Power Consumption, Noise Levels, And Temperature Readings
Power consumption is measured in watts for the complete test platform. The 2D value comes from a normal Windows user interface at idle (Aero is also turned off to establish a truly minimal value). The 3D value is measured when both CPU and graphics card are running under heavy load (to establish a peak value). The measurement comes from the wall socket, and the efficiency rating for the power supply we used averages around 82.4% (according to its vendor).
