Random PC Turn Off!!! on games!

[zeushunter]

Hi! this has became a bigger and bigger problem over time and I still dont know whats causing it.
I can play games like CS:GO Fine with 700 fps or so, I can play rust fine with like 200 Fps on high settings everything goes good, until about 5 mins into rust, and my whole computer just instantly turns off and restarts, I went onto real temp and got my temperatures and they mark at about 35*C while Im just sitting on the desktop. I will list my specs bellow! (This problem happens on graphics intenence games!)


: CPU:
: Intel Core i7 3770K clocked @ 3.50GHz
: RAM:
: 16.0GB Dual-Channel DDR3 clocked @ 1667MHz (9-9-9-24)
: Motherboard:
: Gigabite Z77X-D3H
: Graphics:
: NVIDIA GeForce GTX 780 Ti
: Storage:
: Seagate ST3000DM001-1CH166
: Optical Drives:
: ASUS BW-12B1ST a

Try testing different power supply, if possible.

And what are your temps whilst gaming?
Precisely what PSU do you have?

What is the make/model of your psu?

Is the fan on the GTX780ti clear of dust?

Corsair CX500M Power supply - 500 Watt Thats all I know!
and Yes it is clear!

500w may be too small for your graphics card.

Corsair CX is not that reliable and may have deteriorated over time.

I suggest you buy a better and stronger psu in the 600w range like Seasonic.
Assuming it solves the problem, RMA the corsair psu. Corsair is quite good at that.
When you get it back, sell it unopened on ebay.

On CS:GO My temperature was 45-50 degrees roughly

I have had this happen on 2 of my computers so far with no apparent cause (dust, overheating, etc.) and it has been the power supply failing. As far as I understand, the output filtering capacitors go a bit out of tolerance and the safety mechanism cuts power and then the computer restarts. If you check your event log, you may see an event id 41 error (https://support.microsoft.com/en-us/kb/2028504) and that is usually caused by power problems.

One time I had a bad hard drive that caused these type of restarts but that is a different story...
