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).
Okay, something is wrong here. The GB board is pulling significantly more than we would have expected, even with the Phenom II X4 965 in place.
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 not too bad on the GB 890PGA-UD3H. It was even under control when we dropped in the HD 5870.
