Hello all, Been a hell of a long time since i've posted here. Haven't had a proper rig for nigh on 3 years and finally decided i wanted to get back in to tech. With that being said... I'm having issues with random restarts during gaming, and only ever gaming. I can run Furmark, Prime95 or both and not experience this however i load up WoT, Homeworld Remastered - whatever game and after 20 - 30 mins i lose power and rig restarts. Specs: MSI B360 Gaming Plus i3-8350k @ 4.0Ghz (no OC) Team Group Vulcan T-Force 8GB 2400Mhz Palit GeForce 1070ti Kolink KL-850M 850W 80 Plus Bronze Modular I've done all the usual checks with mem test, swapping out RAM sticks to different ports, scanned my HDDs for faults. It originally came to light when i had the card overclocked and in Homeworld Remastered using the Star Trek Continuum mod with all settings high, when the Starbase exploded a lot of effects happend and explosions and it kicked the PC off and restarted. It was only a modest overclock but unfortunately benching and overclocking was the first thing i did when i built the system so im unsure if the problem existed pre-overclock. The only way i can stop it happening so far is to reduce the power and thermals on my GPU using MSI afterburner. Seems like the PSU is struggling to power the GPU when at 100%, but i cant help thinking maybe the GPU could be wonky. Just looking for opinions. Unfortunately i don't have another PSU or GPU lying around to test but i am going to RMA the PSU. From what i've read they are actually not a bad brand, budget of course but Overclockers seem to recommend them and put them into their own builds.
