I'm looking for a UPS solution for a Server and Network gear. The server is a Dell PowerEdge T610 and has one 570W non-redundant power supply. Network gear includes a desktop computer (for VOIP) probably has a 250W-350W power supply, a T1 modem, 2 switches (one of them is POE). Any advice would be highly appreciated. My budget is $500 Here are a few that I'm considering.
