Question PSU +5V output seemingly capped to 3.192V

[Ashtyn]

Hi there,

Just over a month ago I installed a new PSU and GPU (Corsair RM850x and GTX 3080 Ti) into an admittedly lower-end MOBO (AsRock B450M AC r2.0). I have had no performance issues or anything, but out of nowhere I noticed today that while playing a game for about 30 mins, HWiNFO shows my 5V rail is horribly underperforming or being misreported. Please see the below screenshot for reference. I know AsRock apparently has a problem with their motherboards misrepresenting certain power sensors, but this just seems odd that my 5V would be underperforming this badly and have zero variance in voltage.

Thanks!

What does the Bios say about those voltages?

or being misreported

This. If 5v really is 3,192v the system would shut down.

The best way to test your PSU is to use an ATX power tester with LCD display so that you can see the precise voltage info.
