M.2 to U.2 NVMe adapter

This PCIe 4.0 adapter connects a U.2 NVMe SSD to an M.2 2280 M key slot on a motherboard or add-in card. It targets builders who want enterprise or high-capacity U.2 drives in a desktop or workstation without a native U.2 port. The 50cm braided cable uses a left-exit M.2 connector for cleaner routing in tight chassis.

Check motherboard slot and power

Verify the board has a free M.2 2280 M key slot wired for PCIe 4.0 or earlier generations. The adapter draws drive power from a standard 15-pin SATA power connector, so a spare lead from the power supply is required. No drivers or software are needed for operation.

Upgrades from M.2-only storage

The adapter lets you move from consumer M.2 drives to U.2 SSDs that often offer higher endurance and sustained write performance. The jump is worthwhile when workloads demand the 64 Gbps PCIe 4.0 ceiling and the physical U.2 form factor fits the build. It does not suit systems lacking an M.2 M key slot or a SATA power lead.

Questions about this item

What does the box contain and is a separate power cable needed?

The package includes one PCIe 4.0 M.2 to U.2 adapter with a 50cm braided cable. A SATA power cable must be connected to the adapter for it to function.

Which PCIe generation should I select for my U.2 NVMe SSD?

The adapter runs at PCIe 4.0 speeds up to 64 Gbps and remains compatible with PCIe 3.0, 2.0 and 1.0 drives, so choose the version that matches your SSD and motherboard capabilities.

What does the 64 Gbps headline figure mean once the adapter is installed in my system?

It is the theoretical maximum bandwidth of the PCIe 4.0 x4 link between the M.2 2280 slot and the U.2 NVMe SSD; actual throughput depends on the specific drive and motherboard implementation.
