If you have a server and you care about it..... Avoid anything under $750 that is a SIMULATED sine wave/ You need a REAL double conversion sine wave output. This assures clean power and will extend the life of your server and, especially, the PSU. Right now, I'm trying an inexpensive unit that has two servers, my cable modem, network switches, etc connected. However, I haven't tried to control it. (It requires an additional card for SNMP) Once I have SNMP, I can use my monitoring system to send a text and shut it down. *shrug* I would like to have a working UPS system that does that. :-) It does have both serial and USB. http://www.opti-ups.com/index.asp?SCID=SC12080131 I got the 2kVA unit with 1400 watts. (My servers only have a total of 20 disks and they run AMD processors, Gold PSUs, etc.) Make sure you take a quick power calculation to make sure that you have enough room to grow. Also, if you need more time, they have connectable battery packs. Also, each of them come with desk side and rack mount options. It has been working solid for over six months. P.
