0.5M/1.6FT M.2 M-Key NVMe to U.2 SFF-8639 Extension Cable PCIe 4.0 x4 64Gbps with 15Pin SATA Power, for Mainboard M.2 Slot to 2.5" U.2 NVMe SSD Server Storage Docking

This PCIe 4.0 M.2 to U.2 conversion cable connects motherboard M.2 M-Key NVMe slots to SFF-8639 U.2 2.5-inch enterprise NVMe SSD drives and storage backplanes. Fully compliant with PCIe 4.0 x4 specification, it outputs full 64Gbps bandwidth without speed loss, backward compatible with PCIe 3.0 hardware.

Built with an extra 15Pin SATA power cord, it solves insufficient power supply issues of high-consumption U.2 SSDs, avoiding performance throttling or unexpected drive offline under heavy read-write loads. The cable adopts flexible thin wire structure, easy to arrange inside narrow server and desktop chassis without blocking cooling vents.

Strict differential impedance design plus multi-layer anti-interference shielding effectively suppress signal noise from nearby GPU and power modules, maintaining stable long-term connection during mass data backup, video editing and RAID array operation. All contact pins are gold-plated to resist oxidation and reduce contact failure risk after years of use.

It is widely used for mainboard without native U.2 port storage expansion, small workstation enterprise high-speed storage upgrade, server storage hardware reconstruction and IT hardware enthusiast modification, a cost-effective high-performance storage extension cable for data centers and creative creators.
