The RZ4-21B is a PCIe Gen 4.0 X16 flexible riser cable with a 180 degree plug and connector that is designed for sandwich layout SSF cases. The cable is 21cm long (excluding connectors) which is an ideal length for the DA6 but it can be used with any similar layout case.

The RZ4 is assembled using high quality cable and PCB to ensure a wide range of  compatibility with PCIe Gen4.0 motherboards and graphics cards.
