M-Key to dual USB 3.1 adapter

This BUCIER adapter converts a motherboard NVME M-Key slot into two USB 3.1 Type-E headers. It enables front-panel USB 3.1 connectivity on chassis that lack a matching mainboard header. The compact plug-in design requires no extra cables or mounting hardware.

Sustained data throughput

The adapter bundles USB 3.1 traffic at up to 10 Gbit/s per port without active cooling. Continuous file transfers run at the interface limit rather than throttling under load. No power-delivery or video channels are present, so the link stays dedicated to data.

Interface practical limits

USB 3.1 Type-E headers cap at 10 Gbit/s and do not carry display or audio signals. The M-Key slot supplies only the PCIe lanes needed for the USB controller, so storage devices cannot share the same connector. Systems without an NVME M-Key cannot use this adapter.

Questions about this item

Does the BUCIER adapter draw extra power or generate heat when running all day?

The adapter converts an NVME M-Key slot into two USB 3.1 Type-E headers and requires no additional attachments, so it adds no active components that would increase power draw or heat.

What must my motherboard already have for this BUCIER adapter to work?

Your motherboard needs a free NVME M-Key slot; the adapter plugs directly into that slot and provides two USB 3.1 Type-E headers for front-panel ports.

Will the BUCIER adapter work with an older motherboard that only has USB 2.0 headers?

The adapter fits into an NVME M-Key slot and outputs USB 3.1 Type-E headers; it does not connect to legacy USB 2.0 headers, so the board must provide the M-Key slot for the adapter to function.
