bronze PSU

Games that I have tested:
GTAV, Metro Last Light, Crysis and Cities: Skyline.

I used to have two 660's in SLI and every thing worked fine. Then I did all my upgrades and everything worked well for 2/3 weeks then the problem started to happen.
I noticed it first when playing Crysis 3 (Its unplayable can't get past the 3rdish level) and now all games are unplayable.

Going back to my old cards SLI does not work they both get power (Fan spins) but no option to go SLI. Just putting in one 660, everything works fine.


Heats perfectly fine CPU/GPU never goes above 60°C.
Stress testing the CPU, no problems as of now. Will Update

I have Underlined what I think are the most imporant bits

TL;DR version:
Something makes computer reboot when playing games could be PSU or GPU.
