A few weeks ago, my apartment complex power started going on and off. Thank god I save my work frequently. However, I really want an extra sense of security. I'm looking for a good UPS for a reasonable price. My desktop runs off of a 450 watt PSU and a Dell 2005FPW. Does anyone have any recommendations? These things act as surge protectors too right? Side note: Does anyone use a power conditioner? I know many people use it for home theater, but I haven't heard much on computers. Is it overkill?
