100CM PCIe 4.0 OCuLink SFF-8611 Male to U.2/U.3 SFF-8639 Female NVMe SSD Extension Cable with SATA 15Pin Power, High-Speed PCI-Express Storage Dongle for Motherboard NVMe Backplane, Limited Stock

This 100cm OCuLink SFF-8611 to U.2 SFF-8639 extension cable is a professional high-speed PCIe 4.0 storage interconnect cable for desktop workstations and enterprise rack servers, equipped with integrated SATA 15Pin power supply wiring to solve insufficient power issues for high-performance NVMe SSDs.

One end adopts SFF-8611 4i 38Pin OCuLink male connector to plug into motherboard OCuLink header or OCuLink RAID adapter cards; the other end is SFF-8639 U.2/U.3 female port compatible with all 2.5-inch U.2 NVMe solid state drives. The attached SATA 15Pin power branch provides steady power output to support drive hot-swap detection and 24/7 continuous heavy read-write workloads.

Constructed with high-purity shielded copper conductors and precision impedance matching, it eliminates electromagnetic interference and signal loss during long-distance transmission, maintaining stable low-latency NVMe performance. Braided nylon cable jacket reduces internal wiring clutter and improves heat dissipation inside compact server enclosures.

Reinforced locking latches deliver anti-vibration tight contact to avoid loose connection failures caused by rack vibration. Plug-and-play without extra drivers, fully compatible with Windows, Linux and mainstream server operating systems. Limited stock available, widely used for motherboard NVMe storage expansion, high-speed workstation cache upgrade and server U.2 backplane deployment projects.
