AMD has successfully engineered the Radeon HD 4850's power budget to be able to work with a single slot cooler.
The card has two DVI ports, basically the most common output configuration these days. In case you need an analog VGA port you can use the included DVI adapter. When using an HDMI adapter (not included!!), you will also have access to HDMI+HDCP+Audio, which allows easy setup of a media PC. A new feature of the Radeon HD 4xxx Series is that 7.1 audio is now supported, the previous cards supported only 5.1 audio with HDMI.
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.
