SMUGDESK PCIe 3.0 x4 to U.2 NVMe Adapter Card

SKU CH-W8PP-P51YK

Connects a U.2 NVMe SSD via PCIe 3.0 x4 at 32Gbps, fitting x4, x8 or x16 slots with plug-and-play setup

  • Up to 32Gbps throughput for fast NVMe data transfer
  • Fits PCIe 3.0 x4, x8 and x16 slots for broad compatibility
  • Dedicated U.2 port adds high-speed NVMe storage capacity
  • Stable signal design maintains reliable continuous operation
  • Plug-and-play setup works in servers and workstations

PCIe 3.0 x4 to U.2 NVMe Adapter

This adapter card connects a U.2 NVMe SSD to a PCIe 3.0 x4 slot. It delivers up to 32Gbps transfer speed for efficient data transmission. The card fits PCIe x4, x8 and x16 slots for broad compatibility. Simple plug-and-play installation suits servers and workstations.

Suits U.2 NVMe expansion; not for M.2 drives

This card suits users adding U.2 NVMe storage to a system with a free PCIe slot. It is not for builders who need to connect M.2 form factor SSDs. Buyers without an available PCIe x4, x8 or x16 slot should look elsewhere. The adapter requires a U.2 NVMe drive to function.

PCIe 3.0 x4 interface with 32Gbps speed

The PCIe 3.0 x4 interface provides up to 32Gbps bandwidth for the connected U.2 NVMe SSD. This specification determines whether the adapter matches the motherboard slot and drive performance needs. Verify the system has a compatible PCIe slot before purchase. The card supports PCIe x4, x8 and x16 slot configurations.

Questions about this item

Does my motherboard need a free PCIe 3.0 x4 slot to run this SMUGDESK adapter at 32Gbps?

Yes, the card is a PCIe 3.0 x4 device and will negotiate x4 speed in any x4, x8 or x16 slot, giving the full 32Gbps link to the U.2 NVMe drive.

Will a U.2 NVMe SSD on this adapter work if I keep an older PCIe 3.0 graphics card in the next slot?

The adapter uses its own x4 lane allocation, so the graphics card keeps its lanes and both devices operate independently at PCIe 3.0 speeds.

How can I confirm the U.2 NVMe drive is actually running at 32Gbps after I install the card?

Check the link width and speed in your OS device manager or BIOS — it should show PCIe 3.0 x4, which equals 32Gbps for the NVMe SSD.
