The PCI-E 4.0 riser cable adopts high-quality hand-soldered gold pins, allowing for maximum conductivity and ensuring signal integrity. It utilizes imported cables with pure copper tinned cores, providing full-speed, stable, and almost attenuation-free signal transmission. The imported silver-plated cable supports up to 64GBS, in line with the PCI-E 4.0 transmission standard, while remaining backward compatible with maximum transfer speeds. An enhanced 12V power supply with a 12PIN silver-plated cable delivers 12V to meet the needs of high-power graphics cards like the 3090. With a segmented design, this GPU riser cable allows for airflow, making it easy to reduce operating temperature and improve overall system performance. It is plug and play, requiring no BIOS setup. Featuring a unique cable protector, it effectively enhances the durability of the extender and prevents cable damage, even if the extender is folded or twisted. This GPU extension cable provides the best connectivity and lifespan.
