50cm OCuLink SFF-8611 Male to U.2 U.3 SFF-8639 Female NVMe SSD Cable with 15Pin SATA Power, PCIe 4.0 Internal Storage Cable for Motherboard 2.5 NVMe Drives

This 50cm OCuLink adapter cable is engineered to connect motherboards, OCuLink RAID or HBA expansion cards with SFF-8611 ports to U.2 / U.3 NVMe SSD enclosures equipped with SFF-8639 female sockets. It comes with a dedicated 15Pin SATA power lead to simultaneously supply stable power and high-speed PCIe data signals to 2.5-inch NVMe drives, streamlining messy internal PC wiring.

Fully compliant with PCIe 4.0 specification, the cable retains complete x4 transmission bandwidth without signal loss, ideal for heavy-duty scenarios such as video editing, virtualization workstations and small storage servers. The integrated shielding structure effectively blocks electromagnetic interference generated by other internal hardware, ensuring steady read and write performance under long-hour continuous operation.

Every connector features corrosion-resistant gold-plated pins and locking clips to avoid accidental disconnection caused by chassis vibration. The 50-centimeter length eliminates excess slack, optimizes airflow inside compact towers and mini rack servers, and simplifies hardware installation and maintenance.

Compatible with all mainstream Intel and AMD motherboards, OCuLink storage controllers and standard SFF-8639 U.2/U.3 NVMe SSD modules. It is a practical upgrade accessory for PC DIY enthusiasts, media creators and enterprise server storage expansion.
