HDMini SAS SFF-8643 to SFF-8639 + 15P SATA Power Cable | 12Gbps SAS 3.0
The maxmoge MC4339 is a high-performance internal server data + power integrated cable designed to connect SAS RAID/HBA controller cards with SFF-8643 interface to U.2/U.3 (SFF-8639) interface NVMe/SAS SSDs. It fully complies with the SAS 3.0 (Rev 5a) specification, supporting 12Gbps high-speed data transmission, and integrates a 15-pin SATA power interface to directly supply power to the SSD, eliminating the need for additional power cables.
Typical applications include 1U/2U rackmount server internal storage expansion, workstation U.2/U.3 SSD connections, data center high-density storage systems, and industrial server storage upgrades.
⚠️ Note: This cable integrates data transmission and power supply functions. The SFF-8643 end is connected to the RAID/HBA controller card, and the SFF-8639 + 15P SATA end is connected to the U.2/U.3 SSD. Please confirm that your device interface matches before use.
