Internal M.2 NVMe to PCIe Adapter Card MicroConnect MC-PCIE-NVME-SSDADAPT, PCIe 3.0, Host PCIe, Size 146×65.5×11.8 mm

MicroConnect MC-PCIE-NVME-SSDADAPT is an internal adapter card that enables installation of an M.2 NVMe SSD into a standard PCIe slot. Designed to work with PCIe 3.0 host interfaces and standard M.2 Key M drives, the adapter converts an NVMe M.2 connection to a PCIe x4 link for use in desktop or server systems. The card measures 146 × 65.5 × 11.8 mm and is compatible with common server operating systems.

Advantages

The adapter provides direct motherboard connection and supports PCIe 3.0 x4 lanes for high-bandwidth NVMe operation, offering theoretical transmit bandwidth consistent with PCIe Gen3 x4. Its compact form factor and standardized interface simplify installation of M.2 NVMe SSDs into systems lacking native M.2 slots. Intended for internal use, the card helps utilize modern NVMe storage in older or expanded workstation and server configurations.

Suitable for

• Adding an M.2 NVMe SSD to a desktop motherboard with available PCIe slot
• Upgrading server storage performance in systems that lack free M.2 sockets
• Testing or validating NVMe drives on workbench systems
• Expanding storage throughput for office applications and multimedia tasks

Key specifications

• Interface: PCI Express 3.0 host interface (PCIe x4)
• Supported SSD form factor: M.2 Key M NVMe SSDs (standard length support for common sizes)
• Maximum theoretical bandwidth: PCIe Gen3 x4-level throughput
• Compatibility: Desktop and server motherboards with compatible PCIe slot and OS support for NVMe devices
• Physical dimensions: 146 × 65.5 × 11.8 mm
• Intended use: Internal adapter card for NVMe storage

How to use

Install the M.2 NVMe SSD into the adapter’s M.2 slot following the manufacturer’s orientation and secure it with the provided mounting screw or standoff. Insert the adapter card into an available PCIe x4 (or higher) slot on the motherboard and fasten the card to the chassis. Power on the system and verify that the BIOS/UEFI and operating system recognize the NVMe drive; load any required drivers or enable NVMe support in firmware settings if necessary. Ensure the system firmware is up to date for proper NVMe initialization.

Usage recommendations

Use the adapter in a PCIe x4 or x16 slot to ensure full PCIe 3.0 x4 bandwidth. Maintain adequate airflow around the installed M.2 NVMe SSD to prevent thermal throttling; consider adding a heatsink if sustained high throughput is expected. Confirm OS and motherboard firmware compatibility before deployment, and handle the M.2 module with ESD precautions.
