Poweredge R730 and a nvidia GeFource GTX titan

Are there install instructions for a GeForce Titan into a Dell 730?   There is a connector mismatch and I don't want to fry the GPU. The PowerEdge has 3 connectors and the GPU has 2. I can fit the 3 connectors into the 2 but I'd like to make sure I do it correctly.

(the poweredge has 2 - 3x2 and 1 - 1x2, the GPU has a 3x2 and a 4x2 connector)

Thanks
