Sapphire HD 5770 Flex Edition comes with non-reference cooling that’s pretty quiet during operation. The card is almost 19cm long and, as you can see from the picture, the cooler takes up two slots.
You’ll find a large heatsink with two heatpipes underneath the fan. These pipes start directly above the GPU and end up on the opposite ends of the heatsink. The heatpipes are 8mm ones and they do a good job in transferring heat.
You can see the memory through the heatsink. The memory is cooled only by air from the fan, which is usual for entry level and mid-range products.
Sapphire HD 5770 Flex Edition offers a plethora of video outs. The card comes with two DVI outs - one dual-link DVI with 2560x1600 support and a single-link DVI with 1920x1200 support. Note that the single-link DVI is painted grey for easier recognition. DisplayPort also supports 2560x1600 so users can go for two 2560x1600 displays.
Sapphire HD 5770 Flex Edition is unique in a way where it supports three displays using only DVI and HDMI connectors. This should be pretty handy as the third display on AMD’s cards previously required either active DisplayPort adapter or an actual DisplayPort display. If you decide to use the HD 5770 Flex Edition’s included DisplayPort however, then you can use up to four displays.
The card comes with two CrossFire connectors and is powered via a single 6-pin power connector.
