2.5 Gbps PCIe Network Card for Desktops and Servers

This Grwibeou adapter adds a single 2.5 Gbps RJ45 port to any system with a free PCI Express slot. It uses the Realtek RTL8125-CG controller to provide 10, 100, 1000 and 2500 Mbps Ethernet speeds. The card fits x1, x2, x4, x8 or x16 sockets and works with Windows 7, 8.1, 10, Server 2008, 2012 and Linux kernels up to 4.15.

Low-Profile Bracket for Small-Form-Factor Builds

An 8 cm low-profile bracket is included alongside the standard bracket, letting the card fit inside compact HTPC cases or slim workstations. Wake-on-LAN support allows remote power-on over the network. No additional software is bundled beyond the OS drivers listed in the specifications.

Check PCIe Slot Availability and OS Version

Verify your motherboard has an open PCI Express slot; the card will not work in legacy PCI slots. Confirm your operating system version falls within the supported Windows or Linux kernel range. Buyers needing multi-port connectivity or fibre interfaces should look elsewhere.

Questions about this item

Does the RTL8125-CG controller require any firmware updates or driver maintenance over time?

The card uses the Realtek RTL8125-CG controller with embedded memory and supports Windows 10, 8.1, 7, Server 2012, 2008 and Linux up to 4.15; driver updates follow the OS vendor schedule.

What limits sustained throughput on the 2.5Gbps RJ45 port during long transfers?

The single 2.5GBASE-T port negotiates at 2500, 1000 or 100 Mbps over standard twisted-pair cabling, so cable quality and link partner capability set the practical ceiling.

How much heat or noise does the low-profile bracket card produce when running continuously?

The passive RTL8125-CG controller has no fan; it draws power only from the PCI Express slot and adds negligible heat inside an HTPC or server chassis.
