I'm pretty sure this is a dumb question but I'm asking it anyway. I purchased an APC Battery Backup for my computers and its displaying the average load as 200w. This is with a Custom Built PC running idle, a 06 MBP on and idle, a 08 macbook idle, and a Samsung T260HD connected to the PC. Is this 200w continuous or per hour? It doesnt make sense to me. Does it mean im using just as much power as 3 1/2 60w light bulbs?
