Green PCIe expansion card with four SFF-8643 ports and LED indicator

EN-Labs

EN-Labs Quad U.2 NVME SSD to PCIe 4.0/3.0 x16 Expansion Card

SKU CH-7KR6-WY75E

Connects four U.2 NVME SSDs via PCIe 4.0/3.0 x16 slot with 32Gbps bandwidth, requiring motherboard bifurcation support

  • Add four U.2 NVMe SSDs at once using a single PCIe 4.0/3.0 x16 slot
  • Delivers 32Gbps aggregate bandwidth across four SFF-8643 ports
  • Requires motherboard PCIe x16 bifurcation for full four-drive recognition
  • Includes full-profile and low-profile brackets for flexible case mounting
  • Built-in LED indicators show drive activity status at a glance

Four U.2 NVMe drives on one x16 slot

This expansion card adds four U.2 NVMe SSDs through a single PCIe 4.0 or 3.0 x16 connection. It targets builders who need high-density enterprise storage on a workstation or server board. The card carries four SFF-8643 MiniSAS ports wired for SFF-8639 U.2 drives only.

Requires motherboard PCIe x16 bifurcation

The board splits the x16 link into four x4 lanes so each SSD runs at full speed. Without bifurcation support only one drive will be detected. The upgrade is worth it when the platform exposes bifurcation in firmware and the user wants 32 Gbps aggregate bandwidth across four drives.

Check bifurcation and cable clearance

Verify the motherboard manual confirms PCIe x16 bifurcation before ordering. The package includes full-height and low-profile brackets but does not supply SFF-8643 to SFF-8639 cables. Ensure the case has room for the chosen bracket and cable routing.

Questions about this item

Does the card need a PCIe x16 slot with bifurcation to use all four U.2 drives?

Yes, the motherboard must support PCIEX16 bifurcation; without it only one U.2 NVME SSD will be recognised.

What cables are required to connect the drives to the SFF-8643 ports?

You need SFF-8643 to SFF-8639 cables for each U.2 NVME SSD; they are not included with the card.

Are the included brackets sufficient for both full-height and low-profile cases?

The card ships with both a full-profile and a low-profile PCI bracket so it can be mounted in either type of chassis.
