PCI-E 4X to U.2 Adapter Kit

This kit adapts a PCI Express x4 slot to a U.2 NVMe SSD using SFF-8639 and SFF-8654 Slimline SAS connectors. It targets builders adding high-capacity enterprise storage to a standard motherboard. The card operates on a PCIe 3.0 x4 electrical link. A standard bracket is included for secure case mounting.

Fits a PCIe x4 slot and U.2 drive

Installation requires an available PCI Express x4 slot and a compatible U.2 NVMe SSD. The adapter bridges the motherboard slot to the drive without an extra power cable. It frees M.2 positions for other devices. The card does not support SAS or Slimline SAS hard drives.

Sustained PCIe 3.0 x4 throughput

Under continuous load the link runs at PCIe 3.0 x4 speeds, matching the rated electrical interface. Performance scales with the attached NVMe SSD rather than the adapter itself. Thermal behaviour depends on case airflow around the bracket-mounted card. The adapter adds no active cooling or latency beyond the passive trace length.

Questions about this item

What PCIe generation and lane width does the adapter use?

The adapter connects through a PCIe 3.0 x4 slot on the motherboard.

How much heat or noise does the adapter add when running all day?

The adapter is a passive board with no fan or active components, so it adds no audible noise and negligible heat.

What drive and slot must already be present for this kit to work?

You need a PCIe-based U.2 NVMe SSD and an available PCIe 3.0 x4 slot on the mainboard.
