M.2 M-Key to OCuLink SFF-8612 adapter for NVME

This 15cm cable adds an SFF-8612 female port to a 2280 M-Key slot, enabling NVME U.2 SSDs or external graphics cards. It suits compact hosts, desktops and laptops that lack native OCuLink connectivity. Fixing holes secure the bracket in tight chassis. The 67-pin male plug seats directly into the motherboard socket.

Sustained PCIe 4.0 throughput at 64 Gbps

The link runs at PCIe 4.0 speeds using the NVMe protocol, maintaining 64 Gbps during extended transfers rather than only in short bursts. Backward compatibility with PCIe 3.0 preserves function on older platforms. High-speed shielding protects signal integrity across the full length under continuous load.

Black shielded cable with screw-mount brackets

The black OCuLink cable uses high-speed shielding to reject interference in dense builds. Both ends feature fixing holes so the SFF-8612 bracket and M.2 plug stay locked during vibration or cable routing. The short 15cm run minimises latency while keeping the external device close to the host.

Questions about this item

Does the 15cm M.2-to-Oculink cable generate noticeable heat or draw extra power during all-day NVMe SSD or eGPU use?

The cable is a passive 15 cm trace carrying PCIe 4.0 signals at up to 64 Gbps; it adds no active components, so heat and power draw are negligible.

What must my system already provide for the 67-pin M.2 M-key male connector to work with this adapter?

An available 2280 M-key slot wired for PCIe 3.0 or 4.0 with NVMe support; the host supplies all signalling and power.

Will the SFF-8612 female port work with my older PCIe 3.0 expansion chassis or U.2 backplane?

Yes, the Oculink interface is backward compatible with PCIe 3.0, so existing Gen 3 devices connect at their native speed.
