Power Consumption Tests
Using our new PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly referred to by our readers, we are now able to find out what kind of power is being used by our test system along with 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 inevitably going to be higher.
The massive overclock only draws an extra couple of watts both at idle and under load.
