Power Consumption

We performed our power consumption measurements using an Extech Power Analyzer 380803. This device is connected before the PSU and measures the power draw of the entire system (without the monitor), including the power loss that occurs in the PSU itself. In the idle mode we start the system up and wait until it stops accessing the hard disk. Then we use LinX to load the CPU. For a more illustrative picture there are graphs that show how the computer power consumption grows up depending on the number of active execution threads in LinX. All mainboards on the diagrams are sorted in alphabetical order.

We were not surprised to see that Foxconn P67A-S mainboard turned out to be pretty energy-efficient compared with the other testing participants, because it was the only mainboard that couldn’t increase the processor Vcore and therefore has to sacrifice its performance instead. However, in nominal mode things are a little more contradicting. Foxconn mainboard is the most energy-efficient in idle mode, it boasts average power consumption in single-threaded applications, but it turned out the most power-hungry during maximum CPU utilization: it was the only mainboard to consume over 140 W of power.


It must have been wrong to use the same approach to Foxconn P67A-S mainboard as we applied to all other contemporary Intel P67 Express based mainboards. In reality it turned out incomparable with them in functionality, being inferior in many aspects even to some entry-level mainboards on Intel H67 Express, which are incapable of overclocking at all. Moreover, out of those few overclocking-related options that the board has, the most important ones didn’t work properly.

The proprietary software from Foxconn also makes a pretty sad impression. It is hopelessly outdated in both: interface as well as functionality. This mainboard is obviously targeted for those who do not overclock or fine-tune their systems and prefer nominal mode with default settings. In this respect, the mainboard has every chance for popularity. Pretty rich functionality of the Intel P67 Express chipset has been extended even further with additional controllers providing support for USB 3.0, PATA and eSATA. Very low price of this mainboard is yet another appealing feature that will encourage the demand.
