PC Restarting when starting Far Cry 4

[EpicnessRo29]

So the title should be self-explaining. I start Far Cry 4 and my computer suddenly restarts but when I play The Division it works like a charm.

PC SPECS:

CPU: I5 4460 3,2 ghZ (No Overclock)

MB: Z97 AsRock PRO3

GPU : GTX 970 MSI Tiger Edition OC

PSU: SuperFlower SF-500P12N (2 rails one with 17A and one with 18A = ~31 A on 12V rail, Efficiency of 78% , 500W PSU)

Windows 7 Ultimate x64.

I hope it's not a PSU fault

I think it may be your PSU problem mate.

Ok, I can accept the idea but I can't understand why it's not restarting when playing another games like The Division? I've used HW Monitor and I've seen that there are same temps, same voltages , same wattage. Also even Uningine Valley didn't shut down my computer

run aida64 cpu stress test

tried reinstalling the game?

I'd start out doing a CPU and GPU stress test at the same time to stress it as much as possible and make it use absolute maximum power from the PSU. If it reboots during this, either your CPU is unstable, GPU is instable, but more likely: Your PSU is not up to the task.

 

That PSU looks kinda dogy, you should seriously try another PSU.

Umm I solved the problem. It was not the PSU. The CPU is using like 30W in full load and the GPU is staying at 90% wattage. The PSU is considered to be in class 2 in the list of quality PSU's. I've tried running FC4 after reassembly and now it works fine. I think the 2 molex to 6 pin adaptor was not plugged in correctly. Thanks though for help!

(I've ran FurMark and Aida 64 at the same time and it works perfectly!)
