M-Key NVMe to USB 3.1 adapter

This adapter converts an available NVME M-Key slot on a motherboard into a USB 3.1 front-panel header. It enables a chassis USB 3.1 port to operate even when the mainboard lacks a native header. The compact card plugs directly into the M-Key slot and requires no extra cables or brackets. It suits builders adding front-panel USB 3.1 to systems without a matching motherboard connector.

Sustained 5 Gbit/s throughput via VL805

The onboard VL805 controller delivers up to 5 Gbit/s bandwidth over the USB 3.1 link during continuous transfers. It connects to a USB 3.0 20-pin socket on one side and a USB 3.1 20-pin front-panel header on the other. The copper construction maintains signal integrity across the conversion path. Performance scales with the host NVME drive and the attached USB device.

Requires motherboard NVME M-Key slot

This product only works when the motherboard provides an NVME M-Key slot that can be repurposed for the adapter. Boards without an M-Key NVME interface cannot use the converter. Buyers who need to add USB 3.1 headers without sacrificing an NVME slot should consider alternative solutions. The adapter does not create an NVME slot where none exists.

Questions about this item

Does the adapter add noticeable heat or power draw when the front-panel USB 3.1 port runs all day?

The compact VL805 converter plugs straight into the motherboard NVME M-Key slot and the USB 3.0 20-pin header, drawing only the bus power needed for 5 Gbit/s signalling.

What motherboard headers must I already have free for this adapter to work?

You need an open NVME NGFF M-Key slot and a spare USB 3.0 20-pin header; the board bridges those two connectors to create the front-panel USB 3.1 20-pin header.

Will this work alongside an older USB 2.0 front-panel cable I want to keep connected?

Yes, the adapter occupies the NVME M-Key slot and a USB 3.0 20-pin header only, leaving any existing USB 2.0 header free for the older cable.
