Specification: Material: PCB Color: Shown as picture Support M.2 Card Size: 22*30mm, 22*42mm, 22*60mm, 22*80, 20*110 Port: PCI-E 1X, PCI-E 4X Support System: Compatible with WIN7/WIN8/WIN8.1/WIN10 system Package Weight: Approx.123.5g/4.4oz Power supply mode: PCI-E power supply, support system startup function. Interface: Provide 2*M.2 slots, M NGFF interface, B NGFF interface. Package List: 1 * Adapter Card 1 * Back Plate 1 * SATA Cable 1 * Screw Pack Note: 1. Please allow 1-3cm error due to manual measurement. Thanks for your understanding. 2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. B-Key Interface and M-Key Interface: B-Key interface can insert with SSD of M.2 NGFF SATA protocol, the insert SATA line to connect mainboard.M-Key interface can insert with SSD of M.2 NVME PCI-E protocol. PCI-E transmission data is able to connect mainboard without accessing SATA line. Super-Thick Gold-Plated: SSD NGFF adapter card uses the SSD contact surface to be super-thick gold-plated, and the heat dissipation is enhanced after adding the thermal conductive medium; it has a high-speed mass storage interface of SATA3/6Gbps, and the speed is mainly controlled by the computer motherboard. Use A Standard SATA-IO M.2 SATA SSD: The riser card allows users to use a standard SATA-IO M.2 SATA SSD to switch to a desktop computer to become a SATA hard drive. You can connect M.2 (NGFF) SSD as a notebook hard disk card 11.M.2 (NGFF) SSD, and connect to the host for data transmission through its NGFF slot transmission. Useing 12V+3.3V Dual Voltage: The adapter card uses 12V+3.3V dual voltage, which is more stable than single voltage, effectively reduces SSD temperature, generates less heat, faster speed, and more LED status indicators. With M.2 New Specification Interface: PCI-E to NGFF riser card is a new type of solid-state interface card with M.2 new specification interface. PCI-E transfers data without accessing the SATA cable to connect to the motherboard.
