Well my office has an APc one and i think we are running around 8 computers......back up is good and so is its functioning. Maybe the best would be to call them up and let them assess your requirements.

When I bought my last APC UPS I phoned their local office and they put me in touch with their Agent for my area and this person was extremely helpful. Gave me a lot of info and a contact of where I could buy the UPS.
