Product information

Description

Sunix USB4300N is an internal PCIe interface card that provides four USB 3.2 Gen 1 (also referred to as USB 3.1 Gen 1 / SuperSpeed USB) ports with data rates up to 5 Gbit/s. The compact adapter (78 × 121 × 18 mm) installs in a desktop or workstation PCIe slot to add high-speed USB connectivity for external storage, cameras, audio devices and other peripherals. The card is compliant with PCIe host interfaces and carries CE and FCC certifications for regional regulatory compliance.

Advantages

The adapter delivers SuperSpeed USB performance up to 5 Gbit/s while remaining backward compatible with USB 2.0 and USB 1.1 devices, enabling a broad range of peripherals to operate without additional converters. Its internal PCIe form factor frees front-panel ports and provides a stable, permanently available connection for high-throughput devices. Plug-and-play support and hot-swapping simplify installation and everyday use in desktop systems.

Suitable for

Adding high-speed USB ports to desktop PCs or workstations
Connecting external storage devices for fast data transfer
Attaching webcams, digital cameras and multimedia peripherals
Expanding connectivity for audio interfaces, USB NICs and other USB accessories

Key specifications

Interface type: Internal PCIe card
USB standard: USB 3.2 Gen 1 (SuperSpeed, up to 5 Gbit/s)
Number of USB ports: 4 SuperSpeed ports
Backward compatibility: USB 2.0 and USB 1.1 devices supported
Dimensions: 78 × 121 × 18 mm
Compliance: CE and FCC certified

How to use

Power down the desktop, open the case and insert the Sunix USB4300N into an available PCIe slot on the motherboard. Secure the card to the chassis, close the case and power on the system. The operating system should detect the new USB controller and enable the ports via plug-and-play; install any vendor drivers if prompted to ensure full SuperSpeed performance. Connect USB devices to the card’s ports to expand the system’s external I/O capabilities.

Usage recommendations

For optimal throughput, connect USB 3.2 Gen 1–capable devices using high-quality SuperSpeed USB cables and avoid routing cables near large sources of electromagnetic interference. Use the internal PCIe slot closest to the CPU for reliable power and signal integrity, and install the latest system drivers or firmware provided by the platform or OS vendor when available.
