    I need to take a pair of G5 dual 2.0s on a field trip. They both have the 6800 ultra DDL card and will run two 30" screens each... I am not an electrical engineer, but I really want to know if I can power both of them with a Honda Eu2000i generator going through a line conditioner and a UPS. The Honda kicks out 2000 watts and is rated at 13.7 amps. For safety sake I would like to be a couple of amps below it's redline rating....

    PowerMac G5 2.0 Rev A 170W low power 325W full tilt
    6800 card 100W (guess if the 9800XT is 75W)
    30" LCD 150W

    The Rev B will be a bit less.

    OK. Rad. Does that mean I just use the w=VA formula?

    Figure 600 watts per machine... line conditioner takes 25%... so
    each machine works out to: 600w=(120v)(5a).... 5amps/machine
    the amps after conditioner: 10.13

    so one should do it? are my calculations correct?

    Make sure you check with both the line conditioner and the UPS manufacturer that they are compatible with generator power and each other. There was a bruhaha years ago about chaining one type of UPS after another (ferroresonant? Can't remember now) that resulted in damaging effects.

    I had a customer once who discovered they couldn't use their UPSses off a generator for a fairground display.

    Thanks... and good point.

    I am trying to figure out if I can use Monster's stuff or if I have to go to something more industrial.
