The Sapphire ATI Radeon HD 5850 TOXIC is slightly longer than the reference design HD 5850, by about half an inch. Gone are the bat nostrils (boo!), but the rear facing dual 2x3pin PCIe power connectors remain. Two dual-link DVI-I connectors are present on the rear of the card, as well as HDMI and DisplayPort outputs. The dual height card retains the stock backplane arrangement of outputs and small heat vent.

The blower style fan is replaced with a more traditional ball-bearing axial fan, center mounted in the smart blue and black shroud covering the copper and aluminum vapor-chamber cooler. The design is quieter and cooler than the reference design HD 5850.
Sapphire has equipped the HD 5850 Toxic with their patent-pending Black Diamond chokes, to deliver greater power efficiency, cooler than standard designs. As you can see below, that extra board real estate is used to good effect for the extra, high performance components. The Sapphire HD 5850 TOXIC is more than just a bios flashed stock HD 5850.

TOXIC & Reference Design
The Sapphire ATI Radeon HD 5850 TOXIC supports CrossfireX with two bridge connector slots, using up to four discrete cards with the appropriate AMD 790FX motherboard. A 500W quality power supply with two 75W 6-pin PCIe power connectors is recommended for single card use, and 600W with four 75W 6-pin PCIe power connectors recommended for dual card use.
Three display ATI Eyefinity is also supported, requiring the use of the onboard DisplayPort for the third display. If your third display doesn't support DisplayPort, you can use the Sapphire Active DisplayPort adapter to connect your third DVI monitor.
