2.5G PCIe Network Adapter for Desktops

This PCIe x1 network card adds a single 2.5GbE RJ45 port to a desktop motherboard. It targets users who want faster wired throughput than standard Gigabit without moving to 10GbE. The board includes both a standard and a low-profile bracket for different case heights. It is not for buyers who need multiple ports or fibre connectivity.

PCIe x1 Slot Limits and Cabling Rules

The card fits any PCI Express x1, x4, x8 or x16 slot but will not work in legacy PCI slots. It requires Cat5e or better UTP cable and supports links up to 100 metres. Auto-negotiation falls back to 1Gbps, 100Mbps or 10Mbps when the partner device cannot run at 2.5Gbps. Electromagnetic interference shielding and a heatsink keep the Realtek RTL8125B controller stable under load.

Realtek RTL8125B Controller Decides Compatibility

The RTL8125B chip handles 2.5GBASE-T, IEEE 802.3bz, full-duplex flow control, VLAN tagging and PXE boot. Driver support covers Windows 11, Windows 10 and Linux kernels. If your operating system lacks an in-box or upstream driver for this controller, the adapter will not function.

Questions about this item

Should I pick the low-profile bracket or the standard bracket for my case?

The card ships with both brackets, so you can swap to whichever matches your chassis height.

What real-world throughput does the 2.5 Gbps rating deliver inside a desktop?

It connects at up to 2.5 Gbps over Cat5e or better cable, with auto-negotiation down to 1 Gbps, 100 Mbps or 10 Mbps.

Which PCI Express slot versions does the x1 interface work with, and what speed ceiling applies?

The x1 connector fits x1, x4, x8 and x16 PCIe slots and runs at the slot's native PCIe 2.5 GT/s per lane.
