MINUTEMAN UPS Entrust 500VA/300W (Installation Equipment / Line and Power Protection)

Compact tower physical form. Easy to setup. Connects to computer via USB. Has 8 outlets - 4 providing backup and surge protect, 4 with surge protect only. Also has RJ45 protection. Software user interface is good overall. Some of the software controls/selections are not very intuitive and could use some redesign. You can figure them out though while you are getting familiar with the unit/software. I am using this on a stand-alone system consisting of a computer, monitor, and router that are backed-up and other equipment on the surge only section. The combined load for the backed-up equipment is 22-30% of the UPS rating. This gives me plenty of back-up time (about 15-18 minutes)and allows for the UPS to shut down the computer as the time ticks away (how much time is needed to shutdown your computer is user selectable) following a power failure. The UPS/software does have some advanced notification features that I am not using, so I have not rated it on those. So far, so good after one week. No actual power failures, but I have tested it via the software and by removing power. Here is the minuteman web site: [..] for further info as I could not find a lot of info or reviews prior to purchasing other than directly from the mfg.

Provides excellent protection in case of power outage for systems we use. I highly recommend this as inexpensive insurance in today's technology environment.
