Been looking at the CyberPower ones myself lately. If this is for a desktop
type box with an active PFC power supply go pure sine-wave. The higher the
efficiency rating of the power supply the more touchy they are wrt the non
pure sine wave variety. Almost all modern desktop power supplies today are
active PFC, so the pure sine-wave is becoming a 'must-have'.
