As long as the power supply can provide the following, you are relatively on the safe side: 1. The UPS provides a pure sine wave power supply 2. The UPS is not of the line-interactive design type, as is with the Back-Up UPSs 3. The UPS is double conversion so that if there is a fluctuation in power, the battery takes over like there was no fluctuation and so the server does not "feel" the fluctuation at all 4. Your best bet would be an online UPS therefore
