It's not just the power outages which aren't so bad. They are annoying and can cause you to lose work, and in some occasions corrupt your HD, sure; but it's the surges, lightening and unstable AC that can ruin a PC and a UPS will protect against these by using a constant filtered uninterruptible power source. (I use a Belkin F6C120-UNV, 1200VA 670 watt, plus a separate smaller IBM unit for my periph's). -Clint
God Bless Clint Hamilton, Owner http://OrpheusComputing.com ----- Original Message ----- From: <[EMAIL PROTECTED]> Harold: Sorry that I confused you and I am sure, many others. Why not call APC at 1-800-800-4272 and ask for a brochure. I am sure that their explanation will clear up the confusion. You could also go to their web site at www.apc.com I believe that any computer that draws power from an AC line should have one of these units protecting it from power loss, whether it is momentary or long term. They provide temporary power for saving any work in progress on the computer when the AC line power fails. Some of the units provide a program that will automatically do this for you when a power failure is detected. I was particularly impressed with the unit's ability to "self start" and provide power under isolated conditions. Then they become a portable power source.
