Dual M.2 NVMe adapter with Oculink x4

This Athena Power enclosure holds two M-key NVMe SSDs in 2242, 2260 or 2280 lengths behind a full-height PCIe bracket. It connects to the host through two Oculink 4i ports and uses mini 4-pin power connectors for each drive. The aluminium frame and stainless-steel tray include anti-vibration springs and a key-locked front bezel.

Adds two NVMe slots via Oculink

The card upgrades systems that lack enough native M.2 sockets or that need removable, front-accessible NVMe storage. It is worth the change when the platform provides PCIe 3.0 or 4.0 x4 lanes per drive through Oculink and the builder wants tool-free swap capability without opening the chassis. Builders whose boards have no Oculink headers cannot use this adapter.

Sustained thermal behaviour

The metal frame and open tray act as passive heatsinks for both SSDs during long write sessions. No fan is fitted, so airflow from the case must carry heat away from the exposed drives. The anti-vibration springs keep the SSDs firmly seated even when the system is moved while powered on.

Questions about this item

Will the full-height bracket fit in a standard 159 mm by 120 mm PCIe slot?

The card measures 159 mm long and 120 mm tall with an 18.5 mm thickness, matching a standard full-height PCIe bracket footprint.

How do I connect the two Oculink x4 cables and the Mini 4-pin power leads during installation?

Plug each Oculink 4i cable into the matching device port on the bracket, then attach both Mini 4-pin power connectors to supply the dual M.2 slots.

When should I replace the anti-vibration springs that hold the 2242, 2260 or 2280 SSDs in the tray?

Inspect the springs whenever you swap drives; replace them if they no longer keep the SSD firmly seated against the connector.
