Enhanced Shielding for stable performance: Our 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 ensure your GPU operates at its without being compromised by external factors. 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 allowing for easy GPU installation in compatible cases. This thoughtful design caters to both functionality and aesthetics, ensuring a seamless fit within your system. Speed PCIe 4.0 Extension Cable Compatibility: The gpu mounting bracket comes with a PCIe 4.0 extension speed cable compatible with most GPU/motherboard components, supporting PCIe 4.0/3.0/2.0/1.0 applications. For motherboards with PCIE 4.0 specifications, enter the motherboard BIOS to manually set the PCIE option to 4.0 (GEN4), ensuring performance and compatibility. Use scenarios In compact or crowded cases, the 15 cm extension and 90degree connector help route cables cleanly, reduce strain on the GPU, and maintain a neat build without obstructing other components. In systems with limited space behind the motherboard tray or in vertical GPU setups, the design supports easy installation and secure mounting while preserving airflow and aesthetics. When configuring a system to leverage PCIe 4.0, use the PCIe 4.0 extension cable and enable GEN4 in the motherboard BIOS to ensure maximum compatibility and performance across PCIe generations.
