M.2 NGFF PCIe M Key Adapter

This adapter converts an M.2 NGFF M key slot into a PCIe 4x female socket so a standard PCIe card can be installed in a desktop or laptop. It supports 2260 and 2280 module lengths and provides data transfer up to 4.0GB/s through a socket 3 M key interface. The board can be broken off to match the required length and includes a floppy 4 pin to Molex power cable plus mounting hardware.

Suits builds needing a PCIe slot from an M key

Builders who want to add a PCIe expansion card using an available M.2 M key slot will find this adapter fits the purpose. It is not for systems that only offer an M.2 B key or B+M key socket because the connector requires a dedicated M key interface. Buyers needing multiple PCIe lanes beyond 4x or a different keying should look at other solutions.

Requires an M.2 Socket 3 M Key slot

The adapter only works with an M.2 Socket 3 (M Key) NGFF PCIe-based slot and will not function in sockets with other keying. Confirm the motherboard or laptop provides this exact socket type before purchase.

Questions about this item

What must my motherboard already have for this Corn Electronics adapter to fit?

An M.2 NGFF M‑key slot wired for PCIe, plus a free PCIe x4 connector with enough clearance for the adapter card.

Will my existing PCIe x1 or x4 expansion card work when plugged into this adapter?

Yes, the adapter presents a standard PCIe x4 female socket, so any PCIe x1 or x4 card will operate at up to 4.0 GB/s.

How can I confirm the adapter is running at the stated 4.0 GB/s after installation?

The OS will recognise the attached PCIe card without drivers; verify the link speed in device manager or lspci to see a 4.0 GT/s per lane connection.
