U.2 SFF-8639 To PCI-E X4 Expansion Card: You can use the PCE-E x4 expansion adapter to add 2.5 inch U.2 NVME SSD or 2.5 inch SATA SSD to your PC to improve system performance and expand the overall internal storage, support Windows 10, Windows 8, Windows 8.1, Windows Server 2012 R2, Linux, Fedora, SUSE and Ubuntu. 2. Dual Interface and Protocol: it is compatible with U.2 and SATA interfaces and protocols. It supplies power to the hard disk through the PCIE slot, and does not need to be connected to the power supply line. The U.2 SSD can be used directly without data cable,and the SATA data line needs to be connected when using the SATA SSD. 3. Warm Tips: 1. The motherboard that does not support NVME protocol cannot be used as system disk, but can only be used as storage disk. 2. This product is suitable for inserting into the PCIE X16 slot of the motherboard.Incorrectly inserting the PCI slot may damage the motherboard,adapter and SSD. 4. Compatible Model: Equipped with PCIE3.0 GEN3x4 interface,the transmission speed is up to 32GT/s,and the U.2 hard disk speed is played to a higher level. It is downward compatible with PCI-E Gen V2.0 and PCI-E GEN V1.0. 5. Heat Dissipation: This U.2 SFF-8639 To PCI-E X4 expansion card has a strong heat dissipation and stable operation for a long time . It can work under wide temperature, simplifying system construction, quick installation,precise PCB design,comprehensive suppression of EMI,complete signal.
