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).
Surprisingly the AMD 890GX uses more power than the H57 does. But, to its credit it is doing this with a much more power hungry CPU. This means that overall the board is actually better for power consumption than the H57 board we tested it against.
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.
There is no way else to say it, unfortunately the 890GX still generates more heat than the H57 does even when overclocked.
