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 P7H57D-V EVO has great power usage. This is due in part to the EPU hardware and the EPU-6 software. Once you set this into Auto mode it can control the power consumption of every part of the board and reduce the energy draw when at idle. Unfortunately this only works with the all settings at Auto in the BIOS. If anything is set manually the EPU-6 software will run, but will put itself in high performance mode.
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.
The ASUS H57 board also does will in keeping the H57 chipset and other components cool, even with the GTX 285 on the board.
