Do I need a UPS?

I know I could ask in some hardware subreddit, but I'm curious to know what people with multiple GPUs and expensive inference setups think about this.

I just moved to a new place and here the lights go out pretty frequently. 3 times over the last week, I came back to my computer being off due to a blackout (I guess it's a blackout, the entire neighborhood looses light for a few seconds/minutes). I have a desktop computer with 2x RTX5080s.

Do I need to buy a UPS to protect my computer from this? I get mixed answers about this topic. I don't mind my workflows being interrupted when the computer turns off, the only thing I'm worried about is the hardware being damaged. I have a good PSU, is that enough to protect the hardware?
