(Speaking from my own experience over the last 15 years)
If you have two desktop PCs plus monitor and switches I would try to get
1500VA or more.
I have tried Tripp-Lite, Cyberpower, and APC. So far, the best luck I've
had is with APC.
I started out with APC initially (small unit, 350VA) and paid the
premium price. The second and third time around (not replacing, needing
new UPSs) I tried other brands. First the Tripp-Lite, it was OK but a
year and a half later it just died with no warning. Got a replacement
battery and still no go. So I bought a Cyberpower UPS. This one lasted
almost two years, and when the power went out the first time it worked -
but the second time it went out when the power came back the UPS fried
and it unfortunately took out my PSU, motherboard, and hard drive. For
some reason the monitor survived... and no, I did not have any
high-amperage devices attached (printer is in a different room.)
Anyway, after that experience, I stuck with APC. I currently have four
of them, a little 350VA guy for my modem and switches, and 3 1200VA
models. These are old now, bought in 2004, and other than having to
change one battery in one of the units, they all still work. Nine years!
I also recommend APC based on my own experience. Yes, they're more
expensive (in some cases 50% more) than others, but longevity seems to
be great. Plus you can use apcupsd for monitoring in linux.
We also use APC at work. While a few have had their batteries changed,
most of the units themselves are at least 10 years old.
