This PCI Express 2.1 x1 2.5 gigabit network adapter adopts mature Realtek RTL8125 controller chip to deliver reliable 2.5GBase-T network speed, breaking the speed limit of traditional 1G onboard Ethernet. The single RJ45 port automatically matches 100Mbps, 1000Mbps and 2500Mbps bandwidth to connect with multi-gigabit network devices seamlessly.
Designed with standard PCIe 2.1 x1 bus, it will not occupy high-speed PCIe slots reserved for graphics cards or NVMe SSDs, making it an ideal cost-effective upgrade for desktops, workstations and entry-level servers. Built-in hardware checksum offloading eases system CPU burden during large file transfers, video streaming and high-concurrency data access.
It offers complete driver support for Windows Server series and mainstream Linux distributions including Ubuntu, CentOS and Debian, suitable for soft routing, network storage, small enterprise servers and gaming PC upgrades. Optimized PCB shielding layout minimizes signal interference and packet loss to maintain steady 24/7 continuous operation.
Comes with standard full-height metal bracket for quick chassis installation, a practical multi-gigabit wired expansion solution for devices without native 2.5G network ports.
