| AnthonyW86 said: The 75W is the rating of the power supply, it has nothing to do with the actual power consumption. A poer supply always has to have headroom and it also has to be able to recharge the controller and ppower other USB devices. This is from actual testing: http://www.anandtech.com/show/6465/nintendo-wii-u-teardown
''also took some power measurements on the Wii U. The system is powered by a 75W external power supply, but total system power consumption doesn't even hit half of that (at least with the games I tried):''
Other tests confirm power consumption in the 30W in games, and it's much lower than ps3 and X360: http://www.eurogamer.net/articles/digitalfoundry-wii-u-is-the-green-console

I'm aware.
They also need to take into account of capacitor aging, so gave it a little more headroom. - In-case you didn't know Power supply's actually loose efficiency and maximum wattage throughput due to capacitor aging, pretty much all devices actually have PSU's over-specced to their needs as it's not uncommon to loose 10% off the maximum wattage number over a long time frame.
Even the ambient temperature can effect the maximum wattage and how efficient a PSU is, it's always wise to over-engineer such a part.
With that said, a 70w PC GPU is comparably crap, especially one built at 40nm, the Wii U likely has something far inferior to that.
