50cm 1.6ft PCIe 4.0 SFF-8654 Slim SAS 4i to SFF-8639 U.2 NVMe SSD Cable Adapter with 15Pin SATA Power Supply for Motherboard U2 Storage

This 50cm ( 1.6 ft) SFF-8654 4i to SFF-8639 U. 2 NVMe cable adapter supports PCIe 4.0 high-speed transmission and is fully backward compatible with PCIe 3.0. It connects Slimline SAS RAID adapters to U. 2 NVMe SSDs for high-performance storage expansion. Equipped with an integrated 15Pin SATA power connector, it directly provides stable power supply to U. 2 SSDs without separate power wiring. All connectors feature gold-plated contact pins to minimize signal attenuation and ensure steady data read-write performance. Double-layer shielding structure effectively isolates electromagnetic interference from GPU, power supply and other internal hardware to avoid data errors and transmission lag.

The soft bendable cable saves chassis space and simplifies internal routing without wire cracking. Plug-and-play, no extra drivers required. Ideal for DIY PC, workstation and server storage upgrade, NVMe RAID array building and motherboard U. 2 SSD expansion. Each cable passes strict factory signal and aging tests to guarantee reliable long-term high-load operation.
