PowerColor HD 6850 PCS+ looks pretty nice and the hood seriously makes the card resemble the futuristic racing car pictured on the box. Actually it uses the cooler from bigger brother HD 6870 PSC+.
The HD 6870 PCS+ cooling is dual slot and the card is 22.5cm long. The fan is 9cm in diameter and is connected to the 3-pin connector. Fan speed regulation can be performed via the Catalyst Overdrive or any other tool you may prefer.
The I/O panel features one DisplayPort 1.2 connector, one HDMI 1.4a and two DVI connectors (one of them is single-link with maximum resolution of 1920x1200).
Just like the Radeon HD 6870, Radeon HD 6850 comes with only one CrossFire connector. This means that you can only use two cards in 2-way CrossFire.
HD 6850 PCS+'s heatsink uses three heatpipes to draw heat from the GPU core. The GDDR5 memory chips are made by Hynix (model number H5GQ1H24AFR-T2C). They are specified to run at 1250 MHz (effective 5000 MHz).
Radeon HD 6850 consumes 127W at max so it will require one 6-pin power connector. Software voltage control via I2C is not possible due to use of more cost effective voltage regulator uP6213.
