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 HIS card is taking a little more power than the reference design although it is only a few Watts more under load. It is worth pointing out that when playing a game the power drain is significantly lower than 217 watts. Crysis Warhead for instance only demanded 140w at maximum settings. Furmark is purely synthetic but interesting regardless.
