Fantastic value. Unit provides lots of rock-solid power. A single Xeon server has over 100 minutes of battery. Another unit I have is powering two powerful desktops and they have over 40 minutes of battery. Stands allow for great vertical installtion. Rack mount is great as well. Lots of cables provided for monitoring. Software runs fine on Windows Server 2003 and shuts server down safely when battery is close to running out.

Pure sine, double-converted online output is the best. Enermax specifies real sine wave (not simulated sine) UPS' for their Infiniti and Galaxy PSU's and the SU-series do it well. It's quick switching to battery power when AC is down and the software works. Can accept external batteries for increased runtime. Internal heat sinks are nice - keeps things cool should you happen to use full 800 watt capacity, but most PC's never use that much even at full tilt. I have an o/c'ed E6600 & HD2900XT, 3 HDD's, 2 opticals, etc. and the output LED's haven't gone past 50%.

Great for larger power supplies that need continuous power. Expensive for a standard workstation. But if you have dedicated graphics and running a high end power supply this cost is just easily justified.
