M.2 to U.2 NVMe adapter

This PCIe 5.0 adapter connects a U.2 NVMe SSD to an M.2 2280 M key slot on a motherboard. The cable measures 1.6ft and uses a left exit orientation. It supports theoretical speeds up to 128 Gbps and is backward compatible with PCIe 4.0, 3.0, 2.0 and 1.0 devices. No drivers are required.

Build integration and power

The adapter plugs straight into an available M.2 2280 M key interface and frees the U.2 drive to sit elsewhere in the chassis. A SATA power cable must be connected to the 15-pin power connector on the adapter for the drive to function. The 50cm length suits typical desktop or server layouts.

Upgrade path and limits

This adapter replaces a direct M.2 NVMe installation when a U.2 drive is preferred for capacity or endurance. The jump is worth it when the motherboard has a spare M.2 2280 M key slot and the builder can supply SATA power. It does not serve builds that lack an M.2 M key interface or that need more than four PCIe lanes.

Questions about this item

Does the 128 Gbps PCIe 5.0 link saturate before the U.2 NVMe SSD reaches its rated speed?

The adapter supports PCIe 5.0 x4 at up to 128 Gbps; sustained throughput will be limited by the specific U.2 NVMe SSD you install.

How much heat or noise does the adapter add when the U.2 drive runs continuously?

The passive cable assembly has no fan or active components, so it adds no audible noise and negligible heat beyond the drive itself.

Which power cable must already be present in the system for the adapter to work?

A standard 15-pin SATA power connector from the power supply is required to power the U.2 drive through the adapter.
