PCI Express 3.0 X16 U.2 SFF8639 2.5-in NVMe SSD Extend Card

      ▪ Support PCI-E Gen3, PCI-E Gen 2, PCI-E Gen 1

      ▪ Suggest to use PCI-E Gen3 slot for high performance.


PCI Express 3.0 X16 U.2 SFF8639 NVMe SSD Extend Card, supports a single U.2 NVME hard disk at most, and BIOS supports PCLs slot bifurcation. PCI Express 3.0 U.2 SFF8639 riser card is used as a bottleneck in the storage of servers and high-end desktop computers. By this adapter can be improved system speed ,and improve the efficiency of office and entertainment.

2-IN-1 Design

    - U.2 SFF-8639 to PCI-E or 2.5 inch SATA SSD to 7-Pin SATA Interface

    ▪ U.2 SFF-8639 to PCI-Express

      Turn 2.5 inch U.2 NVME SSD to PCI-E 3.0 X16 Gen3, support Intel SSD 750

    ▪ U.2 SFF-8639 to SATA

      Turn 2.5 inch SATA SSD to SATA III (SATA Cable included)

      PCI Express 3.0 X16 Lane Host adapter / Compatible with PCIe 3.0 and 2.0 motherboards


    ▪ Work with 2.5 inch U.2 NVME SSD, turn U.2 to PCI-E

      Attention: only PCIE channel, no need  SATA channel/cable

    ▪ Work with 2.5 inch SATA HDD\SSD, SATA to SATA 

      Attention: only SATA channel via SATA cable accessing PC, can not PCI-E channel


When install OS with NVMe SSD, please make sure Motherboard BIOS can be support PCIE SSD to boot up NVMe native driver for Windows 7 and Windows Server 2008 R2 is available from Microsoft Knowledge Base Mac Pro 2009, 2010 and 2012 models support PCIe-AHCI SSD.

    - The operating system must support the NVMe protocol before UEFI mode can support booting.

    - This card requires the motherboard to support split PCIe to support U.2 NVME hard drives, 

       and BIOS supports PCLs slot bifurcation
