Features 1、Comes with 4 power modules, 4 independent insurances, 4 solid capacitors, 2 USB3.0 19pin interfaces on the board. 2 USB3.0 19 Pin Connectors: Allows you to extend 4 USB 3.0 ports to your desktop PC by means of the two internal 19‑pin USB3.0 ports. 2、High‑quality master IC: Advanced technology, low heat, fast, stable operation, perfect welding, excellent workmanship, uniform layout, neat, to maximize the interference, and greatly improve the stability. 3、4 Independent Insurances: Each interface is equipped with an independent protective insurance. When the external USB device is short‑circuited and the current is too high, the power can be cut off instantly to protect the peripherals and the computer fro 4、4 Solid Capacitors: Each interface is equipped with an independent regulator capacitor to ensure a smooth supply of each interface. And the capacitors using solid‑state chip, can withstand up to 250℃ high temperature. 5、Super power supply module: Each USB 3.0 interface is equipped with an independent power supply module, and each interface is exclusively provided 2A power supply, a total of 8A power supply. Besides, the inductor adopts 12mm * 12mm closed super‑power ind Specification Features: Comes with 4 power modules, 4 independent insurances, 4 solid capacitors, 2 USB3.0 19pin interfaces on the board. 2 USB3.0 19 Pin Connectors: Allows you to extend 4 USB 3.0 ports to your desktop PC by means of the two internal 19-pin USB3.0 ports. High-quality master IC: Advanced technology, low heat, fast, stable operation, perfect welding, excellent workmanship, uniform layout, neat, to maximize the interference, and greatly improve the stability. 4 Independent Insurances: Each interface is equipped with an independent protective insurance. When the external USB device is short-circuited and the current is too high, the power can be cut off instantly to protect the peripherals and the computer from being damaged. After the fault is removed, the system automatically returns to normal. 4 Solid Capacitors: Each interface is equipped with an independent regulator capacitor to ensure a smooth supply of each interface. And the capacitors using solid-state chip, can withstand up to 250℃ high temperature. Super power supply module: Each USB 3.0 interface is equipped with an independent power supply module, and each interface is exclusively provided 2A power supply, a total of 8A power supply. Besides, the inductor adopts 12mm * 12mm closed super-power inductors. High-quality baffle: High-quality fixed baffle, is used to fix the expansion card on the chassis. And this baffles, treated with hardening of bending on both sides, can withstand greater force. Gold-plated PCI-E x1 Interface: Thick gold-plated PCI-E interface for more stable contact and transmission. Not prone to data distortion.
