For those who have a dual core PowerMac G5, what do you use for a battery backups? I want to get one that has enough load capacity to support a 2.3 GHz Dual Core PowerMac G5 and also a 20" Aluminum Apple Cinema Display. The one I have now just doesn't cut it at all. Its only a BackUPS 350. I live out in the sticks where brown outs and total power loss is frequent in the summer months and when stormy.

I just don't want to spend $500 or whatever on a battery backups when I only needed to spend $200 for example.

I just recently purchased an APC BX1300 UPS from CircuitCity for $130. I'm using a dual 2.66 mac pro. I'm not sure how the wattage of the G5 compares to the Mac Pro, but my system only uses around 250watts when sitting idle. The max for the UPS is 760.

OSX supports the APC ones natively, no software required.
Yes, I just bought from Best Buy the APC XS 900 UPS. The Software said it was good for OSX 10.4.1, but nothing about Intel or .10

Well, I plugged in the USB cable from the UPS to my Mac Pro, and the power settings read it automatically, so I didn't need to use the software.

It's pretty slick. It reads the battery charge level, and also can be set to turn off your machine at a certain time on battery, percent of battery left, or battery time left.

I set mine to shut down when the battery is at 50%, which I figure is long enough for me to shut things down myself, or if I am asleep at night, short enough that it won't stay on too long.
