PCIe 4.0 SlimSAS x4 to U.3 NVMe Cable, SFF-8654 38Pin 4i Host to SFF-8639 68Pin U.3 Drive Cable with SATA 15Pin Power, Internal Server Storage Wire, 75CM Length

This internal enterprise-grade PCIe 4.0 storage cable features a 38Pin SFF-8654 SlimSAS x4 male host connector, paired with a 68Pin SFF-8639 U.3 output port and integrated SATA 15Pin power lead, designed to connect U.3 NVMe SSDs to motherboards, RAID controllers and HBA cards equipped with SlimSAS 4i interfaces for internal high-speed storage expansion.

Fully compliant with PCIe Gen4 protocol, the cable delivers complete x4 bandwidth up to 16GT/s per lane, retaining native U.3 ultra-high read/write speeds without signal throttling or attenuation. The attached SATA power cable supplies stable auxiliary voltage to U.3 enterprise SSDs, eliminating messy extra power wiring inside compact 1U/2U rack chassis.

Measuring 75 centimeters long, this balanced-length harness balances installation flexibility and neat cable management, greatly optimizing heat dissipation inside data center servers, 4K video editing workstations and high-capacity NAS enclosures. Both ends adopt secure locking latch connectors to prevent accidental disconnection caused by long-term equipment vibration under heavy database, virtualization and rendering workloads.

Constructed with multi-layer braided shielding and low-loss 30AWG copper conductors with gold-plated precision pins, it effectively blocks electromagnetic interference and reduces signal loss to guarantee consistent 24/7 uninterrupted storage performance. This cable only supports U.3 NVMe SSDs and is not compatible with regular U.2 drives.

Wide hardware compatibility covers mainstream brands including Supermicro, ASUS, Gigabyte, Dell, LSI, Broadcom, as well as all standard SFF-8639 U.3 enterprise NVMe solid-state drives. Plug-and-play without driver installation required, ideal for server storage upgrades, high-density NVMe array deployment and professional high-speed computing projects.
