  • Connects U.2 NVMe SSDs via SFF-8654 Slimline
  • Supports PCIe 3.0 and 4.0 speeds
  • Includes 50 cm cable with adapter card
  • Designed for U.2 750 mainboard interface

Vszerda PCIe 3.0 4.0 Adapter Cable

This Vszerda adapter connects a mainboard SFF-8654 Slimline SAS port to a U.2 NVMe SSD using the SFF-8639 interface. It supports PCIe 3.0 and 4.0 signalling for compatible storage devices. The package includes one adapter card and one 50cm cable. It is designed for Windows 10 or later systems.

Replaces Direct SFF-8639 Mainboard Ports

Use this cable when your motherboard lacks a native U.2 connector but provides an SFF-8654 Slimline SAS header. The jump is worth it for adding high-speed NVMe storage without occupying a full PCIe expansion slot. It does not work with SAS or SATA disks, so buyers needing those protocols must look elsewhere.

Sustained PCIe 3.0 4.0 Link Behaviour

The adapter maintains a 4x PCIe 3.0 or 4.0 electrical link between the controller and the U.2 750 SSD under continuous load. Signal integrity relies on the 50cm cable length and the Hyper Kit storage controller design. Thermal performance depends on the host card and drive cooling, which are not included.
