Thanks, Mac. Very helpful.

My UPS is older than the PC I built, and it worked fine on my prior PC. The next UPS I get will be higher rated.

What fooled me was the change in design of the Antec 'green' power supplies, due to what they called 'power factor correction', that absolutely WILL draw 1.25 times the rated output power. This apparently is new. Now that I understand that, choosing the next UPS will be easy. Double derated = thanks!

Out of curiosity, what are the problems with buying one that is rated too high (besides than the extra cost)? Doesn't respond as fast?
