Pc restarting when launching Pubg

[brentverelst1]

So i build a pc and everything worked out just fine, untill i installed pubg and my pc just instantly restarted.

i researched allot and i did all kind of tests with furmark, i tested my ram, nothing happened but the second i tried to test my pc with Prime 95 my pc restarted. i tried every test but they all restarted my pc, so can it be that my new psu ( evga supernova 750 P2 ) is a faulty one ? or can the problem be somewhere else still ?
I also tried to update drivers, reinstall windows 10 a couple of times so i'm pretty sure its not my drivers ( also tested the temps but everything seems just fine )
these are all my specs

GPU: gtx 1080 g1 gaming
psu: evga supernova 750 P2
cpu: intel core i7 7700k
ram: G.Skill DDR4 Ripjaws V 2x8GB 3000
cooling: noctua dh 15
motherboard: z270 gaming pro carbon
hard drive: samsung 850 evo 500 gb ssd
hard drive2: wd blue 1tb

If Furmark doesn't cause a restart, then the PSU shouldn't be the issue. You have an excellent CPU cooler; if the CPU temperatures are fine at full load, then the issue should either be the motherboard or the CPU. Did you run Intel Processor Diagnostic Tool?

What you found doesn't necessarily apply to your issue. To start with, you have a quality PSU with a single +12V rail. Unless it's highly overclocked, the CPU can't draw enough power from the PSU to cause reboots; besides stress testing the GPU doesn't cause a restart and it definitely draws more power than the CPU.

You think it's the PSU (test with another unit), but I suspect the motherboard (unstable VRM at full load). Tweaking voltages may help; you may be interested in threads like https://forum-en.msi.com/index.php?topic=283236.0
