My dual G5 2.5 gets here in just hours according to FedEx tracking. I also have two 20" Cinema displays. I need to know what UPS is beefy enough to handle the load of this 700W power-supply machine and these (low wattage) screens. Any suggestions?
Thanks.

says it handles 900W
Look at the thread in this forum "Problems with refurb.", about halfway down the thread for what I was told about it.
Sorry I can't be of more help! Seems I'm in the market for one myself, so more opinions would be awesome for me as well.

Remember that 700W is the absolute maximum power draw (we used to refer to this as the ILS value - If Lightening Strikes it will draw 700W). Although a powerful system it doesn't draw a tremendous amount of power under normal conditions.
I have my dual 2GHz on an 800VA Belkin "Universal UPS" and the UPS is reporting that it is 30% loaded. This is without the display connected to the UPS (the CPU and display are in different rooms).
I have one of the 1500VA CyberPower boxes on my servers and like it a lot. I have 3 Intel P4 boxes, a 2.0 G5, 17" LCD, and all of my networking gear [switches, router, wireless] on it. It's reporting just under a 50% load.
The cyberpower software is Mac compatible and provides a lot of useful info about the UPS load, voltages, run time, temperature, etc. I haven't used the Mac software yet, but this is the information provided by the Windoze software.
APC's software is Mac compatible, but only provides the ability to shut down your system if the power outage is extended. Note that their higher-end UPSs and software have a lot more functionality and are a lot more expensive.
Belkin's software is Mac compatible and gives you basic information about the state of the UPS (load, voltages, etc).
A good rule of thumb for a happy UPS is never to load it more than about 60%.

I use APC Smart UPSes.
Get a Kill-A-Watt, and see how much power your G5 uses. It'll tell you wattage and VA. Make sure you run the G5 hard when you check, since that's how much power it can draw.

I had a 500va ups and my G5 alone (with NOTHING else plugged in to the ups) peaked it (forced shutdown)... so I might need a larger one. Right now I'm working off of a serious power strip in lieu of a good UPS...

Don't try to outweird me, I get stranger things than you free with my breakfast cereal.

that was me and what I own. : ) I have my dual G5 and 21" monitor and cable modem
and router and 1 clock plugged into it. When power goes out (and it does here in PA
a good amount because of lightning) it handles all that stuff no problem and lasts about
35 minutes before you get a low battery warning. Software works great in OSX.
