Flat green PCB adapter cable with M.2 M-key plug on one end, U.2 SFF-8639 connector on the other, 15-pin power lead, 50cm length

Vszerda

Vszerda PCIe 5.0 M.2 to U.2 Adapter Top Side Exit 50cm

SKU CH-JRP2-2G478

Connects a U.2 NVMe SSD to an M.2 2280 M key slot with PCIe 5.0 speeds up to 128 Gbps and includes a 15-pin power connector

  • Add a U.2 NVMe SSD through your M.2 2280 M-key slot
  • PCIe 5.0 delivers up to 128 Gbps theoretical bandwidth
  • Works with PCIe 4.0, 3.0, 2.0 and 1.0 drives
  • No drivers or software needed for installation
  • Requires a 15-pin SATA power connection to operate

PCIe 5.0 M.2 to U.2 adapter

This adapter connects a U.2 NVMe SSD to a motherboard M.2 2280 M key slot. It targets builders who want enterprise U.2 storage without a dedicated U.2 backplane. The 50 cm cable length allows flexible routing in full tower or server chassis. Buyers without a free M.2 M key slot cannot use this product.

Top side exit with 15 pin power

The male to male SFF 8639 connector exits from the top side of the M.2 plug, reducing strain in tight motherboard layouts. A separate 15 pin SATA power cable is required for the adapter to function. Premium materials and backward compatibility with PCIe 4.0, 3.0, 2.0 and 1.0 ensure durable daily use. Systems lacking a spare SATA power lead will need a splitter or extra PSU cable.

Passive thermals at 128 Gbps

No active cooling is present so the adapter relies on case airflow and the SSD's own heatsink. At the rated 128 Gbps theoretical rate the passive PCB adds negligible heat and zero noise. Power draw is limited to the drive plus the small adapter circuitry supplied from the SATA connector. High sustained workloads depend on the U.2 drive's thermal solution.
