I've recently bought a new 20" iMac, and I got curious about how much electricity it consumes. Searching Apple's support pages turns up this article: http://support.apple.com/kb/HT3559 which gives numbers for power consumption at idle (59.7 W) and CPU max (87.8 W) for this model. Good first step. But I'm hoping to find some more detailed information. How do those numbers break down between display, CPU, disk, etc.? A practical question is, if the display does to sleep but the CPU is still idling, what then? Can anyone point me towards more detailed info? Thanks!
