That's a lot of power. UPS's are sold as being rated in Watts, but are
really sold in VOLT-AMPS (VA). 800 Watts is 1131 VA. 

The conversion factor is 1.414 times Watts to equal VA and the other
way around is .707.

The units are always over rated anyway, so it is best to run your
UPS at about 1/2 of it's rated capacity.

I have a cheap UPS with a serial port so I won't recommend it.It's rated
at 800 "watts" (560 watts). It happily runs two PC type computers, a YES
MAX, a HOT set top box, a cable modem, a 16 port hub/switch, and a Cisco
ATA at 42% capacity.
