Speed PCIe 4.0 Extension Cable Compatibility The gpu mounting bracket includes a PCIe 4.0 extension speed cable compatible with most GPU and motherboard components, supporting PCIe 4.0/3.0/2.0/1.0 applications. For motherboards with PCIE 4.0 specifications, enter the motherboard BIOS and set PCIE to 4.0 (GEN4) to ensure performance and compatibility. Cable Length and Connector Design for Easy Installation The video card support kit is designed with a 15 cm cable length and a 90degree female PCIe connector, minimizing cable strain and enabling easy GPU installation in compatible cases. This design balances functionality and aesthetics to ensure a seamless fit within your system. Enhanced Performance with Shielding The graphics card holder kit features a PCIe adapter cable made from the latest materials, offering effective shielding to prevent interference and performance degradation. This attention to detail helps your GPU operate at its without being compromised by external factors. Use scenarios In compact or small form factor builds, the 15 cm, 90degree connector allows clean routing and reliable GPU installation in tight spaces. In midtower or larger cases, the shielded PCIe extension helps maintain signal integrity while keeping cable management tidy. For systems using older GPUs or mixed PCIe generations, the universal compatibility of PCIe 4.0/3.0/2.0/1.0 supports flexible upgrades and stable performance across configurations.
