The GeForce GTX 670 DC Mini has a maximum power consumption of 160 Watts (give or take a little), you'll need to power the card with one 8-pin PCIe PEG lead from your power supply. Power supply wise we recommend a 550 power supply to start with, with one card of course.
The GeForce GTX 670 PCB measures 17cm / 6.5 Inches in length with the cooler. Display outputs include two dual-link DVIs, one HDMI and one DisplayPort connector. The top part has been kept open for ventilation so that the card can exhaust hot air, the cooler design however will vent air into the chassis. Looking at the backside SMT traces show some empty DIMM spots, there could be a 4GB model as well. Here visible as well are two SLI connectors allowing for a wise variety in multi-GPU configurations.
Once the ambient air has been used to cool the GPU, the hot air will be blown only partially outside the PC through the exhaust, which you can see above the monitor connectors. However most of the heat will be blown into the chassis itself as the cooling casing is open at close to the PCB and rear side. Make sure you have proper ventilation inside the PC chassis, always.

ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with lower temperatures than reference GTX 760.
