DescrtionConformsTo Expre standard version 2.0.Meets Universal Serial Bus 3.0 standard.USB 3.0 interface nsmiion rate could reach 5Gbps, downward compatible with USB 2.0 / 1.1.A USB device to be connected simultaneously 7tlg.USB interface could provide 5V2A power supply to the external device.With two power module, not need ex power supply.Supports Linux / Windows XP / 7/8 / 8.1 / 10 and 32 bit or 64 bit WHQL certified driverFQAQuestion 1: Why is power-free better than external power supply?Answer: External power supply s wires to connect external 5V to the interface. Voltage lo will occurthrough wires. The larger the load, the greater the lo, the more unstable there will be.The power-free board takes 12V. Ar voltage reduction, interference removal and voltage stabilization,the output is stable 5V, and lo compensation is added, so there will be no shortage of power supply.Question 2: Will the main board interface power affect the main board?Answer: The industry standard of -e interface of is to provide 75W power. The full load workof extended card is 40W, which occupies only half of the design standard. Normal rarely exceeds 10W, sothere is no need to worry about the impact on .Question 3:What are the advantages of this product?Answer:6A Independent Power Supply2-phase power supply module2-way independent power supply2 Independent Insurance2 working independentlyMutual non-influenceSay goodbye to the shortage of power supplyWhat's Included1 x 7 Port USB3.0 Expre Card1 x Driver CDModel B Descrtion100% and high quality.Supports Expre 2.0 X1e, can nsferring up to 5Gbps.Supports USB 3.0 specification type A connector X 7 ports.Backward compatible with USB 1.1/USB 2.0.Supports the following speed data rate: Low-speed(1.5Mbps)/Full-speed(12Mbps)/High-speed(480Mbps)/r-speed(5Gbps).Supports low profile. 15-PIN power supply, sufficient and stable power supply to ensure stable operation of equment.Hot-swappable, plug and play, low power consumption, envmental protection and energy-saving products, low heat, stable.Supports external power plug in order to supply power for each USB 3.0.Up to 900mA Max/port.System Requirements:PC with 512MB of RAM and 1.0GHz or faster proceor.One available Expre 1.x/4.x/16.x slotSystem Support: Windows XP / Vista / Windows7 (32/64 bit)/Window (32/64 bit).Please Note:1.
