4-Port PCIe USB 3.0 Expansion Card with NEC Chipset, Bus-Powered High-Speed USB 3.0 Adapter for Desktop PC, No Extra Power Supply Needed

This internal PCIe USB 3.0 expansion card is equipped with reliable NEC chipset, a widely recognized stable solution for desktop USB expansion. It converts one PCIe X1 motherboard slot into four fully functional USB 3.0 ports to solve the shortage of built-in computer USB interfaces.

Each USB 3.0 port delivers up to 5Gbps bandwidth, greatly accelerating file copying for flash drives, portable hard disks, cameras and other peripherals. Different from power-hungry multi-port expansion cards, this model draws power directly from the PCIe bus without connecting extra power cords, simplifying internal chassis wiring and saving installation space.

The integrated metal shielding frame effectively blocks signal interference generated by graphics cards, power supplies and CPUs, preventing random device disconnection or recognition failure during long-time continuous use. It comes with a standard full-height baffle that fits all ATX, MATX and ITX desktop cases without modification.

It provides complete driver support for all mainstream Windows versions and Linux operating systems. After installing the matched driver, all four USB ports can work independently without bandwidth congestion. Perfect for office desktops, gaming PCs, live streaming workstations and industrial control hosts that need extra high-speed USB ports with simple wiring.
