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).
The ASUS Rampage III Formula does well when it comes to power draw at stock speeds. Things do break down when we really push the board, but that is to be expected.
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 much more worrisome; at stock speeds we still see more heat generation than I would have liked. We suspected this when we saw the rather small heatsink for the X58 Northbridge.
