There won't be one from Dell, as these cards are much newer than that system.  I doubt you'll find one off the shelf, either-- given the proprietary power supply.  You'd have to find one with the correct sockets and work out the pin assignments you need.

@ejn63​ It's on their spec sheet as compatible though.  There has to be one.  I read that its similar to what the T7920 uses as well.

@DELL-Joey C Hi Joey, can you please provide your expertise on this?  Kindly requesting the cable and part number for connecting an RTX 5000 GPU to the Dell R7920 / T7920.  Believe its the PCIe 8-pin → 12VHPWR cable.  Look forward to hearing your thoughts.  Thank you! : )

To anyone that this could help in the future:  Think we found the solution and waiting for them to get in.

Will use 1x Nvidia "12VHPWR 12+4Pin to 2x8Pin(6+2P) Power Adapter Cable for RTX 40xx" with 2x Dell TR5TP 6-pin + 6/8-pin power cables to support the GPU.  Will know for sure when we get them in.  Take care.
