Power Consumption Tests
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 DS3R is slightly better than that of the DQ6; however DQ6's extra voltage regulation system will come in much better for overclocking and pressing the limits. The P45 systems though are able to use less power than the P35 system, meaning both Intel and GIGABYTE has managed to make more power conservation strives with their chipsets.
