Hello, I was using my UPS for my computer to protect it from surges and electric absence. Recently, about 75% of all time when plugged into UPS my PC gets stuck at the windows logo. So then I decided to try plugging the PSU into the wall outlet. It works fine, but like at night what if a surge goes into the computer since it's plugged into the wall outlet? Is it ok to turn off the PSU for the night every night? I am just worried that a surge might damage my PC at night..... or it doesn't help at all? Thanks in advance.
