I have This APC battery backup. My 50" LCD RP, denon 3808, Xbox360, PS3 and DVR are all plugged into the battery backup outlets. I have my ep500 plugged into one of the surge suppression only outlets. The unit is set to turn on my ep500 and my cinema quest bias light behind the TV when my receiver is turned on.

If I have all of the components running I am pulling 550 or so watts from the wall (but am pretty sure that does not count the ep500 or light- only stuff plugged into the battery enabled outlets)
