4 Port PCI-E USB 3.0 Expansion Card, PCIe X1 USB 3.0 Hub Controller Adapter, SuperSpeed 5Gbps PCI Express USB3.0 Card for Desktop PC, Internal PCIe 1X USB Expansion Adapter Supporting Multiple USB Per

This 4-port PCI-E USB 3.0 expansion card is a practical internal PCIe X1 adapter to solve the problem of insufficient native USB ports on desktop computers. Designed for standard PCI Express X1 slots, it is also backward compatible with X4, X8 and X16 motherboard slots for flexible installation.

Equipped with four independent USB 3.0 Type-A ports, the card delivers a maximum transfer rate up to 5Gbps, greatly cutting down waiting time when copying high-capacity photos, HD videos and large game files. It is fully backward compatible with USB 2.0 and USB 1.1 peripherals to support all your existing USB accessories.

Built-in stable control chip and protective circuit design provide over-current and short-circuit protection, effectively avoiding hardware damage caused by unstable current during long-time continuous use. The standard full-height metal bracket fits most PC tower cases firmly without loosening.

No complicated driver configuration is required for mainstream Windows operating systems, and complete driver support is offered for Linux platforms. Simple plug-and-play operation allows you to connect external hard drives, gaming peripherals, printers, cameras and more at the same time.

Compact PCB layout saves internal chassis space, making it an ideal upgrade accessory for office desktops, gaming rigs and industrial hosts that need extra USB expansion to connect multiple devices simultaneously.
