Gigabyte GeForce GTX 960 G1 Gaming 4GB review - Product Showcase

The card has six (!) display connectors, you'll spot three Display Port connectors, one HDMI 2.0 connector and two DVI connectors. HDMI is 2.0 compatible meaning that compatible monitors and tellys can do UHD at 60 Hz, DP is 1.2 but has support for eDP 1.4. Due to the use of this many connectors, there is no exhaust though, meaning all residual heat will be dumped inside the chassis. Sicne the card does not run really hot, that should not be an issue with a bit of internal ventilation inside your chassis.

At the top of the card you can see the two power headers, the reference boards will use a single 6-pin connector, Gigabyte gave the 2GB model a little more booty with two 6-pin power headers, this SKU however has one 6-pin and one 8-pin PCIE Graphics power header. So that's 75 Watts over the PCIe bus and 225 Watts over the connectors, that will be plenty for a nice overclock. A six phase power delivery is responsible for supplying the GPU and memory with power. 
 

The cooler is terrific really, the WindForce 3X Air cooling has capability up to 300W. The card doesn't even need half of that, so thermals and noise levels are incredibly low.
