Small green circuit board with M.2 M-key slot and Oculink SFF-8612 connector

Manw

Manw M.2 M-Key to Oculink SFF-8612 Adapter (F4C) data adapter

SKU CH-6QT6-9QA6S

Converts an M.2 M-Key NVMe slot to an Oculink SFF-8612 port with PCIe 4.0 x4 bandwidth up to 64 Gbps, supports 2230, 2242, 2260 and 2280 drive lengths.

  • PCIe 4.0 x4 delivers up to 64 Gbps throughput
  • Amphenol SFF-8612 connector ensures stable full-speed transmission
  • UL-certified PCB with 15 µ" gold fingers resists oxidation
  • Supports M.2 2230, 2242, 2260 and 2280 NVMe drives
  • Adapter can be cut to fit space-constrained builds

M.2 M-Key to Oculink SFF-8612 Adapter

This adapter converts an M.2 M-Key NVMe slot into an Oculink SFF-8612 port for PCIe 4.0 x4 connectivity. It supports M.2 2230, 2242, 2260 and 2280 form factors and can be trimmed to fit specific space constraints. Builders use it to relocate high-speed storage or add external NVMe devices without occupying a motherboard slot.

Thermals noise and power

The passive PCB design adds no active cooling or moving parts so it produces zero noise and draws no additional power beyond the attached NVMe device. Gold-plated 15µ contacts and UL-certified PCB material maintain signal integrity at PCIe 4.0 speeds up to 64 Gbps. Stable transmission reduces the risk of link errors that can cause system instability.

Build integration

The Amphenol Oculink SFF-8612 connector enables a secure cable link to a backplane, riser or external enclosure. By moving the drive off the motherboard the adapter frees the M.2 slot for other devices or improves airflow around dense components. It requires a compatible Oculink cable and a host system with PCIe 4.0 support to deliver full bandwidth.

Questions about this item

How do I install the Manw M.2 M-Key to Oculink SFF-8612 adapter and which M.2 lengths does it support?

Insert the M.2 NVMe SSD into the M-key slot — it accepts 2230, 2242, 2260 and 2280 lengths — then secure it with the screw. Connect an Oculink SFF-8612 cable to the Amphenol connector. The PCB can be cut if clearance is tight, but do this before mounting any drive.

What maintenance or replacement will the adapter need over time?

The gold fingers are plated to 15µ" to resist oxidation and rust, which reduces connection-related blue screens. No routine maintenance is required; just keep the contacts clean. Replace the adapter only if the PCB is damaged or the Oculink connector fails.

What bandwidth limit appears first under sustained PCIe 4.0 x4 loads?

The adapter is rated for PCIe 4.0 x4 with a maximum throughput of 64G/bps. That ceiling is the first hard limit you will hit during sustained transfers, assuming the host, cable and NVMe drive all support gen4 speeds.
