Default PC sudden shutdown and electrical buzzing noises during games

My PC suddenly shutdown and restarted itself the other day while I was playing Civilization VI. It was as if there was a power outage, but I have it connected to a UPS. Could it be my PSU? Also, it’s been making a lot of electrical buzzing noise during games for the past year or two, and seems to be getting worse. It is loud enough to hear every time I play a game, unless I use headphones. I assumed it’s annoying but harmless coil whine. Should I RMA? Is it dangerous to use in the mean time? It’s the only PSU I have (HX750 bought around 5 years ago).

Here’s a video I made to test whether it was my GPU or PSU making the noise. It gets louder when I move it down to the PSU.
