75CM PCIe Gen4 X4 SFF-8654 38Pin SlimSAS to SFF-8639 68Pin U.2 NVMe Cable with SATA Auxiliary Power, High Speed Storage Converter Cable for Server HBA RAID Card

This 75-centimeter high-speed conversion cable complies fully with PCIe Gen4 X4 standard, converting SFF-8654 38Pin SlimSAS host port to SFF-8639 68Pin U.2 NVMe drive interface, widely used to connect enterprise U.2 NVMe SSDs with motherboards, HBA adapters and RAID controllers equipped with SlimSAS connectors.

It supports maximum 16GT/s per lane and total 64Gbps bidirectional bandwidth, maintaining native full read/write performance without signal attenuation even under continuous heavy storage workloads. An independent SATA 15Pin auxiliary power branch is integrated on the cable, delivering steady 12V/5V power to high-capacity U.2 SSDs and eliminating insufficient power issues causing drive disconnection or performance throttling.

The cable adopts impedance-controlled shielded differential pairs and gold-plated industrial-grade contacts, effectively resisting electromagnetic interference generated by server power supplies and cooling fans, ensuring long-term stable data transmission for data centers, rendering workstations and Chia plotting rigs. The 75cm moderate length reserves enough space for internal wiring layout in compact rack servers while avoiding redundant tangled cables that block airflow.

Backward compatible with PCIe 3.0/2.0 standards, it works with all mainstream U.2 NVMe SSD brands including Intel, Samsung, Western Digital and Micron, matching standard SlimSAS HBA cards and server mainboards. Latch-lock connectors offer tight plug fit to prevent accidental loosening during vibration of rack equipment. Plug-and-play design requires no extra drivers for fast deployment in storage expansion and server hardware upgrade projects.
