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 Motherboard 2.5" NVMe Drives

This 50-centimeter OCuLink conversion cable connects motherboards, OCuLink RAID/HBA expansion cards equipped with SFF-8611 ports to U.2/U.3 NVMe SSD enclosures with SFF-8639 female sockets. It is built with a dedicated 15Pin SATA power branch, delivering stable power and high-speed PCIe data signal to 2.5-inch NVMe drives simultaneously, greatly simplifying messy internal PC wiring layout.

Fully compliant with PCIe 4.0 industry standard, the cable maintains complete x4 transmission bandwidth without signal attenuation, ideal for heavy workloads including 4K/8K video editing, virtualization workstations and small enterprise storage servers. Multi-layer braided shielding effectively blocks electromagnetic interference generated by other internal hardware, sustaining steady read/write performance under long-hour continuous heavy loads.

All terminals adopt corrosion-resistant thick gold-plated pins and built-in safety locking latches to avoid accidental disconnection caused by chassis vibration. The short 50cm cord removes redundant cable slack, optimizes internal airflow and fits tight compact tower PCs and mini rack servers perfectly.

Compatible with all mainstream Intel & AMD motherboards, OCuLink storage controllers and standard SFF-8639 U.2/U.3 NVMe SSD modules. It is an essential storage upgrade accessory for PC DIY builders, media creators, data center technicians and enterprise server storage expansion projects.
