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 CPU. First, let’s check the results in nominal mode:

In idle mode the power consumption of Foxconn A7DA 3.0 and Asus M4A78T-E mainboards is almost the same. Under heavy load Asus board proves a little more energy-efficient. And what will we see during overclocking?

Again things remained the same: the boards consume about the same amount of power in idle mode, and under maximum load Foxconn solution falls a little behind.
