Power Computing Systems and UPS Backups

I want to get a UPS backup for my computer, but I need to know how much power it draws so I can get the right one.
Backup supplies are typically only 65% efficient. To correct for this, a backup
needs to be able to supply 35% more power than the maximum capacity of a given
computer.

For example, the Power 100 and 120 units use 250W power supplies. Assuming that
any backup will only be 65% efficient, a backup system capable of supplying
337.5 watts or more would be needed. [250W x 135% (1.35) = 337.5W]
