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 power draw at idle on the XPower is very impressive compared to the other boards in our test group. When we put the system under load, things change quickly, though.
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.
The heat generated by the X58 chipset is not that much compared to what we saw from the average X48.
