PCIE 4.0: Over 64GB/s (bi directional) true PCIe 4.0 performance riser, backward compatible with PCIE 3.0/PCIE 2.0/PCIE 1.0 through shielded very high speed wires and dedicated power cables for lossless signals over the range. 3. 180 DEGREE: GPU riser cable features a slim, flat and collapsible Approx. 200mm/7.87in design, 180 degree, plug and play, compatible with most GPU and motherboard components, fits most cases. 4. TEMPERATURE REDUCTION: Unique independent channel shielding to prevent external EMI/RFI and interference between channels, segmented design allows airflow and reduces operating temperature for GPU, M.2 NVMe SSD. 5. INSTALLATION: Please install the riser cable to the GPU before securing the GPU with I/O brackets. Please do not use screws to install the TT P8 chassis (the GPU can still be secured with the two screws on the PCIE slot inside the chassis). Specification: Item Type: PCIE 4.0 16x Extreme Flexible Material: PCB Color: Black Interface: PCIE 4.0 X16 Male PCIE 4.0 X16 180° Female. Package List: 1 x PCIE 4.0 16x Extreme Flexible Note: It is not recommended to use screws to connect riser cables. Some cases may have misaligned screw holes, which may cause the GPU to deviate during installation, resulting in damage to the GPU and system.
