SMUGDESK PCIe 3.0 x4 to U.2 NVMe Adapter Card 32Gbps/64Gbps

SKU CH-RKAN-7R26V

PCIe 3.0 x4 adapter adds a U.2 NVMe SSD slot at up to 32Gbps, fitting X4, X8 or X16 motherboard slots

  • Up to 32Gbps throughput via PCIe 3.0 x4 interface
  • Backward compatible for high-speed data transfer with existing systems
  • Fits PCIe X4, X8 and X16 slots for wide motherboard compatibility
  • Dedicated U.2 NVMe port expands high-performance storage capacity
  • Stable signal design ensures reliable long-term running performance

PCIe 3.0 x4 U.2 NVMe adapter for storage expansion

This PCIe 3.0 x4 adapter card adds a U.2 NVMe SSD connection to servers and workstations. It fits PCIe X4, X8 and X16 slots for broad motherboard compatibility. The card supports up to 32Gbps transfer speed on PCIe 3.0 links. Installation is plug-and-play with no extra drivers required.

Sustained 32Gbps throughput on PCIe 3.0 links

The adapter maintains up to 32Gbps bandwidth during extended transfers rather than only in short bursts. Stable signal design keeps data integrity consistent across long workloads. Backward compatibility lets the card negotiate lower speeds when the slot or drive requires it. No thermal throttling or controller overhead limits are described in the specifications.

Passive cooling with no added power draw

The card operates without a fan, relying on chassis airflow for cooling. It draws power only from the PCIe slot and needs no external connector. Silent operation suits noise-sensitive server racks and workstations. Builders who need active cooling or onboard temperature monitoring cannot meet that need with this adapter.

Questions about this item

How much heat or noise does the PCIe 3.0 x4 to U.2 NVMe adapter add when running all day?

The adapter itself is a passive card with no fan, so it adds no audible noise. Power draw is limited to the PCIe slot specification, and the U.2 NVMe SSD typically idles at low wattage with higher draw only under sustained heavy load.

What must I already own for this U.2 NVMe adapter to work?

You need a motherboard with a free PCIe x4, x8 or x16 slot, a U.2 NVMe SSD, and a U.2 cable to connect the drive to the card.

Will the card work alongside an older PCIe 2.0 graphics card in the same system?

Yes. The adapter is backward compatible and will negotiate the highest common PCIe link width and speed supported by the slot and the U.2 NVMe SSD.
