I came across an interesting article [ here ] that compared the power usage of various games consoles including the Wii, XBOX360, PS3 and PC using the [ Watt Up ] measuring device.
It made for interesting reading!
In an average period of gaming the Wii had "an 18 Watt average when playing what is considered the console's prettiest game! Compare that to the PC which hovers around 198 Watts steady, peaking around 209 Watts.
"While the PS3 had a lower minimum (probably due to the loading screen in between quarters in the basketball game), its average was about 13W higher than the XBOX 360 playing its most advanced game, Gears of War. GoW truly squeezes every little bit that the 360 has to give, and this is probably as much power any game today will require from it."
