Extension Cable for U.2 NVMe SSDs
This 50cm cable extends a U.2 SFF-8639 connection between a host and an NVMe PCIe SSD. It features a 68-pin male connector on one end and a matching female connector on the other. The assembly is designed for internal routing inside a chassis or drive bay. It suits builders who need to relocate a U.2 drive away from the backplane or motherboard header.
Plug-and-Play Installation
The cable requires no drivers or configuration; simply connect the male end to the host port and the female end to the drive. Ensure the 68-pin connectors are fully seated to avoid intermittent link training. A common issue is excessive bending near the connector housing, which can stress the internal wiring over time. Route the 50cm length with gentle curves rather than sharp angles to maintain signal integrity.
PCIe 2.0 and 3.0 Link Speeds
The cable supports data transfer rates up to 2 GB/s over PCI Express 2.0 and up to 4 GB/s over PCI Express 3.0. It comfortably handles typical enterprise NVMe workloads within those link generations. Bandwidth will saturate at the 4 GB/s ceiling, so drives capable of PCIe 4.0 or 5.0 speeds will operate at reduced throughput. Builders needing higher link rates should consider a different interconnect solution.

Questions about this item
How can I confirm the cable is delivering the full PCIe 3.0 speed of 4 GB/s after connecting my NVME drive?
Check the host BIOS or operating system link-speed report; it should show PCI Express revision 3.0 and a negotiated transfer rate of 4 GB/s for the attached NVME SSD.
What does the package contain and is any additional hardware required to complete the U.2 link?
The package includes one 50 cm U.2 SFF-8639 68-pin male-to-female extension cable; no extra connectors or adapters are needed if both the host and drive already have matching U.2 ports.
Should I choose a different length or pin count for my 68-pin U.2 NVME setup?
This model is fixed at 50 cm and 68 pins, matching the SFF-8639 specification; select it when that exact length and pin-out are required for your NVME installation.
