PCIe 3.0 x16 to four U.2 NVMe adapter

This expansion card converts a single PCIe 3.0 x16 slot into four U.2 NVMe drive connections using SFF-8643 ports. It targets builders who need dense enterprise storage in a workstation or server chassis.

Requires motherboard PCIe bifurcation support

The card only functions when the host platform can split the x16 link into multiple lanes for each port. Without that capability the drives will not be detected, so the upgrade is only worthwhile on compatible chipsets.

Four U.2 drives with LED status per port

Each connector handles one NVMe SSD and the onboard indicator shows link activity. Bandwidth is shared across the x16 interface, so simultaneous heavy workloads on all four drives will saturate the upstream link.

Questions about this item

Does this card need a PCIe 3.0 x16 slot and motherboard bifurcation to use all four U.2 ports?

Yes, it installs in a PCIe 3.0 x16 slot and the motherboard must support PCIe split function so the x16 link can be divided among the four SFF-8643 connectors.

What is the most common mistake when installing this adapter?

Installing it on a board that lacks PCIe bifurcation; without split support only the first port will be active and the other three drives will not be detected.

Will the on-board LED indicator need any maintenance or replacement over time?

The LED is a simple surface-mount indicator powered from the slot; it has no user-serviceable parts and is not designed to be replaced separately.
