HIS has designed a full size card that is mostly covered by the large passive heatsink.
The card requires two slots in your system, while this is more than other HD 5550 cards, it is necessary due to the passive heatsink design. See how the heatsink looks like a flying bird?
The card has one DVI port, one HDMI port and one DisplayPort. The HDMI interface includes a 7.1 channel audio signal that is generated by an HD audio device integrated in the GPU. Unlike NVIDIA cards which limit you to two active outputs at the same time, you may use all three outputs at the same time on ATI's latest cards.
A CrossFire connector is not present, but you may add another HD 5550 to run in CrossFire. In this case all the CrossFire data will be transferred via the PCI-Express bus.
Here are the front and the back of the card, high-res versions are also available (front, back). If you choose to use these images for voltmods etc, please include a link back to this site or let us post your article.
