I'm running a Dual 2.7 GHz PowerMac G5 and a 20" Cinema Display. Ideally I'd like to have about 15 minutes at least of battery backup for these two pieces. Anyone know what kind of specs I should be looking for? I'm completely clueless here and thought the forum might be able to save me from having to learn all about it.  | ryanflucas

I'd check out APC. I have two of their Backup-UPS BR800 Models that have been running well for years. The batteries are user replaceable and tend to last 5-7 years before you need to replace them. Some things to note though:
-- What devices are going to be backed up and which only need surge. The system & display would be on backup, while accessories would be on the surge. The battery backup units often have a built in surge and then a few backup only ports. Printers aren't placed on backup because of their high drain. I usually place my computer, display, and cable modem on backup.
-- Automatic shutdown. Not sure if this is Mac compatible, I assume it is on the APC models, but most backup units interface to the machine via usb and can auto shut down the computer in case the power goes out for long periods of time.
-- Ethernet protection. I've never heard of or experienced a surge over ethernet, but some units have this as a ethernet pass-thru option.
My biggest reason for getting a backup was the brownouts occurring in my area. A blackout is full power just going out while a brownout is when the power doesn't go out but falls to like half capacity so there isn't enough to fully power your devices. This is the worst kind because it can kill electronics that expect to be fully powered. While any backup unit can compensate for lack of power if this happens, not all of them had specific brownout protection. I had to call APC and buy a specific unit online instead of locally because most local stores sold brownout free models since it shaved about $30 off the retail price. This online tool worked really well in determining which models had enough capacity. Don't let their prices bother you though, just get the model numbers and then shop around online for the best price. | savior
