Item Type: Expansion Card Model: U3142AC Interface: PCI-Ex4 (available for PCI-Ex8x16 video card interface) Extension Interface: Type-C x 1+ USB3.1A x 1 Main Control Model: ASM3142 Transmission Rate: 1000Mbps Supported System: For XP/WIN7/WIN8/WIN8.1/WIN10, etc. Supported Case: All sizes 1、ASM3142 main control chip. Adopt advanced technology of low voltage power supply. Support USB3.1 dual port, up to USB3.1 Gen-11 10Gbps. 2、Support two devices running simultaneously with Type-A+Type-C USB3.1 dual port, and maintain the compatibility with the existing USB peripheral products. 3、Independent voltage regulator capacitor. Each interface is equipped with an independent voltage regulator capacitor to ensure stable power supply for each interface. The capacitor is of solid-state patch type, which can withstand high temperature up to 250℃. 4、Independent protection insurance. When the external USB device is short-circuited or over-current, the power will be cut off instantaneously to protect the peripherals and the computer from damage, and automatically recover when there is no fault. 5、Equipped with 2 independent power management modules, supplying power without external power supply, so that the two interfaces can work independently without interference, more stable operation and more reliable to use. 6、The thickened immersion gold process makes the contact more reliable and the transmission more stable, not easy to cause packet loss and distortion, and easy to realize 10,000 times of plugging and unplugging, suitable for PCI-Ex4, x8, x16 slots. 7、Adopt imported alloy cooling fin with great heat conduction ability, which can efficiently dissipate the heat so that the expansion card is always at normal temperature and maintain stable operation. 1 x Expansion Card 2 x Screws 1 x Half Height Baffle 1 x Driver Disk
