PC Shutting down when using better graphics
Hey guys, So i recently upgraded my computer after 5 years and have been having quite a bit of problems with it since the parts arrived, but finally everything is plugged in properly and running smooth.
However, if i start playing a game at high settings after awhile my pc shuts down. At first i thought maybe my GPU was overheating, despite the 4 case fans plus the 3 on the card itself, but when i ran CPUID HWMonitor my card never went over 100 degrees.
I now think my poor 5 year old PSU isn't giving my card enough power to support the higher graphic settings, however I'm still new to building PC's and want some other opinions. Any help is appreciated!
