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.
Power consumption is surprisingly good, averaging around 118 watts when gaming. When using Furmark, this rises to 161 watts, which is slightly more than the Sapphire FleX Edition we reviewed last month.
