Sorry to post twice, but I neglected to add to my first post that it does 
sound like you're reaching the limit of your power supply. (You don't say what 
it's rated at)
Here's a simple formula chart that I found in the April 2003 issue of PCWorld 
that might help:

CPU                             Wattage Range
       Celeron                      15-20
       Pentium II, III          20-30
       Pentium 4                  40-60
       AMD Athlon                 40-50
Motherboard                 20-30
128MB of RAM                  10-15
IDE hard drive                    5-15
SCSI hard drive               20-25
Floppy drive                    5
Optical drive                   15-25
Zip drive                         10
Graphics card
       2D                             5-10
3D with 16MB VRAM         20-30
Sound card                      7
Additional PCI card         5

Multiply calculated wattage by 1.3 to add a safety factor. I know that this 
is a "general" usage chart, but it's a starting point in configuring supply 
amounts for your UPS. Hope this helps.
