Power Consumption Tests
Using our new PROVA Power Analyzer WM-01 or "Power Thingy" as it has become quickly known as to our readers, 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 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.
Rumors that the card sucks down the power weren't a lie either. At idle the card draws more power than any other model here and at load it's only slightly behind the dual GPU HD 5970.
In saying that, though, any good quality power supply would run the model with no dramas. A HX 620 from Corsair would be a great option or any other branded power supply over 600 Watt. You have to remember that we also do run only the basics when it comes to our test system.
