PCIe 3.1 2.5GBase-T ネットワークアダプター Intel I225-V

This article covers PCIe 3.1 2.5GBase-T ネットワークアダプター Intel I225-V.

Overview

The ULANSeN PCIe 3.1 2.5GBase-T Network Adapter is a single-port wired LAN card powered by the Intel I225-V or I226-V controller. It supports up to 2.5Gbps data transfer, offering 2.5 times the bandwidth of traditional Gigabit Ethernet (1Gbps). Simply plug it into a PCI Express x1 slot to add high-speed wired networking to your desktop PC. This adapter now ships primarily with the I226-V, which replaces the I225-V with improved error rates and lower power consumption. It supports 2500BASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T, and can achieve 2.5Gbps over existing CAT5e cabling.

Connectivity & Compatibility

Interface: PCI Express 3.1 x1 (works in x1, x2, x4, x8, x16 slots) Supported OS: Windows 10/11, Linux, ESXi 7.0, OpenWrt, Unraid, PVE Standards: IEEE 802.3 (10BASE-T), 802.3u (100BASE-TX), 802.3ab (1000BASE-T), 802.3bz (2500BASE-T) Accessories: Low-profile bracket included * Features: PXE boot, Wake-on-LAN, TSN (Time-Sensitive Networking)

Product Info

Release: 2022 onward (I226-V model widely available from 2023) Price: Approximately ¥10,147 on Warranty: 180-day assurance from the seller Package contents: NIC card, low-profile bracket * Market position: Mid-range. It offers an affordable entry into 2.5GbE networking with a trusted Intel chipset.

Best Use Cases

Upgrading a desktop PC with only 1GbE onboard LAN to 2.5GbE for faster NAS or file server transfers. Creative professionals or remote workers who frequently transfer large files and need stable, high-bandwidth wired connectivity. * Home lab or small server users running ESXi, Unraid, or OpenWrt who need additional NIC ports. The included low-profile bracket makes it suitable for compact cases.

Things to Consider

This is a single-port NIC. If you need dual ports, look for a different model. To achieve 2.5Gbps, your switch, router, and NAS must also support 2.5GbE. In a 1GbE environment, the card will operate at 1Gbps. The Intel I225-V and I226-V have had some driver stability reports in certain environments, but recent drivers have addressed most issues. Windows 10/11 typically recognize the card with built-in drivers. The low-profile bracket is included, but the card comes with a standard-height bracket pre-installed. No extra full-height bracket is provided.
