Features: brand new and high quality for M.2 PCIE NVMe adapter card converts for M.2 (for M for Key) interface to PCIe 3.0 x4 interface.(for M.2 SATA protocol SSD is not supported). With multi-layer for protection board, overcurrent for protection，overvoltage for protection, short circuit for protection Super-thick and gold-plated SSD contact surface increases the heat conduction medium to dissipate heat efficiently and is more durable. Large-capacity solid capacitors: constant voltage, constant current, anti-surge. Support high-speed and large-capacity storage interface, the speed is determined by the host end of the computer motherboard, and not affect Support 2230/2242/2260/2280/22110mm M-Key SSD. Specifications: Item name: for M.2 to PCI-E Adapter Card Power supply: PCI-E power supply Size: Approx 135x54mm/5.3x2.1in Plug Type: Full-height Short Baffle: approx 120mm/4.72in / Half-height Short Baffle:approx 80mm/3.15in (Optional) Material; PCB+Metal Package Includes: 1 piece for M.2 to PCI-E Adapter Card (Does Not Contain Hard Disk) 1 Piece Metal Baffle note: If your motherboard chipset is below 9 series, it is not recommended to use NVMe protocol PCIe x4 and NVMe protocol PCIe x2 for M.2 solid state drive! Some older motherboards have only one PCIE 3.0 graphics card slot, and other redundant graphics card slots are PCIE 2.0. Inserting the PCIe 2.0 slot will slow down the operation of the solid state drive! The original win 10 installation disk must be used to install the system. Win7 system and PE system do not support Nve protocol solid state drives.
