Power Consumption

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 890FXA is a pretty power hungry board. It was not the most greedy, but it was up there.

Heat Generation

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.

Despite the extra cooling the 890FX Northbridge got quite warm. This was due mostly to the amount of heat that the HD 5870 generates, saturating the Silent Pipe2. We are positive that if we had moved the GPU down (to the other x16 electrical slot) or used water we would have seen much better temps here.
