how to install GPU in r750?

Hello, I want to install a GPU on the r750 server, but I have a few questions.

1. I looked up the list of GPUs that can be installed on the r750, is there any additional GPU that can be installed other than that link?

2. The r750 server does not have a power cable for GPU connections. I want to know how to connect.
(What additional cables should be purchased and how to connect them)

thank you
