Single-port PCIe 2.1 Gigabit NIC

This single-port PCIe 2.1 network card uses a Realtek RTL8111H controller to provide one gigabit Ethernet connection. It fits desktop PCs and entry-level servers needing a wired network upgrade. The card includes both full-height and low-profile brackets for different chassis types. It serves as an economical replacement for faulty onboard LAN.

PCIe 2.1 x1 interface compatibility

The adapter uses a PCIe 2.1 x1 edge connector that works in x4, x8 and x16 mainboard slots. This single specification decides whether the card fits the available expansion slot in the target system. Driver support covers Windows 10, Windows 11, Windows Server and mainstream Linux distributions for broad deployment.

Low-power PCB with link LEDs

A compact low-power PCB design enables long-term stable operation without active cooling. LED link and activity indicators display real-time network status for quick fault checking. Features such as WoL, TCP/UDP checksum offload and 802.1Q VLAN reduce CPU load during daily data transmission.

Questions about this item

What does the 1000Mbps rating mean for daily desktop use?

The port auto-negotiates up to 1000Mbps full-duplex over Cat5e cable, giving a stable gigabit link for internet access, file sharing and light server tasks.

What does the PCIe 2.1 X1 interface limit in practice?

The card plugs into any X1, X4, X8 or X16 slot and runs at PCIe 2.1 X1 speed, which is sufficient for the single gigabit Ethernet port.

Which bracket should I use for a slim compact chassis?

The low-profile bracket fits slim compact chassis, while the full-height bracket suits regular desktop cases; both are included in the box.
