We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).
The ASRock Fatal1ty P67 Professional does quite well with power consumption. I have to say that I am very impressed. Even overclocked we see very good power efficiency.
As a new measure, we are now monitoring the heat generation from the key components on the motherboard; this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.
Heat is also well within acceptable limits. Of course, with the massive board level cooling it should be.
