Dell T420 GPU Power Cable

Hi All,

I am needing some help finding a power cable to install a GPU in my Dell T420. The GPU I have is a Nvidia GTX 1080TI. I would need and 8x8 pin cord and a 8x6 pin connector for power supplies. Does Dell have a part that would work with the GPU that is available? Is there anything else out there that would work?

Thanks in advance.
