AXT-LINK M.2 NVMe to PCIe 4.0 x4 Extension Cable

Product Overview

The AXT-LINK M.2 NVMe to PCIe 4.0 x4 Extension Cable is a high-speed PCIe Gen4 extension solution designed to connect an M.2 Key M NVMe interface to a PCIe x4 expansion interface.

This M.2 to PCIe x4 riser cable extends the connection between an M.2 NVMe slot on a motherboard and compatible PCIe expansion devices, providing greater flexibility for hardware installation, system integration, and internal component layout.

Supporting PCIe 4.0 x4 connectivity with a maximum specified aggregate link rate of up to 64 GT/s, this PCIe Gen4 extension cable is suitable for applications involving NVMe storage, PCIe network cards, USB expansion cards, capture cards, and other compatible PCIe x4 devices.

The cable features a flexible flat cable structure with electromagnetic interference (EMI) shielding to help reduce signal interference and maintain reliable high-speed data transmission.

Available in 90-degree, 180-degree, and 270-degree connector orientations, the M.2 NVMe to PCIe x4 extension cable provides installation flexibility for different motherboard layouts, chassis configurations, and hardware integration requirements.

AXT-LINK provides high-speed I/O flat cable solutions for bulk procurement, system integrators, and professional hardware applications.

Connector Orientation Options

The AXT-LINK M.2 to PCIe x4 extension cable is available in three connector orientation configurations to accommodate different installation layouts.

90-Degree Connector

Designed for right-angle installation where a horizontal or angled connection is required. Suitable for compact hardware layouts and systems with limited internal clearance.

180-Degree Connector

Designed for vertical or straight-through installation, providing an alternative connection orientation for motherboard and chassis integration.

270-Degree Connector

Designed for reverse-angle installation where the PCIe connection needs to face the opposite direction compared with the 90-degree configuration.

Selecting the appropriate connector orientation helps simplify cable routing and improve installation flexibility.

Applications

NVMe SSD and Storage Expansion

Connect compatible PCIe storage expansion hardware through an M.2 Key M NVMe interface. Suitable for storage system integration, NVMe expansion configurations, and compatible PCIe SSD applications.

PCIe Network Card Expansion

Extend an M.2 NVMe PCIe connection to compatible PCIe network adapters for networking hardware integration and system development.

USB Expansion Card Installation

Connect compatible PCIe-based USB controller expansion cards through an M.2 NVMe motherboard interface.

Video Capture Card Expansion

Provide an extended PCIe connection for compatible PCIe capture cards in workstation, recording, and video processing systems.

Custom PC and Embedded System Integration

The flexible flat cable and multiple connector orientations provide additional installation options for compact computers, industrial computing systems, workstation builds, and hardware development projects.

Compatibility and Installation Notes

1. The motherboard must provide an M.2 Key M slot supporting PCIe NVMe connectivity.

2. Confirm that the host M.2 slot supports the required PCIe lane configuration and operating mode.

3. The connected expansion device must use a compatible PCIe x4 electrical interface.

4. Actual operating speed depends on the motherboard, CPU, PCIe device, BIOS configuration, and negotiated PCIe generation.

5. PCIe 4.0 performance requires compatible PCIe Gen4 hardware throughout the connection.

6. Check the connector orientation and available installation space before ordering.

7. The cable should be routed without excessive pulling, twisting, or sharp bending.

Important: This product extends a PCIe connection. It does not convert an M.2 SATA-only interface into a PCIe NVMe interface.
