600VA UPS
Experts,
I was thinking to place two desktop computers on a 600VA UPS with 15 mins backup time. The reason for this is to save on cost as I only need to 10 seconds backup time before the generator would kick in. Is there any concern with this setup?
I calculated the watts and each CPU needs 280watts, LCD needs 300watts. Current voltage is 220v.

If I exceeded the real power of 480watts and backup time is 15 mins on full load, I'm assuming the back up time will reduce in half? Or I have this all wrong and the UPS will not work?

The actual run time will depend on how much power - in watts - you're drawing, and we have no way of knowing that. However, I'd wager you could run two computers off the UPS for 15 seconds. You can test this by plugging in all the equipment to the UPS, then unplugging the UPS from the wall and timing how long the equipment runs on battery only.

Exclude the monitors from using the UPS battery. Plug them in to the surge protection portion of the UPS.
For what it is worth the PF of switching power supplies is much higher than .8 but that is academic in this scenario.
Plug both computers in, unplug and test. If it works GREAT! If not... Get two ;-)

and also check if you don't exceed the output current of the UPS
the startup current could be a problem; but only 1 way to know = test
