Feature:1. USB3.0 Controller: Four USB3.0 controllers, one bridge controller, each channel bandwidth does not share independent bandwidth and speed is not discounted.2. Main Control Chip: PCIE serial card adopts high quality main control chip, the chip is beautifully welded, the number of surrounding originals is sufficient, and the uniform and neat layout can eliminate interference to the great extent and improve stability.3. All Solidly Capacitors: PCIE serial card adopts all solidly capacitors, and each interface is equipped with an independent voltage stabilizing capacitor, which can ensure the stable power supply of each interface, and each interface is equipped with independent safety.4. High Temperature Resistance: The capacitor adopts solidly chip type and can withstand high temperature of 250 degrees, which is more stable and resistant to high temperature than ordinary capacitors.5. 3A Power Supply: The PCI Express card has a larger heat sink, and the heat dissipation effect is better. The card has its own power supply module, which can provide 3A power supply.Specification:Item Type: PCIE to USB 3.0Material: PCBBus Interface: PCI EX4 (Compatible with PCI EX4X8X16)Expansion Interface: External USB3.0 Interfacex4, Built in 19Pin Interfacex2Working Environment: 0 to 70Transmission Speed: 5Gbpsx4System Support: For win XP, for Win7P, for Win8P, for Win10, for LINUX, for ESxI, Etc..Package List:1 x CD Drive Disc1 x Riser Card1 x Screw Pack
