PCIe 4.0 SlimSAS SFF-8654 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 SlimSAS storage cable features a SFF-8654 4i SlimSAS male host connector, paired with a SFF-8639 U.2 output port and an attached SATA 15-pin power lead, specially designed to connect U.2 NVMe SSDs to motherboards, RAID controllers and HBA cards with SlimSAS interfaces for internal storage expansion.

Fully compliant with PCIe 4.0 protocol, the cable supports full x4 bandwidth up to 16GT/s per lane, maintaining native NVMe high read/write speeds without throttling or signal attenuation. The integrated SATA power connector directly supplies steady voltage to SFF-8639 U.2 solid-state drives, eliminating messy extra power cable arrangements inside compact chassis.

Measuring 0.5 meters (1.64 feet) long, this moderate-length harness balances installation flexibility and tidy cable management, optimizing heat dissipation inside rack servers, DIY workstations and high-capacity NAS enclosures. Each connector adopts a secure locking latch design to prevent accidental disconnection under long-time vibration and heavy workloads.

Constructed with shielded braided wiring and high-conductivity gold-plated contact pins, it effectively blocks electromagnetic interference to guarantee consistent data performance during 24/7 continuous 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 such as Intel P3600/P3700 series. Plug-and-play with no driver installation required, ideal for server storage upgrades, high-speed media editing workstations and data center NVMe array deployment.
