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 links motherboards, OCuLink RAID/HBA expansion cards with SFF-8611 ports to U. 2/U. 3 NVMe SSD enclosures fitted with SFF-8639 female sockets. Equipped with an independent 15Pin SATA power lead, it simultaneously supplies stable power and high-speed PCIe data signals to 2.5 -inch NVMe drives, simplifying messy internal chassis wiring greatly. Fully compliant with PCIe 4.0 SFF-9402 standard, the cable retains complete x4 transmission bandwidth without signal attenuation, perfectly matching heavy workloads such as 4K/8K video editing, virtualization workstations and small enterprise storage servers. Multi-layer braided shielding effectively blocks electromagnetic interference from other internal hardware, maintaining consistent stable read/write performance under long-hour continuous heavy loads.

All terminals adopt corrosion-resistant thick gold-plated contacts 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.
