Computer just randomly turns off, few mins or few hours of use.

What happens is, the screen goes black then the audio slowly starts cutting off, then nothing. I don't think its the GPU since the keyboard doesn't respond to num lock or caps lock.

Temperatures seem normal with CPU at 34-40 and mobo below 32. I don't overclock, using stock cooling.

My Build: http://pcpartpicker.com/p/zyztVn
6-7 month old build.

Are you sure?

This is the graphics card I have : https://us.msi.com/Graphics-card/GTX-960-2GD5T-OC.html#hero-overview

It says 120W power consumption
 


Plus, the CPU, and all other components, plus, when you stress the GPU, the power draw increases. If the PSU is low quality, it likely wont get close to the stated voltages/wattage without problems. If you had a tier 1 or 2 PSU, where the quality has been found to be much higher, you probably could have gotten away with such a low wattage. For your system, I would have gone with an EVGA 550w model from Tier 1 or 2.

I have played GTA for long time without problems. Played hours of Borderlands 2 on max. All 3 times the computer had the problem, I was watching Amazon Prime videos.
