TP-Link TX401 10GB PCIe Ethernet Network Adapter

The TP-Link TX401 is a PCIe network adapter that brings 10 Gigabit Ethernet speeds to desktop PCs using 10GBase-T technology. It slots into a standard PCIe x1 interface and auto-negotiates across multiple speed tiers — 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps — so it works seamlessly regardless of your current network infrastructure. For users transferring large files between local machines, running network-attached storage, or simply wanting a faster connection, the TX401 provides a significant step up from typical gigabit adapters without requiring a complete network overhaul.

TP-Link includes practical extras that simplify setup. A 1.5-meter CAT6A Ethernet cable rated for 10Gbps comes in the box, eliminating the need to source a compatible cable separately. Both full-height and low-profile mounting brackets are provided, making the card a fit for standard towers and compact mini-tower cases alike. Quality of Service support allows the adapter to prioritize latency-sensitive traffic like gaming, and broad OS compatibility across Windows, Windows Server, and Linux means it should integrate into most desktop environments without issue. A two-year warranty and around-the-clock technical support round out the package.
