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).
Unusually for an AMD based product the ASRock 890GM Pro3 pulls quite a bit of power from the wall. We were more than a little surprised to see this even at stock speeds.
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 generation was also much higher than we expected; not terribly much, but we think that the shortened cooling might have something to do with this.
