I think the 2500watt ones are actually 1400 watts on 110 and they are 2500
watts when you run them on 220. I cant remember for sure. I know the 3000
watt ones work like that. We run 3000 watt with the 2500 in non redundant
mode. You can do a show power to see how many watts you have. If you have a
fan-2 and a sup720 (they eat up like 1800 watts for those two alone)and any
cards you are going to need to run it on 220 with 2 power supplies either
redundant or non redundant.
