SKU CH-9AGR-3K344

Adapts a 2.5-inch U.2 NVMe SSD to a PCI Express x4 slot using the SFF-8639 interface

  • Connect 2.5 NVMe drives via PCI Express x4
  • SFF-8639 interface enables direct NVMe communication
  • Includes 7-pin SATA cable for power delivery
  • CE and FCC certified for regulatory compliance
  • Mounting hardware and screwdriver supplied for installation

U.2 NVMe adapter for 2.5 inch drives

This adapter lets you install a 2.5 inch U.2 NVMe SSD into a desktop PCI Express slot. It is aimed at builders and technicians who need to add enterprise or high-capacity U.2 storage to a system that lacks a native U.2 connector.

PCI Express x4 host interface

The card connects through a PCI Express x4 slot and presents a SFF-8639 connector for the drive. That x4 link is the single specification that decides whether the adapter can deliver full NVMe performance in your platform.

Mounts in a standard expansion slot

The package includes two bracket screws, four SSD screws, a screwdriver and a 7-pin SATA cable for power. It fits any chassis with a free full-height slot and requires no additional drivers beyond the operating system NVMe stack.

Questions about this item

How does the PCI Express x4 connection affect real-world throughput with a U.2 NVMe drive?

The x4 lane width lets the drive run at its full PCIe generation speed without bottlenecking the NVMe protocol.

What does the SFF-8639 connector actually carry, and does the included SATA cable play any role?

The SFF-8639 port carries four PCIe lanes plus a SATA interface; the 7-pin SATA cable is only needed if you attach a SATA-based U.2 drive.

Will this card fit in a low-profile chassis, and how is the 2.5" drive secured?

Two bracket screws are supplied for standard-height slots; four SSD screws and a screwdriver mount the 2.5" drive directly to the adapter.
