PCIe x1 Dual Port Gigabit Ethernet Network Card with Realtek RTL8111F Chip, 1000Mbps PCI Express LAN Adapter for Desktop PC, Comes with Full & Low Profile Brackets

This PCIe x1 dual-port gigabit network card adopts mature Realtek RTL8111F main control chip, bringing reliable dual-gigabit wired network expansion for desktop computers lacking enough onboard LAN ports. Each RJ45 port supports automatic speed switching among 10Mbps, 100Mbps and 1000Mbps, meeting high-speed data transmission demands for file servers, monitoring hosts and multi-network access workstations.

Designed with universal PCIe x1 slot, the card can be mounted on any free PCI Express slot of the motherboard, no matter x4, x8 or x16 slots, without occupying high-speed graphics channel resources. Two matching metal brackets are included in the package: full-height bracket for regular ATX/MATX chassis, and low-profile short bracket for slim small form factor mini PCs, covering almost all desktop case types.

Built-in electromagnetic shielding structure effectively isolates signal interference from CPU, graphics card and power supply inside the case, avoiding network disconnection, packet loss and high latency during long-time continuous operation. It supports common network functions such as wake-on-LAN, VLAN and jumbo frame, suitable for office multi-line networking, NAS storage host, industrial monitoring equipment and game multi-network setup.

Mainstream Windows operating systems can automatically recognize the hardware after installation without complicated manual driver downloads. The metal baffle features good heat dissipation performance to keep the chip running cool under heavy network load. It is an economical dual-gigabit LAN upgrade solution for engineers, content creators and office users who need dual independent wired networks.
