PCIe 4.0 OCuLink SFF-8611 to SFF-8639 U.2 NVMe SSD Cable with SATA 15Pin Power, Internal Motherboard Storage Expansion Wire, 0.5M / 1.64FT Length

This internal PCIe 4.0 OCuLink storage cable features a standard SFF-8611 4i OCuLink male host connector, paired with SFF-8639 U.2 output port and an attached SATA 15-pin power harness, built to connect U.2 NVMe SSDs to motherboards, RAID controllers and HBA cards with OCuLink interfaces for internal storage expansion.

Fully compliant with PCIe Gen4 protocol, the cable supports complete x4 bandwidth up to 16GT/s per lane, retaining native NVMe ultra-high read/write speeds without throttling or signal attenuation. The built-in SATA power connector delivers steady voltage to power-hungry SFF-8639 U.2 solid-state drives, eliminating messy extra power wiring inside compact PC and server chassis.

Measuring 0.5 meters (1.64 feet) long, this balanced-length harness balances installation flexibility and tidy cable management, optimizing heat dissipation inside rack servers, DIY workstations and high-capacity NAS enclosures. Both ends adopt secure locking latch design to avoid accidental disconnection caused by chassis vibration during long-term heavy workloads.

Constructed with multi-layer braided shielding and high-conductivity gold-plated contact pins, it effectively blocks electromagnetic interference and reduces signal loss to guarantee consistent data performance for 24/7 enterprise operation. Widely compatible with mainstream hardware brands including Supermicro, ASUS, Gigabyte, LSI, Broadcom, as well as all standard SFF-8639 U.2 NVMe SSDs like Intel P3600/P3700 series. Plug-and-play without driver installation required, ideal for server storage upgrades, 4K video editing workstations and high-density NVMe array deployment.
