Hey guys, right now I got UPS that is about 4 years old. It's been starting to act up on me, like beeping and not turning on, so I think I have too much stuff plugged into it. I unplugged everything, but the computer, and would plug in everything after it would stay on. So I was thinking about upgrading it, but is it really that important to have a UPS? I don't really care about the battery back up anymore, and I just use it as an AVR. So I am kind of wondering is an AVR that important, or does the PSU in your computer handle all that for you? Thanks.
