... than the 21.5 machines, but does anyone know how much bigger a power-eater the i5 or i7 machines would be under average load (browsing, emails etc)?

Maximum continuous power: 241W (21.5-inch models); 365W (27-inch models)

The 365W number is from Apple's Spec sheet for ALL of the 27" models so I would think that the max draw from a 27" would be 365 watts. That is most likely the i7. Others would then be less of course

I assume this too, and that rating is for when the machine is under maximum load. Has anyone measured their machines when idle / under light load to determine how power-hungry they are? The 21.5 units are amazingly energy efficient, and I wonder if the 27 inchers aren't far behind.
 
I remember reading that there can be an almost 100 watt difference between the screen on full power and screen fully dimmed so a lot of it may be to do with lighting all 27 inches of display at full power....
 
Im running 14 safari windows, using itunes and downloading at 150 kb/s. My external fantom hard drive is also plugged into my ups backup. It shows between 92 and 101 watts. The load goes down to 0 watts when the computer is in sleep mode. That doesn't seem very accurate to me. The APS backup is about a week old. Maybe its faulty?
