Hey guys,
I’ve been having random restarts and GPU driver crashes when playing certain games. I tested my PSU (MSI MAG A650BN, 650W Bronze) with a PSU tester and got a Power Good (PG) value of 90 ms.

From what I’ve read, the ATX spec is 100–500 ms, and the ideal range is around 250–350 ms, so mine seems a bit low.
Could that actually be the cause of my system instability?

Here’s what I’ve noticed:

GPU driver sometimes crashes and recovers, sometimes causes a full restart

After restart, audio switches from headphones to monitor speakers

I’ve already done DDU, clean Windows install, BIOS update, etc.

Everything points to the PSU at this point. Do you guys think I should RMA it since it’s still under warranty?

Thanks in advance 🙏
