Recent installed GPU causing PC restart

[Apep]

I've done the base checks of the psu ETC.

I can start my pc and use it however whenever I start a game my pc just restarts, Ive checked the 12v and thats all running between 12.1 and 12.2. My psu being a 1kw unit I would presume its not the issue (detailed below just in case Ive bought a rubbish one). Ive updated my bios & drivers and I see no change.

Specs;
CPU: Intel 17 5820k 3.3Ghz
MotherBoard: Asus ROG Rampage V Extreme
RAM: Corsair LPX Vengence 3600mhz 4x8gb
GPU:Nvidia 1080TI MSI gaming x 11GB
PSU Novatech 1000w V2 Black Edition

When a PC/system reboots in the instant you tax it with a game, then the culprit is your PSU. What was your prior GPU? Unfortunately the PSU you have isn't on par with the list.

Prior to the 1080ti Ive had a 980 and a 1060 (3GB) both separate.

Thanks for the assistance i have now got a 700Watt Psu which works! 😀
