On-board design of 2 groups of high-power power supplies, using DC chips, integrated high-quality inductors, large-capacity filter capacitors; Each power supply supplies power to two USB ports to that the USB has enough power for external devices Supports USB3.2GEN2 10G TYPE-C and front TYPE-E interfaces, and uses professional 10G high-speed switching chips to stable and high-speed transmission of TYPC-C devices. Whether the main controller is stable depends mainly on the efficiency of the main controller power supply chip. The main controller is protected by the efficient and stable PWM synchronous step-down DC chip using a large . Each port uses a 2.2A protection chip. When an external device fault occurs, the protection chip be in a disconnected state to protect the device and the host. Multi-system compatibility: compatible with XP, Vista, 7 (driver required), 8, 10 system comes with driver Color:As Shown Material:PC Package Contents: 1 * PCIE Transfer Interface 3.2 Expansion Card Only the above package content, other products are not included.
