I have a home theater in my basement, and I am in an area where the power goes out relatively frequently during the winter. I am thinking a battery backup is just about necessary for my projector, HTPC and (possibly) receiver, but I have no experience with battery backup systems. I did a little bit of research and tried doing some calculations, but I was just confused enough that I figured I should ask for help, so I wouldn't screw this up. Here is what I have...Acer H5360 Projector
Pioneer's Andrew Jones 5.1 Speaker Package
As for my HTPC, it is a gaming machine as well, so it draws a fair amount of power. From my research, it looks like this 600VA, 340W UPS would be just about the bare minimum for just my PC. Also, I am not looking to spend a lot of money, as I have a fairly inexpensive (cheap) setup, and nothing would be extremely expensive to replace. If I could get a UPS for under $200, I would be happy.
And now for the questions...
First, is a UPS really needed for a fairly cheap receiver/ speaker setup like mine? Would I likely be safe just using the UPS with the projector and HTPC?
Second, would most any UPS fit my needs? Can I go with a standard PC UPS, even though I will be using it on a projector as well?
Third, any suggestions for a UPS? I would like a bit of wiggle room, as I likely will be upgrading my projector soon, and may be adding a second video card to my HTPC at some point.
And for anyone who wants to get a feel for my PC power draw...
