QNAP QM2 CARD interface cards/adapter Internal PCIe M.2 PCIe Low-profile

The QNAP QM2 CARD internal PCIe expansion card provides an M.2 host interface with PCIe output in a compact low-profile form factor. Designed for installation inside desktop PCs and small form factor systems, the card expands internal connectivity and enables the use of M.2 devices with a direct PCIe connection. Its silver finish and small dimensions (152.7 mm × 68.9 mm × 18.9 mm) make it suitable for systems with limited space while maintaining compatibility with standard PCIe slots.

Advantages

The QM2 CARD offers a straightforward way to add an M.2 host interface to a PC using an internal PCIe connection, improving flexibility for storage and expansion. Its low-profile design allows installation in compact chassis where full-height adapters would not fit. The card’s internal configuration reduces external cabling and preserves a clean build, while the silver housing provides a neutral appearance that integrates with most system interiors.

Suitable for

• Adding M.2 device connectivity to desktop or compact PCs
• Upgrading system I/O without using external enclosures
• Small form factor builds where low-profile expansion cards are required
• Systems requiring direct PCIe output from an internal M.2 host interface

How to use

Install the QM2 CARD into an available internal PCIe slot following the computer and motherboard manufacturer's instructions for power-off installation. Secure the low-profile bracket in the chassis and ensure the card is firmly seated in the slot. Connect an M.2 device to the card’s M.2 host interface according to the device orientation and mounting requirements. After installation, power on the system and verify device recognition in the operating system or BIOS/UEFI. Apply any required drivers or firmware updates provided by the system or device manufacturers.

Recommendations

Before installation, confirm chassis clearance for the card's dimensions and verify motherboard PCIe lane availability. Use compatible M.2 devices that match the card's supported interface specifications and follow anti-static handling precautions. For stable operation, keep system firmware and drivers up to date and monitor thermal conditions when installing high-performance M.2 modules in compact enclosures.
