This article covers 10G デュアル RJ45 ポート PCI-E ネットワークカード Intel X540コントローラー付き Gigaplus X540-T2 10Gb イーサネットアダプター 10Gbe NIC 2個付き Windows.

Overview

The Gigaplus X540-T2 is a dual-port 10GbE network card built around the Intel X540 controller, offering a cost-effective way to upgrade your desktop or server to 10-gigabit connectivity. It uses a PCI Express 2.0 x8 interface and works in PCIe x16 slots, making it compatible with most modern motherboards. The card ships with both standard and low-profile brackets, so it fits in everything from full-size towers to compact 2U chassis. This NIC supports 100Mbps/1Gbps/10Gbps auto-negotiation on both RJ45 ports and is compatible with Windows, Linux, and VMware ESXi. Drivers are available directly from Intel’s website via the included QR code. For users who need high-speed LAN connectivity without spending a fortune, the X540-T2 is a practical, proven solution.

Connectivity & Compatibility

The Gigaplus X540-T2 connects via PCI Express 2.0 x8 (5.0 GT/s). It will operate in any PCIe x8 or x16 slot, but it will not work in legacy 32-bit PCI slots. Two independent RJ45 ports supporting 10GBASE-T, 1000BASE-T, and 100BASE-TX. IEEE 802.3an/ab/u compliant. Use Cat6a or Cat7 cabling for reliable 10 Gbps operation. OS support: Windows 7/8/10/11, Windows Server 2003/2008/2012, Linux (various distributions), and VMware ESX/ESXi. Intel X540 controller provides hardware offload for TCP/UDP checksum and segmentation.

Product Info

The exact model name is X540-2T. It has been available on Japan since approximately April 2024, with a price of around ¥31,265 (as of June 2026). The manufacturer (GigaPlus) offers lifetime technical support, though the standard warranty period is not clearly specified. Package contents: NIC card, standard bracket (pre-installed), low-profile bracket, and a quick-start guide with a QR code for driver downloads. Market positioning: entry-to-mid-range 10GbE NIC. By using the older Intel X540 chip (instead of the newer X550 or X710), the cost is kept low while still delivering genuine 10 Gbps throughput over RJ45. It is ideal for home labs, small NAS environments, and budget-conscious professionals who need wired 10GbE without investing in expensive SFP+ optics.

Best Use Cases

Home NAS / file server users: If you run a Synology, QNAP, or TrueNAS system with 10GbE, adding this card to your workstation or server eliminates the network bottleneck. The dual ports also allow link aggregation (LACP) for extra bandwidth or failover. However, note that the PCIe 2.0 x8 interface provides ~4 GB/s bandwidth, which is enough for two 10 Gbps ports running at full duplex simultaneously (each port 10 Gbps = 1.25 GB/s, total 2.5 GB/s). Virtualization homelab enthusiasts: Running ESXi or Proxmox? The X540-T2 is well supported and recognized by most hypervisors out of the box. You can assign each port to a different VM or bridge them for a virtual switch. The main caveat is heat — the X540 controller runs warm, so ensure adequate airflow in your chassis. * Budget 10GbE upgrades: If you can find a used Intel X540-T2 for less, that may be cheaper, but the Gigaplus variant costs roughly ¥31,000 new and comes with a low-profile bracket and support. For users who want a simple plug-and-play upgrade from 1GbE, this card delivers. Avoid this card if you need PCIe 3.0 or higher bandwidth for future-proofing, or if your motherboard lacks a free PCIe x8 or x16 slot.
