What else will you be protecting and how long do you want it to run for in the event of a power outage?

I will be using a SB6120 Motorola Modem ( input voltage 12vdc 0.75A ) and the i3 21.5 iMac and only info on the Mac that I can find is of course 120 volts and 241 Watts Maximum continuous power and last a external harddrive a Iomega ( input voltage 12vdc 1.5A ). Apple website does not mention the amps but if I remember my formula it is 241 watts divided by 120 volts = 2.0 AMPS . I do not have the iMac yet and if I did I could provided info from the mac. I figure no more than 15 minutes at the best. I just want enough time to shut down computer with out being rushed. We have had more and more power outages lately in my area for the past couple of years. Mostly when it is a perfectly good day that might last a few minutes to hours. Thank you for any information you and others might give or suggest.

I bet that would put me in the poor house for sure just with the electricity bill. Can't imagine how much that would cost me. Had a good laugh with that one. Thanks alot residentEvil, I needed that!

I'm sure good advice on this subject is elsewhere.

Add up the number of watts for everything you'll power with a single UPS. Multiply that number by 1.4. Choose a UPS that has a Volt-Amp rating of at least the result of that multiplication. UPSs are marketed by their VA rating, which is typically 1.4 times the Watt rating the device will support. So a 500VA unit will provide 350 Watts (350 X 1.4 = 500). I always go high; if my requirements are for 200 Watts (280 VA) I get a 350VA unit. This provides slightly more duration of battery support, and allows for less than maximum load on the device, reducing strain and theoretically extending its lifespan.

I'd suggest the APC Back-UPS 650 for about $85.
