Tripp Lite by Eaton Digital LCD UPS Systems - Tower - USB - 10 x AC Power

This was a great upgrade from a smaller UPS. Now my NAS has time to recognize a power outage and actually shut down properly before the battery runs out! The unit was easy to install, and my Netgear ReadyNAS immediately recognized it and can monitor performance with no additional configuration.

This is for a powerful, yet dated, computer build. So much so that the unit that was replaced by this one (from a competitor) would give an alarm if the computer system was under a significant load. What I really like about this model is the readout on the front. Once one knows how, one can make the front readout give all kinds of useful information. Under full load, my computer system pulls ~550 watts. This unit handled it, no problem. One caveat, the plugs are very tightly compacted. As such, if one were to plug in a wall wart style plug, it may take more than one plugs worth of room. Thus blocking other outlets. Easily overcome by looking within your favorite e-retailer for "short extensions". Anything approximately 1 foot should do. Nature of the beast for such a small unit. On that subject, the footprint of this unit is very manageable. imagine a 2 slice toaster's width and height, and 2 toaster lengths. The unit didn't have too much time to settle in before its first test. As I was putting the unit through its paces, as it were, my wife came into the room to see if I had noticed the 10 second brownout that had just happened. As I had recently put the unit on silent, no I did not. Under full load, my monitor didn't even dim which, after some time in service on the competitor's model, it had. I've not had the unit long, but it seems to be working just fine. Time will tell. As such, time is on my side with the extensive insurance policy.
