2.5Gbps PCIe network card

This single-port RJ45 adapter adds a 2.5Gbps wired link to any desktop with a free PCIe x1 slot. It suits home-office users, small-business workstations and NAS builders who need faster file transfers than standard gigabit but do not require multi-port server hardware.

PCIe x1 slot requirement

The card occupies one PCIe x1 lane and draws power directly from the bus so no auxiliary cable is needed. A single RJ45 jack connects to a 2.5GbE switch or router, freeing the motherboard's onboard gigabit port for a separate network or management traffic.

Sustained 2.5Gbps throughput

The Realtek RTL8125GB controller maintains line-rate 2.5Gbps during long copy jobs and backup windows without throttling. Wake-on-LAN support lets the host sleep until network activity arrives, keeping power draw low when the link is idle.

Questions about this item

What limits sustained throughput on the Realtek RTL8125GB controller?

The PCIe x1 link and the 2.5 Gbps PHY set the maximum sustained rate.

How much noise or heat does the card produce under continuous load?

It has no fan and draws power only from the PCIe slot, so it runs silently with minimal heat.

What slot and cable must the desktop already have for this adapter to work?

A free PCIe x1 (or larger) slot and a Cat 5e or better RJ45 cable are required.
