Gigabit PCIe Network Adapter

This single-lane PCI Express x1 card adds a 10/100/1000 Mbps RJ-45 port to any desktop or workstation with an available PCIe slot. It is built around the Realtek RTL8111E controller and supports full-duplex transfer at up to 1000 Mbps in each direction.

Standard Bracket and Wide Slot Compatibility

The adapter ships with a full-profile bracket for typical tower chassis and fits PCIe x1, x4, x8 or x16 slots thanks to its x1 electrical interface. A single RJ-45 connector provides a secure wired link for servers, workstations or older PCs lacking onboard Gigabit Ethernet.

Low Power Consumption and Broad OS Support

The RTL8111E chipset keeps power draw minimal while maintaining line-rate throughput on Cat5e or better cabling. Drivers are available for legacy and current Windows releases, Mac OS, Linux and Unix, enabling plug-and-play deployment in mixed environments.

Questions about this item

What practical speed limit does the PCI Express 1.0a x1 interface impose on this RTL8111E card?

The single-lane PCIe 1.0a link runs at 2.5 Gb/s, so the card can sustain full-duplex gigabit traffic but cannot exceed that bus ceiling.

Which bracket size is supplied for mounting in a standard desktop chassis?

A full-profile PCI slot cover is included, matching typical full-height expansion slots.

How is the driver installed on Windows 10, and what step do users often miss?

Windows 10 usually loads the Realtek RTL8111E driver automatically; the common miss is forgetting to enable the adapter in Device Manager after insertion.
