Adapter purpose and audience

The LetLinkSo LLS-CB-1MT1UT-01 connects a U.2 NVMe SSD to a motherboard M.2 2280 M-key slot. It suits desktop or server builders who need to add an enterprise-style drive without a dedicated U.2 port. It is not for users whose board lacks an M.2 M-key connector or who cannot supply SATA power.

Critical specification

The adapter runs at PCIe 5.0 x4 with a theoretical 128 Gbps ceiling and is backward compatible with PCIe 4.0, 3.0, 2.0 and 1.0 drives. A 15-pin SATA power cable must be attached for the U.2 device to operate.

Installation and common issues

The 50 cm straight cable with bottom-side exit routes cleanly in most chassis. Plug the M.2 end into the motherboard, attach the U.2 drive, then connect SATA power before booting. Forgetting the power lead is the typical reason the drive does not appear.

Questions about this item

What does 128 Gbps mean for my U.2 NVMe SSD in a real system?

It is the theoretical PCIe 5.0 x4 ceiling; actual throughput depends on your motherboard M.2 slot generation and the SSD itself

Which interface standard does the adapter use and what does it limit?

It connects an M.2 M key 2280 slot to an SFF-8639 U.2 drive over PCIe 5.0 x4 lanes, capping at 128 Gbps

What does the adapter need to fit and mount in my case?

A free M.2 2280 M key slot on the motherboard, a 50 cm cable run to the U.2 drive, and a 15-pin SATA power connection for the adapter
