Does plugging in Xbox 360 wireless receiver and controller to PC consume electricity?

[erik8thw]

My Xbox 360 wireless receiver and controller always plugged in to PC and the yellow LED lights are shown when my PC is running all the time. Do the yellow LED lights consume high electricity when my PC is running all the time?

Yes it consumes power, but nothing worth talking about.

Anything that needs to be plugged in will consume some amount of electricity but for something like that it's minimal. The receiver connects through USB so it's ran on +/-5V @ a certain current draw (<500mA or 0.5A). So even if it ran at a maximum current draw of 0.5A at 5V that's only 2.5W of power used which is very minimal.
