match ups with PSU.
So if u have a 450W PSU, typically u want a 450W ups on it.
Watts is not VA.... There is a conversion, so a 1000VA is more like a 600W UPS.
Blain says u want to get the largest u can afford, i support his recommendation because on a ups, in the battery backup side, if u exceed the wattage on the ups, you will cause the UPS to trip and shut off.
Matching the PSU Wattage with UPS is a good rule, because theoretically no one ever achieves 100% on any PSU.
If you would like to add additional stuff to the battery side on the ups... u should add 50W for every LED monitor... and 25W for a router/modem/powered USB HUB and 150W on a laser printer.

i think that depends on the battery.
Knowing gillbot and his electrical prowesss, which i rank much higher then mine, im sure those are deep cycle sealed acid batteries...
He's not the type to be stupid and overcharge his batteries causing them to explode... lol...
Thats more like my area of expertise... and i always get yelled by him at it.
