Small size, easy to plug and unplug, multiple PCI-E interfaces on the motherboard can test multiple SSDs at the same time. This converter card uses differential pair routing and supports PCI-E 3.0 4X signals. Supports M.2 of NVME protocols such for PM961, 960EVO, SM961, PM951, sm951, 600P, and T10. M.2 of the SATA protocol is not supported. M.2 hard drives with standard PCI-E or NVME on the SSD can be used. Support Solid State Disk Size: 2230, 2242,2260, 2280 Performance: Solving the reading and writing of NVMe M.2 interface SSD Input interface: M-Key M.2 (Not Support SATA protocol M.2 NGFF) Output Interface: PCI-e X16 Support Slot: PCI-e X4/X8/X16 (Not Support X1) NVMe SSD installation conditions: 1.PCI-E X4/X8/X16 are available; 2.Please install for Win10 system, for Win7 needs to install the driver, and the speed does not go up. 3.The motherboard does not support the NVME protocol cannot be used as a system disk and can only be used as a storage disk. About the motherboard: 1.for motherboard chipset: B250/B150/H170/Z170, as long as the motherboard with M.2 interface generally supports NVMe. Support part of the Z97, specifically query the website or BIOS the Nvme option. B85/Z87 needs to BIOS and be supported, B85 does not M.2 Interface, you can use this adapter card. 2.for AMD motherboard chipset: Support for the B350/X370/X399/A320 must be supported by Ryzen's CPU motherboard. Warm Tip: M.2 NGFF to PCI-E X16 converter card. Use this converter card to transmit the normal PCI-E X4 X8 X16 interface to M.2 NGFF interface. There are 4 fixed holes on the board, 22*32mm, 22*42 mm, 22*60 mm, 22*80 mm. size:95 X 40 X 3mm Material:Metal+pc colour:black Contents: 1 * M.2 to PCI-E3.0X16 adapter card 1 * silicone pads 1 * screwdriver Only the above content, other are not included.
