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

This 50-centimeter OCuLink conversion cable connects OCuLink SFF-8611 ports on motherboards, PCIe expansion cards or RAID controllers to SFF-8639 female U. 2/U. 3 NVMe solid-state drives. Equipped with an independent 15Pin SATA power branch, it eliminates the need for extra separate power cords, simplifying internal chassis wiring layout. Complying with PCIe 4.0 industry standard, the cable supports full x4 high-speed data throughput without signal attenuation, perfectly matching enterprise-grade 2.5 -inch U. 2 NVMe SSDs for video editing, database storage and virtualization workstation workloads. The dense braided outer shielding effectively blocks electromagnetic crosstalk, maintaining consistent stable signals during long-hour continuous heavy read-write operations.

All terminals adopt thick gold-plated contacts and built-in safety locking latches to prevent accidental disconnection caused by equipment vibration. The short 50cm cord avoids redundant tangled cables, improves internal airflow and fits tight compact PC and mini server cases perfectly. Widely compatible with all mainstream Intel & AMD motherboards, OCuLink HBA/RAID adapters and all standard SFF-8639 U. 2/U. 3 NVMe drives. It is an essential storage upgrade accessory for DIY desktop builders, media production workstations and small enterprise server storage expansion projects.
