I picked up a Cyberpower from buy.com pretty reasonable. Cyberpower at least offers a proprietary CLI package for Linux that seems to work well. Default setup powers down the PC on loss of power and then shuts down the UPS after a preset time. That worked flawlessly, though the shut down of the UPS will happen regardless of power restoration, but it powers back up immediately if power is restored. This is a bad thing if you sat here and turned your PC back on manually as I found out,
. But this is a good feature because my PC is setup to boot up on power. So the UPS powering up will cause the PC to boot up restoring the server functionality. I have since set it up to shut down when the battery hits 35%, though I didn't run it that long to verify that it works properly. Looks like I can get about 45 mintues with my dual core AMD system, ATI Radeon 4670, 19" Samsung LCD display, DSL modem and Linksys wifi. I also have a power station, gel cell battery in a case with A/C inverter, DC plug, and light, so in a long power outage I can shut down the desktop and use the UPS just for DSL modem and wifi router. Then use my power station to power the laptop so I could have internet for as long as AT&T's setup lasts. Worst case I have a small inverter I can plug in my truck in the garage to run electricity until that battery drops too much. For the hard core I ran Anderson power pole connectors off the back of the power station so I can plug in my ham radios here in the shack so I could stay on the air there as well.
