We measured the power consumption with the system resting at the Windows 7 desktop, representing idle values.
The power consumption of our entire test system is measured at the wall while loading only the CPU using Prime95's Small FFTs setting. The rest of the system's components were operating in their idle states, hence the increased power consumption values (in comparison to the idle figures) are largely related to the load on the CPU and motherboard power delivery components.
Using the Core i5 variant of Intel's latest mainstream processor range, the Gladiator Sparta i5 4.40GHz overclocked bundle shows off excellent power consumption figures, even with its 1.350V CPU voltage applied.
