15cm PCIe 4.0 M.2 M-Key to OCuLink SFF-8611/SFF-8612 Host Cable, 2280 NGFF Adapter Wire for NVMe U.2 SSD & External eGPU

This 15-centimeter short adapter cable features a standard 2280 NGFF M.2 M-Key plug on one side and an OCuLink male connector compatible with both SFF-8611 and SFF-8612 host ports on the other side, supporting PCIe 4.0 x4 full bandwidth for high-performance peripheral expansion.

It enables users to convert internal M.2 NVMe slots to OCuLink external ports, widely applied to link U.2 NVMe SSD enclosures, external eGPU graphics cards and portable high-speed storage docks. High-purity tinned copper internal conductors with integrated double shielding effectively block electromagnetic crosstalk, maintaining consistent signal integrity during intensive read/write and graphics rendering workloads.

The ultra-short 15cm length eliminates redundant tangled wiring inside mini ITX, compact workstations and laptops. Precision molded anti-reverse housing prevents wrong insertion, while reinforced connector locks avoid loose contact from vibration. Compatible with mainstream motherboards, mini servers and eGPU docking devices, ideal for DIY high-speed storage expansion, external graphics setup and portable NVMe drive deployment.
