PowerColor HD 5750 Go Green
 

PowerColor has engineered a unique HD 5750. Their Go! Green Edition is completely fanless using a big passive heatsink, it also works without additional PCI-Express power connector, a configuration which limits the card to 75W maximum power draw. Considering that the AMD reference design requires 92W, PowerColor had quite a way to go. Did they succeed? http://www.techpowerup.com/reviews/P..._5750_Go_Green
