Thanks to everyone for your replies. Ideally, I'd like something that can provide power for the maximum length of the longest outage so far, about 2 hours 40 minutes. I have to balance that with what I'm able to spend on one of these. So, I'm willing to be content with running things long enough for the system to shut down. I've only been investigating units which have widely spaced outlets for wall warts. I'm also ok with 5-6 outlets being battery powered, and the rest just having surge protection. I've been specifically avoiding units which say they have an lcd for easier configuration and status. I had to make some guesses on how much everything I have would draw. The system itself is from around 2006. It used to be one of those windows media center machines before I got it, and turned it into a server. I'm guessing it draws 140-150W. Everything else I want to run off battery is just wall warts. There are four of those, I'm guessing 10-15W each. All together, that would place things at about 180-190W. The unit I have in mind supports up to 450W. So, that should give me 15-20 minutes run time, which I'm ok with, since most of the outages are within that range. If they go for longer, they're likely to be the close to three hours kind. Is there some way to calculate ballpark wattage without having someone read labels on everything I want to plug in? No, I don't have access to a multi-meter, accessible or otherwise. Do the figures I gave above look reasonable? Thanks again for the replies so far.
