M.2 To U.2 Expansion Card Adapter PCIe M2 Converter SFF-8639 SSD Expansion Card Dual Interface Compatible With NVMe/SATA SSD Description: Brand: JEYI/ Jiayi. Name: M.2 to U.2 expansion card. Model: U2PCB. Service: Three-year warranty, factory direct repair for life. Advantages: Integration of Jiayi high-speed signal enhancement technology and full-speed transmission; Accurate and solid structural design; Support NVME SSD and SATA NGFF SSD; Two 5A high power DC TO DC power supply modules; Long-term operation is stable and can work under wide temperature; PCIE3.0 X16 GEN3 design ensures full speed from the bottom of technology. Specifications: PCI-E3.0 X16 GEN3 SFF-8639 U.2 High Speed Transmission Protocol. Two groups of 5AX2 high-power modules are integrated with high-power inductors. Two sets of DC modules guarantee redundancy and the design concept of aircraft dual engines. High elasticity connector, strong connection, durability, stability and earthquake resistance, and hardware protection. Two disks can work at the same time, but our U2 X16 expansion card must be selected. Note: NGFF of SAT A protocol must be connected to the motherboard with SATA 7Pin data cable before U2X16 can be operated. B: m.2 NGFF of SATA protocol; Usually there are two gaps (supported by this product). M key: m.2 NVME of pcie protocol; Usually a gap (supported by this product). M.2 disks can be used only if they have NVME or SATA label on them. Material: PCB Support capacity: 2T. Transmission speed: U2 SFF-8639. Package: 1* adapter plate, 2* moving stud, 1* screwdriver. Package Included: 1* adapter plate. 2* Move the stud. 1* screwdriver. or
