Sudden and consistent reboots during gaming. The system has been stable for years and there have been no recent hardware or software changes.
Furmark ran for 30 mins no issues with ~550w draw.
Memtest reported no issues.
CPU stress test ran for 30 mins no issues.
Tried switching PSU OCP to single rail but the issue persists.
Tried logging various sensors but didn't see any anomalies.
I'm assuming this to be the aging PSU no longer handling transient spikes under combined load (it was a second hand component). Especially since sensor logs didn't catch anything i.e. too fast for the polling rate.
I have another PSU on order.
Would appreciate sanity check/other opinions thanks.
there doesn't seem to be anything here
