PCI-E to RJ45 Gigabit Ethernet Card with 3-Port USB 3.0 Hub, 10/100/1000 Mbps USB 3.0 Ethernet Network Adapter for Desktop PC Stable Wired Network Connection

This multifunctional PCI-E expansion card combines a Gigabit Ethernet controller and three independent USB 3.0 ports in one compact board, perfectly upgrading desktop computers with insufficient network interfaces and limited external USB ports. The built-in RJ45 network port fully complies with IEEE 802.3 standards, automatically switching between 10Mbps, 100Mbps and 1000Mbps transmission modes to provide smooth, low-latency wired network for online gaming, 4K video streaming, large file downloading and office data transmission.

Three outward-facing USB 3.0 ports offer a maximum theoretical transfer rate of 5Gbps, which is backward compatible with USB 2.0 and USB 1.1 devices. You can easily connect flash drives, external hard drives, keyboards, mice, printers, game controllers and other peripherals simultaneously without port congestion. Install by directly inserting the card into the standard PCI-E X1 slot on the desktop motherboard, most mainstream Windows systems can recognize the hardware automatically for driver-free quick setup.

Adopting industrial-grade control chip and reinforced PCB circuit board, the card features excellent anti-interference performance, stable continuous operation and effective reduction of packet loss and transmission lag. The metal baffle enhances heat dissipation and fixes the card firmly inside the chassis, ideal for office desktops, DIY assembly machines, industrial control hosts and media workstations to expand network and peripheral connection capabilities conveniently.
