High-speed and reliable signal transmission: The PCI-E 4.0 riser cable is designed with a high-quality hand-soldered gold pin, ensuring maximum conductivity and signal integrity. The imported cables with pure copper tinned cores offer stable and almost attenuation-free signal transmission, allowing for full-speed and reliable data transfer. Compatibility and maximum transfer speed: The imported silver-plated cable supports up to 64GBS, complying with the PCIE 4.0 transmission standard. It is also backward compatible, ensuring compatibility with a wide range of graphics cards. This high transfer speed allows for fast and efficient data processing and rendering. Enhanced power supply for high-power graphics cards: The GPU riser cable features an enhanced 12V power supply with a 12PIN silver-plated cable, specifically designed to meet the power requirements of high-power graphics cards such as RTX4090, RTX3090ti, and RX6900XT. This ensures stable and reliable power delivery to the graphics card for optimal performance. Improved cooling and airflow: The segmented design of the GPU riser cable allows for improved airflow within the system. This enables better heat dissipation, reducing the operating temperature of the graphics card and other components. By maintaining lower temperatures, the overall system performance and longevity are enhanced. User-friendly and durable design: The GPU extension cable is designed to be plug-and-play, eliminating the need for any BIOS setup. It also features a unique cable protector that enhances the durability of the extender and prevents cable damage. Even if the cable is folded or twisted, it maintains the best connectivity and lifespan, ensuring a reliable and long-lasting connection for your graphics card.
