PCIe 5.0 Gigabit Ethernet Expansion Card, PCI Express X1 RJ45 1000Mbps LAN Adapter for Desktop PC, Driver Supported for Windows 11/10/8.1/8/7, Windows Server 2022/2019/2016 and Linux OS

This PCIe 5.0 gigabit Ethernet internal network card is a reliable wired network upgrade accessory for desktop computers, perfectly replacing failed onboard LAN ports or adding an extra independent network interface for multi-network host deployment. Built on PCIe 5.0 high-speed bus architecture, it offers far larger transmission bandwidth than older PCIe versions, eliminating transmission bottlenecks when accessing NAS storage, transferring large files, streaming 4K videos and running online games, delivering lower latency and more consistent network performance.

The integrated RJ45 copper network port automatically switches between 10Mbps, 100Mbps and 1000Mbps working modes to match different routers, switches and Ethernet cables. The optimized internal chip effectively reduces CPU resource occupation under high network throughput, avoiding system lag or freeze, and maintains low-temperature operation for 24/7 non-stop running.

Installation is user-friendly: insert the card into the vacant PCIe X1 slot on the motherboard, fasten it with a fixing screw, connect the network cable and install the corresponding driver to complete configuration. It has powerful cross-system compatibility, fully supporting Windows 7, 8, 8.1, 10, 11 desktop systems, Windows Server 2016, 2019, 2022 server systems, as well as mainstream Linux operating systems including Ubuntu, CentOS, Debian and more.

Suitable for DIY assembled desktops, industrial control hosts, file storage servers, video editing workstations and soft routing equipment, this PCIe 5.0 gigabit NIC greatly enhances the stability and expandability of your computers wired network system.
