30cm PCIe 4.0 M.2 M-Key OCuLink Extension Cable, 2280 NGFF NVMe to SFF-8611/SFF-8612 Host Adapter with Full-Height & Low-Profile Bracket, for External eGPU Dock & U.2 NVMe SSD Storage Expansion

This 30-centimeter M.2 NGFF M-Key to OCuLink extension cable is a compact PCIe 4.0 high-speed breakout adapter exclusively designed for 2280-size M-Key NVMe M.2 solid state drives. It converts native M.2 PCIe x4 lanes to standard OCuLink SFF-8611/SFF-8612 interface, breaking the internal bandwidth limitation of mini hosts, laptops and small form factor PCs.

Equipped with interchangeable full-height and low-profile metal mounting brackets, it can be firmly fixed inside mini PC chassis or notebook expansion compartments without loose shaking. High-purity shielded twinax copper conductors strictly follow PCIe 4.0 industrial specifications, delivering stable low-latency signal transmission under sustained heavy gaming, 3D rendering and video editing workloads.

Dual functional usage design: 1. Connect to OCuLink eGPU dock to add discrete external graphics for thin laptops and mini PCs; 2. Link SFF-8611/SFF-8612 to SFF-8639 U.2 cable for expanding high-speed NVMe SSD storage arrays. Gold-plated locking molded connectors provide tight anti-vibration contact to avoid intermittent connection failures.

Fully compatible with Windows, Linux mainstream operating systems, widely used for portable gaming device upgrade, content creation workstation graphics expansion, mini server NVMe storage cache extension and notebook external GPU deployment projects.
