UPS only keeps a computer and printer operational during a blackout. Do you need that? I don't need or want to continue using the computer during a blackout. My only concern is to avoid a sudden, catastrophic shutdown that could damage the hard drive(s) and save changes to files. Therefore, I want the UPS to provide power that lasts long enough to save open documents and shut down safely.
