All AMD Radeon  HD 5000 cards exhibit excellent power consumption numbers and better performance/Watt scores than any previous generation product from any company so far. So it is not surprising that the green folks have noticed these cards and started using them to keep their power usage down. Especially idle power consumption is important when a PC is running the whole day - usually sitting at the desktop or being used for desktop applications.Now PowerColor has released their HD 5750 Go! Green Edition, which does not use any active cooling (not sure why that is green, but I like it) and manages without an extra PCI-Express power connector. No external power available limits the card to a maximum power draw of 75W, which we will definitely check and try to surpass in our testing. Due to the completely passive design, PowerColor recommends that the card be installed only in a case where there is some airflow to supply the card with fresh air.
