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.
All three boards have just about identical power usage. MSI consumes just a wee bit more power, whilst the ZOTAC and XFX are clones of each other.
As a new measure, we are now monitoring the heat generation from the key components on the motherboards, 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.
MSI's heat-pipe design allows it to cool better than NVIDIA's reference design, and since that's what both ZOTAC and XFX use, they equal each other out.
