7 Watts

My sleeping MacPro with 6 gigs of fully buffered dimms, 4 hard drives, and 4 cores consumes only 7 watts of power. This is really amazing to me because it goes to sleep instantly and wakes almost instantly. It doesn't appear to be dumping ram to the hard drive so the ram is being refreshed. 7 watts? Really? That's low, low, low. An AppleTV's "sleep" mode is twice that!
