4 Port USB 3.0 PCIe X1 Expansion Card, Renesas (NEC) Chipset, 15-Pin SATA Power Supply, SuperSpeed 5Gbps PCI-E USB Controller Adapter for Desktop Motherboard

This 4-port PCIe USB 3.0 expansion card is built with mature Renesas (NEC) control chip, a reliable upgrade solution for desktops lacking enough USB ports. It expands one PCIe slot into four independent external USB 3.0 Type-A ports, supporting up to 5Gbps ultra-fast data speed and UASP protocol, bringing up to 70% faster file copy performance than ordinary USB 3.0 adapters.

Different from regular PCIe USB cards relying solely on slot power, this model comes with a dedicated 15-pin SATA power input to draw stable current from PC power supply. It eliminates device unrecognition, drop connection and speed reduction when running multiple power-hungry peripherals such as external SSDs, mechanical hard drives, USB docking stations and industrial cameras simultaneously.

Designed for PCIe Gen2 X1 slot, it works seamlessly with all mainstream ATX, MATX, Mini-ITX motherboards and is backward compatible with X4/X8/X16 PCIe slots. It includes a full-height standard bracket and supports low-profile installation for slim small chassis. The built-in overcurrent protection circuit safeguards your USB devices and motherboard from voltage surges.

Plug-and-play installation without complex wiring, fully compatible with Windows 7/8/10/11 and Linux operating systems. Ideal for gaming PCs, video workstations, office desktops and industrial host equipment to expand high-speed wired USB connectivity.
