2.5GBase-T PCIe 3.1 Network Adapter

This PCIe 3.1 network adapter uses the Intel I225-V controller to add a single 2.5GBase-T RJ45 port to a desktop or workstation. It fits x1, x2, x4, x8 or x16 slots and includes a low-profile bracket for slim chassis. Supported operating systems include Windows 10, Windows 11, Linux, ESXi 7.0, OpenWrt, Unraid and Proxmox VE.

Passive cooling with low power draw

The card relies on passive cooling and the Intel I225-V's integrated MAC and PHY design, so it runs silently without a fan. Typical power consumption stays modest during normal 2.5G, 1G, 100M or 10M Ethernet traffic. Wake-on-LAN and TSN features operate without adding audible noise or measurable heat in everyday use.

Sustained multi-gigabit throughput under load

Under continuous 2.5Gbps transfer the controller maintains line-rate performance across 2500BASE-T, 1000BASE-T and 100BASE-TX links. PXE boot and full TSN offload remain stable during long sessions. The adapter is not suited for builds that require dual ports or fibre connectivity.

Questions about this item

How do I install the C&N 2.5GBase-T PCIe 3.1 adapter and which bracket screw do people forget?

Insert the Intel I225-V card into any PCI Express x1, x2, x4, x8 or x16 slot; the step most often missed is swapping the full-height bracket for the included low-profile bracket before securing the card to the chassis.

What maintenance or replacement will the Intel I225-V controller need after long-term use?

The controller has no moving parts or user-serviceable components; the only item that may need replacement is the supplied Cat8 Ethernet cable if its RJ45 connectors or jacket become damaged.

What limit appears first on the Intel I225-V during sustained 2.5 Gbps transfers?

The PCI Express 3.1 x1 link caps throughput at 5 GT/s, so the 2500 megabits_per_second line rate is the first ceiling you hit under continuous load.
