GPU Power Cables for A100 (8-pin).

Hello, I have an R750 server which is completely outfitted with the gpu enablement kit except it has the wrong gpu power connector for my A100 GPU. See here - it lists the enablement kits, the cables they come with, and the requirements for the A100. I have the DPHJ8 cable which is the 2+6, and as that link explains for the A100 I need the 8-pin cable (the 6+2 does not fit at all). Unfortunately the link there does not indicate the part number of the 8-pin cable or where I can buy it. Can someone help me track that down?
