Power Consumption

Hereby we take the power consumption under load as well as idle. To generate a load situation we use SiSoft Sandra's Burn-In Module and measure the whole systems power consumption. The values we take when the System just booted into Windows and the load drops.

Idle	Consumption	Percent
Intel Core i5 2500K 3.30 GHz DDR3-1333 (Intel Graphics HD3000)	45 Watt	34.62 %
