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).
Wow, the power consumption of the GA-H57-USB3 is pretty impressive at stock speeds and while we do see a pretty hefty increase when we overclock and add in the power hungry GTX 285, it is still not too bad.
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.
Remember how we talked about the layout and placement of the "Southbridge" components? - Well, here we are really seeing the results of that with a four + degree jump on an open system. The H57-USB3 also runs a tad warmer at stock due to the inclusion of the RAID function and also the Marvell SATA 3.0 Controller.
