DELOCK PCIe 4.0 ohut SAS-kaapeli SFF-8654 8i – 2× U.2 SFF-8639 -liitäntä virtaliitännällä 0,5 m

DELOCK PCIe 4.0 slim SAS cable SFF-8654 8i to 2× U.2 SFF-8639 sockets with power connector 0.5 m is an internal connection cable designed to link a single SFF-8654 8i host port to two U.2 (SFF-8639) drives. The 0.5 meter cable supports PCIe 4.0 signalling for NVMe/U.2 SSDs and integrates a power connector to feed the connected drives, enabling a compact and reliable internal routing solution for servers and workstations.

Advantages

The cable supports PCIe 4.0 data rates, allowing high-speed NVMe communication between host and U.2 drives while maintaining signal integrity in a slim form factor. Its dual-socket design enables two U.2 drives to share a single SFF-8654 host connection, and the built-in power connector removes the need for separate power cabling from the power supply. Short 0.5 m length reduces clutter and is suitable for dense internal layouts where space and airflow are considerations.

Suitable for

• Connecting two U.2 NVMe SSDs to a single SFF-8654 host port in servers
• Internal workstation configurations requiring compact, high-speed storage links
• Environments where short cable runs and tidy cable management are needed
• High-performance storage setups using PCIe 4.0-capable controllers and drives

Key specifications

• Cable type: slim SAS with SFF-8654 8i to two SFF-8639 (U.2) sockets
• Length: 0.5 m
• Interface support: PCIe 4.0 signalling suitable for NVMe/U.2 SSDs
• Includes integrated power connector for drive power delivery
• Intended use: internal server and workstation installations

How to use

Install the cable inside the chassis by connecting the SFF-8654 8i plug to the host controller or backplane port. Route the cable to the drive bays and attach each SFF-8639 socket to the corresponding U.2 SSD. Connect the integrated power connector to the appropriate internal power header or cable to supply drive power. Ensure connectors are fully seated and that the cable is routed to avoid obstructing fans or other components.

Recommendations

Use the cable only for internal connections in compatible systems with PCIe 4.0-capable controllers and U.2 NVMe drives. Verify that the host port supports bifurcation or the required lane mapping for two drives as needed by your controller. Maintain proper airflow and avoid tight bends near the connector ends to preserve signal integrity.
