Nvidia Quadro RTX Quick Start Manual page 13

For Quadro RTX 8000, RTX 6000, and RTX 5000, use the
8-pin to dual 6-pin auxiliary cable if the power supply
does not have a 6-pin auxiliary cable. Connecting a
single 8-pin or 6-pin auxiliary cable directly to the
graphics card is not recommended.
Note: Use the recommended power
connector guidelines at www.nvidia.com/
