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’s power consumption grows up depending on the number of active execution threads in LinX. The mainboards are sorted in alphabetical order on the diagrams.

The only aspect the Biostar TZ68K+ is blameless from is its power consumption. It is only inferior to the Gigabyte GA-Z68XP-UD3-iSSD in the overclocked and idle modes, but the gap is negligible. Otherwise, the Biostar is the most economical product in this test both at the default and overclocked frequencies.
