Features 1. Comes with 4 power modules, 4 independent fuses, 4 solid capacitors, 2 USB3.0 19pin interfaces on the board. 2 USB3.0 19 Pin connectors: Allows you to expand 4 USB 3.0 ports to your desktop computer using 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 interference and greatly improve stability. 3. 4 Independent Fuses: Each interface is equipped with an independent protective fuse. When the external USB device is short-circuited and the current is too high, the current can be turned off immediately to protect the peripheral and the computer from damage. 4. 4 Solid Capacitors: Each interface is equipped with an independent regulator capacitor to ensure a smooth supply for each interface. And the capacitors using solid-state chips, 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 with 2A power supply, a total of 8A power supply. In addition, the inductor uses 12mm*12mm closed super power inductors.

When the external USB device is short-circuited and the current is too high, the current can be turned off immediately to protect the peripheral and the computer from damage. Once the fault is rectified, the system will automatically return to normal. 4 Solid Capacitors: Each interface is equipped with an independent regulator capacitor to ensure a smooth supply for each interface. And the capacitors using solid-state chips, 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 with 2A power supply, a total of 8A power supply. In addition, the inductor uses 12mm*12mm closed super power inductors. High-quality baffle: High-quality solid baffle, used to fix the expansion card on the chassis. And these baffles, treated with bending hardening 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. Specifications: Number of interfaces: 1 * PCI-E x1, 2 * USB3.0 19 pin connector Transmission speed: Up to 5 Gbps Power: 2A for each USB port System: winXP, win7, win8, win8.1, win10 Applicable slot: For PCI-E X1 X4 X8 X16 slot Low baffle length: 8cm Product size: Approx. 12cm (baffle) * 9cm * 6.9cm Package weight: 113g Package list: 1 x PCI-E to 2 Port 19Pin USB3.0 Card Adapter 1 x Low Profile Bracket 1 x CD 1 x Screw Note: 1.
