HDMini SAS SFF-8643 to SFF-8639 with Mounting Ears High-Speed Cable | 12Gbps SAS 3.0 + 15P SATA Power
The maxmoge MC4339M is a high-performance internal server combo cable designed for high-vibration and industrial server environments. It connects RAID/HBA controller cards (SFF-8643) to U.2 (SFF-8639) interface NVMe/SAS/SATA drives, featuring an integrated SATA 15P power connector for stable drive power supply. The SFF-8639 end is equipped with M3 screw-mountable ears for secure fixation, effectively preventing connection loosening in high-vibration working conditions. Supporting SAS 3.0 (12Gbps), PCIe 4.0 (16GT/s), and SATA 6Gbps, it is ideal for industrial servers, edge computing devices, high-vibration rackmount servers, and workstations.
⚠️ Note: This is an internal cable. Ensure your controller uses an SFF-8643 interface, your drive uses an SFF8639 (U.2) interface, and connect the SATA power to the power source. The mounting ears require M3 screws for fixation (screws not included).
