SMUGDESK Dual Port 2.5GBase-T PCIe 3.1 x1 Network Adapter Intel I225-V / I226-V

SKU CH-TW92-8WV3V

Dual-port 2.5GBase-T PCIe 3.1 x1 NIC with Intel I225-V or I226-V controller, auto-negotiating 2.5G/1G/100Mbps speeds over existing cables

  • Dual 2.5G ports deliver 2.5× gigabit speed over existing Cat5e/Cat6 cables
  • PCIe 3.1 x1 fits x1/x4/x8/x16 slots with full-height and low-profile brackets
  • Hardware checksum and TSO/LRO offload cut CPU load during large transfers and 4K streaming
  • Jumbo frames, 802.1Q VLAN, LACP, WoL, PXE and 802.3az EEE for enterprise features
  • Drivers for Windows 10/11, Server, Ubuntu, CentOS, RHEL and Debian cover NAS, gaming and soft-routing

Dual-Port 2.5GBase-T NIC

This network adapter adds two independent RJ45 ports that auto-negotiate at 2.5G, 1G or 100 Mbps using Intel I225-V or I226-V controllers. It targets desktop users and small-business servers that need faster wired throughput without replacing existing Cat5e or Cat6 cabling. The card fits standard ATX and slim SFF chassis thanks to included full-height and low-profile brackets.

PCIe 3.1 x1 bandwidth ceiling

The single-lane PCIe 3.1 interface supplies 5 GT/s of raw bandwidth, which caps combined throughput below the theoretical maximum of two 2.5G links. Backward compatibility with x1, x4, x8 and x16 slots ensures physical fit, but the x1 electrical width remains the practical limit for sustained multi-gigabit traffic.

I225-V or I226-V controller variant

The adapter ships with either the original I225-V or the updated I226-V silicon; the latter lowers power draw and improves long-cable stability. Buyers who need guaranteed I226-V behaviour should verify the specific revision before purchase, as both versions share the same product listing.

Questions about this item

Should I pick the Intel I225-V or the I226-V version for my build?

Both controllers drive dual 2.5G RJ45 ports and share the same PCIe 3.1 x1 interface; the I226-V is the upgraded revision with lower power draw and better long-cable stability.

What does 2.5GBase-T actually deliver on my desk?

Each port auto-negotiates at 2500, 1000 or 100 Mbps, giving 2.5× the throughput of a standard gigabit NIC over existing Cat5e or Cat6 cabling.

Will the PCIe 3.1 x1 slot limit my 2.5G speeds?

The x1 lane at 5 GT/s provides ample bandwidth for dual 2.5G traffic, and the card fits x1, x4, x8 or x16 slots on any compatible motherboard.
