Power Consumption

We measured the power consumption using Extech Power Analyzer 380803 device. This device was connected before the system PSU, i.e. it measured the power consumption of the entire system without the monitor, including the power losses that occur in the PSU itself. When we took the power readings in idle mode, the system was completely idle: there were even no requests sent to the hard drive at that time. We used LinX program to load the Intel Core i7-860 CPU. For more illustrative picture we created a graph showing the power consumption growth depending on the increase in CPU utilization as the number of active computational threads in LinX changed in nominal mode as well as during overclocking. For comparison purposes we also included the results for Asus P7P55D Deluxe mainboard, because it is a pretty typical representative of the LGA1156 mainboard family in terms of power consumption readings.

ASRock P55 Deluxe mainboard shows pretty good results in nominal mode as well as during overclocking. It has either the same power consumption as Asus P7P55D Deluxe, or even lower one.
