Power consumption and temps

The power numbers reflect the complete system's, evaluated by using a watt meter attached to a single socket. 65W for a full mid-range PC is excellent, and 145W when playing Crysis Warhead isn't too shabby either.

The Sapphire HD 5670 Ultimate manages to beat out the actively-cooled HD 5770 in the temperature tests - not bad for a card that's allergic to fans. Firing an infra-red temperature gun over the larger section of the heatsink resulted in a maximum temp of 51°C, by the way.

But what about giving it some multimedia action to contend with? We hooked up a Pioneer Blu-ray drive and noted temperature and system-wide power-draw over a 10-minute playing of The Dark Knight. Temps averaged 48°C while power-draw hummed along at 86W.
