16x PCI Express Riser for 4 U.2 NVMe SSDs or 4 PCIe 4X ports with SFF-8643 plugs. Bifurcation mode Only.

PCI Express x16 Bifurcation Riser Card for PCIe 3.0 to SFF-8643 connector. It connects to NVMe SSD or PCIe connectors via SFF-8643 connector and Cables. This card requires SPLIT PCIE on the motherboard to support Four U.2 NVMe hard drives, and BIOS supports PCIe Slot bifurcation.

Comes with a full-profile bracket (preinstalled), and also includes a low-profile bracket for a small form-factor computer.
Computer with PCI Express Slot (x16) support PCIe bifurcation mode.
Please kindly verify with your mainboard manufacturer (such as Intel, Supermicro, Tyan, ASRock, Gigabyte...) to make sure the motherboard BIOS support Bifurcation for the PCI Express you are using.
