Well, what I did was look at the rating of the power supply in the PC, doubled
it, and got the next larger size UPS. That results in a load factor of about
40%, which should give about 20 minutes, (maybe more - never really tried it)
if the battery is good.
UPS manufacturers strongly recommend not to power scanners off the battery side
of the UPS (most UPSs have some outlets that are battery-protected, and other
outlets that are independant of the battery). Same for printers. The only
peripherals I have connected on the battery side of mine are the PC, monitor,
external modem, and external zip drive. These are the things that I want to
keep running in the event of a power failure (or even just a glitch).
Hope this helps.

UPS's are generally rated in VA

the "rule of thumb" i use is to simply multiply the VA rating times .6 to
get
the power rating...
thus a 600VA UPS should be good for 360 watts

all you need do is add up the power ratings of all the equipment that will
be on the UPS

for your particular setup a UPS rated at 600VA would probably work
OK...but to be on the safe side, i;d get at least the next size up

If you go to better UPS mfrs. sites, like APC, they have configurators which
will tell you what you need. Their recommendations are on the high side,
more than what you need.
