To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. The best way to get maximum load results is by using Furmark, and even though it is not indicative of a real world situation it shows the limits the card can theoretically demand. The ‘gaming’ results are measured when playing Crysis Warhead and is a more valuable result to take from this.
The power consumption figures of the GT430 are excellent, with it averaging around 37 watts when gaming. Under Furmark load it peaks around 50 watts, which is still very conservative and ideal for a media center environment. When KitGuru ran the world’s first ‘50 Watt Fermi‘ story back in May, we got a lot of stick from forums across the globe. After seeing the GTX480/470 cards, no one could believe that it was possible to get a Fermi product down to just 50 watts. nVidia has proven those critics wrong.
