This article covers REDLUX 10GB PCI-e ネットワークカード (NIC) Intel X540チップ付き シングルRJ45ポート Intel X540-T1 PCIE 2.0 X8対応 Windows.

Overview

The REDLUX 10GB PCI-e Network Card brings Intel's X540-BT2 controller to an affordable single-port 10GBASE-T NIC. It connects via a PCI Express 2.0 x8 interface, making it a straightforward upgrade for desktops or servers that need a 10 Gbps wired connection. Priced around ¥8,651, it's one of the most budget-friendly ways to enter the 10G networking world. The card supports Cat.6a cabling for runs up to 100 meters.

Connectivity & Compatibility

This NIC requires a PCIe x8 or x16 slot (PCIe 2.0 or later). It negotiates at 10 Gbps or 1 Gbps only — there is no support for 2.5G or 5G multi-gig. OS compatibility is extensive: Windows 7/8/10/11 (driver installation required), Windows Server 2012/2016/2019, Linux, VMware ESX/ESXi, FreeBSD 11–14, and Ubuntu 20/22. Note that Dell and HPE servers with strict MCU requirements may not work; check with REDLUX before purchasing. The card is not hot-swappable.

Product Info

Released around 2024, the REDLUX 10G NIC sells for ¥8,651 on Japan (as of June 2026). It includes both full-height and low-profile brackets. Warranty details are not officially stated, but REDLUX generally offers a one-year warranty. This product sits in the entry-level segment of the 10G NIC market — competing with offerings from Zyxel and TP-Link — but the Intel X540 controller gives it an edge in driver maturity and stability.

Best Use Cases

Home lab enthusiasts who want to add 10 GbE to a NAS or server without breaking the bank will find this card a perfect fit. Small businesses upgrading their file server or backup network on a tight budget can also benefit from the low cost and solid performance. However, users who need multi-gigabit support (2.5G/5G) or full management features like VLAN tagging and remote boot should look elsewhere. The card is passively cooled, so it's relatively quiet, but it may run warm in poorly ventilated cases.
