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).
At idle the Sabertooth X58 has some excellent power usage numbers. Under load things do change considerably as everything kicks in and starts demanding its share of power from the wall.
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.
One of the advertised features of the Sabertooth is the CeraM!X heatsink coating. According to the PR write up this should "dissipate heat better with its microscopic irregular surface". As you can see from our readings, this was not necessarily that case; we can say that it had a low delta between idle and load at stock speeds, but again things broke down when we overclocked the system.
