Adding a Quadro into an R730

Hey all,

Anyone have experience adding a regular GPU into an R730? I was hoping to be able to add a Quadro K2000 into an R730 as a power user workstation. 

Questions I have are:

1) Is this possible to do in a 1CPU build, or do I have to do 2 CPUs?

2) Do I still need a dual PSU (will Dell software prevent bootup with 1 PSU and a GPU) even though the Quadro is only 51w max draw?

I know the GPU expansion kit is needed so I already have that in mind.

Thank you.
