Feature: 1. High-Speed PCIe 4.0 Extension Cable Compatibility: The gpu mounting bracket comes with a PCIe 4.0 extension high-speed cable compatible with most GPU/motherboard components, supporting PCIe 4.0/3.0/2.0/1.0 applications. For motherboards with PCI-E 4.0 specifications, enter the motherboard BIOS to manually set the PCI-E option to 4.0 (GEN4), ensuring optimal performance and compatibility. 2. Enhanced Performance with Shielding: 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 ensures your GPU operates at its without being compromised by external factors. 3. Optimal Cable Length and Connector Design for Easy Installation: The video card support kit is designed with a 15 cm cable length and a 90° female PCIe connector, minimizing cable strain and allowing for easy GPU installation in compatible cases. This thoughtful design caters to both functionality and aesthetic, ensuring a seamless fit within your system. 4. Sleek, Flat, and Foldable Cable Design for Efficient Management: With its slim, flat, and foldable design, the gpu bracket holder ensures efficient transmission, stability, and easy cable management within your setup. This design not only improves the internal look of your PC but also enhances airflow, contributing to a cooler and more efficient system environment. Transmission Speed Considerations for Maximum Compatibility: The gpu mount graphic card bracket's performance is subject to the compatibility between the motherboard and the graphics card. It's important to note that the actual transmission speed match the lower version of either the PCI-E graphics card or the motherboard's PCI-E 16X slot (e.g., if the PCI-E graphics card is 3.0 and the motherboard's PCI-E 16X is 4.0, the actual transmission speed be 3.0, and vice ), ensuring users are aware of their system's capabilities for optimal performance.
