Being a dual-slot card, the NVIDIA Tesla K20c draws power from 1x 6-pin + 1x 8-pin power connector, with power draw rated at 225 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Tesla K20c is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution.
