I recently upgraded to an RTX 3080Ti and every so often my computer does a hard shutdown. Temps seem to be fine and this didn't happen before with my Radeon RX 480 8gb. I'm thinking the 3080Ti is spiking power draw and tripping my old PSU that's about 10 years old. Happens when gaming at 4k and once at the desktop after rebooting from the hard shutdown. Should I replace my PSU? Any thoughts?
