I built my system a year ago and the last month or so I've been getting problems playing graphics intense games where the system will just restart. The time this takes seems to be faster for graphics intense games like the witcher 3 (30s) than killing floor 2 (up to 1 hour).

All my temperatures (cpu, gpu, system) are low while playing and so I don't think it's an issue with cooling. Nothing is overclocked. There must be something else going on. I'm inclined to believe that my PSU is slowly dieing, especially since this problem seems to be getting worse affecting less intense games.

What do you think?

System Specs:

PSU: EVGA 550G2 Supernova 550W
CPU: i5-6600K
GPU: Zotac 1080GTX AMP
RAM: 16GB
OS: Windows 10
