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).
There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.
The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.
So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.
Power usage of the Rampage board is slightly better than the DQ6, but not by a huge amount. The Maximus gets a better power usage result due to the lower voltage of the DDR3 memory.
In a new test we use our IR Thermal Probe to measure the temperature of the Northbridge, Southbridge and Mosfets. This gives us an idea of how effective the cooling of the board is during both idle and load.
The DQ6 manages to keep a slightly cooler overall temp thanks to its larger heatsink profile and heatpipe assembly used, but in terms of longevity the extra couple of degrees certainly won't make much of a difference.
