50cm PCIe 4.0 M.2 NVMe Extension Cable, NGFF M-Key SSD Extender Card with OCuLink SFF-8611 PCI-Express 4i Shielded Cord for High Speed NVMe Drive Internal Chassis Routing

This 50-centimeter PCIe 4.0 M.2 NVMe extension kit consists of an NGFF M-Key adapter board and an OCuLink SFF-8611 PCIe 4i high-speed transmission cable, specially designed to extend the motherboard M.2 slot outward for flexible SSD placement inside compact computer chassis, workstations and small servers.

It strictly follows PCIe 4.0 Gen4 x4 specification, delivering maximum 64Gbps ultra-high bandwidth to fully unlock the full read/write speed of flagship NVMe SSDs like Samsung 990 PRO, WD SN850X, Crucial T700 without bandwidth bottlenecks. Only M-Key NVMe M.2 drives are applicable; SATA protocol M.2 SSDs cannot be recognized.

The OCuLink SFF-8611 4i cable adopts multi-layer shielding and impedance-controlled wiring to resist electromagnetic interference from power supplies and graphics cards, ensuring error-free continuous data transmission. The extender PCB comes with reserved mounting holes for stable fixation, effectively solving heat dissipation and space layout problems when multiple hard drives are installed. Widely used for DIY PC building, content creation workstations, data storage expansion and industrial host hardware modification projects.
