Mine is doing 30 mhs at 92w, at least according to teamredminer. Maybe it's drawing more from the wall, but I don't have a watt meter to check.
Man, don't you feel sorry for spending $ 10 on a wattmeter. Electricity consumption also depends on the certification of the Bronze-Platinum power supply unit and the motherboard.
I have old GA-970A-DS3P motherboards and they consume 20 watts more than new ones.
