Pro Max Tower T2 FCT2250 8-pin (6+2) GPU power cable part numbers

Hi,

We ordered a Pro Max Tower T2 FCT2250 without a discrete GPU and it came with two 12VHPWR (16-pin) GPU power cables.

We want to install an older GPU that has two 8-pin power sockets.

Does Dell sell an adapter with 12VHPWR socket to two 8-pin (or two 6+2 pin) plugs? Or does Dell sell a complete cable with 8-pin (or 6+2 pin) plugs at one end and the other end plugs into the PSU? If so, what are the part numbers?
