Well, if you look at published figures for the Xeon CPUs, it seems to  
match that very well.

Also, a couple of reviews of the Mac Pro 2.66 quad core unit showed  
power usage when working around 220 watts, so I believe these figures  
are accurate.

The reason my machine shows more power usage is because I have an 8800  
graphics card, and 8GB of RAM, so my power usage is higher.

The main drawback of the Mac Pro is idle power usage.

The newer Xeon CPUs use a lot less power than the older ones, but it  
appears that they cannot slow down their clock like other Intel CPUs.

Either that, or Apple just didn't include support for that.

Of course, the Mac Pro sleeps almost instantly, and uses 7W then.
