I once had a PSU fail catastrophically- arcing, visible from around a corner and down a hall, and quite loud. I didn’t want to go near it, circuit breakers were closer anyway, but I didn’t know which one so I just hit them all. Once replaced, I fired up the machine and… I think the cmos was cleared, but other than that, no ill effects.
Also never cheap out on the PSU. If your shit PSU dies, it might fry every component in your PC, if your good PSU dies, you can just replace it.
