  • Data-only adapter — no video, audio or power-delivery support

NVME M-Key to USB 3.1 Type-E converter

This adapter converts an available NVME M-Key slot on a motherboard into a USB 3.1 front-panel header. It lets a case USB 3.1 port function even when the board lacks a native header. The ASM3242 chipset bridges PCI Express to USB 3.2 at 20Gbps.

20Gbps bandwidth with PCIe Gen3 x4 link

The ASM3242 host controller delivers up to 20Gbps over USB 3.2 Gen2 x2 while maintaining backward compatibility with legacy USB devices. Multiple INs optimise utilisation of the available bus bandwidth. The adapter does not support video, audio or power delivery functions.

Direct plug-in design for motherboard M-Key slot

The compact card inserts straight into an NVME NGFF M-Key PCIe 4.0 connector and connects to any standard USB 3.1 20-pin Type-E front-panel header. No extra brackets or cables are required for installation.

Questions about this item

Will the adapter work with my existing PCIe 3.0 motherboard slot?

Yes, the ASM3242 chipset bridges PCI Express Gen3 x4 to USB 3.2 20Gbps, so it operates at full speed on a PCIe 3.0 M-key slot.

How can I verify the adapter is delivering 20Gbps after installation?

Connect a USB 3.2 Gen2x2 device to the front-panel Type-E header and run a bandwidth test; sustained reads near 20Gbps confirm the link is trained at Gen2x2.

Does the package include the NVMe SSD or any mounting hardware?

The box contains only the converter card; you must supply your own NVMe M-key drive and the motherboard must provide a 20-pin USB 3.1 Type-E header.
