Sony’s PlayStation 3 uses a massive 380W of power, more than the average desktop computer, and far more than the 45W power need of the PS2. The PS3 uses more than twice the amount of power as the Xbox360 at 160W. This means that playing your PS3 console two hours a day will cost you an extra $80 a year. Most will probably spend far more than two hours; playing games, watching Blu-ray movies, surfing the net etc. The average PS3 owner can expect to add another $100-$150 extra on their yearly electricity bill.
