To put some perspective here, let me post this wikipedia info

http://en.wikipedia.org/wiki/Xbox_360_hardware#List_of_revisions

 

Codename	CPU	GPU	HDMI	Power Supply	In Production	Date Released
Xenon	90 nm	90 nm	No	203 W	No	November 2005
Zephyr	90 nm	90 nm	Yes	203 W	No	July 2007
Falcon	65 nm	90 nm	Yes	175 W	No	Late September 2007
Opus	65 nm	90 nm	No	175 W	No	June 2008
Jasper	65 nm	65 nm	Yes	150 W	No	September 2008
Trinity (Valhalla)	45 nm (combined "Vejle" chip)[27]	Yes	135 W	No	June 2010
Corona	45 nm (combined chip)[28]	Yes	115 W	Yes	August 2011

The first Xbox360 used +200W and the newest one, with all the optimizations, the single chip for both the CPU and GPU, etc still uses more than 100W.

Even including the efficency of the power supply, that's still a lot.

I'd also like to note that just because the Power supply is rated at a certain spec doesn't mean that is actually what the entire system draws.   In fact, you really don't want it running too close to peak at all.   A 20% headroom is about ideal for a console.
