2.5Gbps PCIe network card for desktop upgrades

The SMUGDESK TXA092 adds a 2.5Gbps RJ45 Ethernet port to a desktop PC through any PCIe x1, x4, x8 or x16 slot. It uses the Realtek RTL8125B controller to auto-negotiate 10, 100, 1000 and 2500Mbps speeds with existing Cat5e or Cat6 cabling. The card targets users who need faster NAS access, large file transfers or lower latency gaming beyond standard 1Gbps onboard LAN.

Low-profile bracket fits compact cases.

Installation is a simple internal fit into a spare PCIe slot, and the included low-profile bracket suits small form factor chassis. The card is plug-and-play after the appropriate driver is loaded for Windows, Linux or macOS. Common issues arise only if the driver is missing or the switch port does not support multi-gigabit negotiation, limiting the link to 1Gbps.

Ideal for NAS, gaming

This adapter suits builders upgrading a desktop for 2.5Gbps wired networking, especially with compatible NAS devices or switches. It supports 16K jumbo frames, VLAN tagging and Wake-on-LAN for unattended management. Buyers needing 10Gbps or higher throughput, fibre connectivity or additional ports should consider other solutions.

Questions about this item

How can I confirm the RTL8125B card is running at 2.5Gbps after I install it?

Check the link LED on the bracket; it lights solid for a 2.5Gbps link and blinks during activity. In the OS network adapter properties the speed should read 2500 Mbps when connected to a 2.5G switch with Cat5e or Cat6 cable.

What comes in the box and what must I source separately?

The package includes the PCIe x1 network card with a standard bracket and a low-profile bracket for small cases. You must provide a Cat5e or Cat6 Ethernet cable and a free PCIe x1, x4, x8 or x16 slot on the motherboard.

Which version of this adapter should I choose for a compact mini-ITX build?

The single TXA092 model fits all builds; swap the standard bracket for the included low-profile bracket to clear a mini-ITX chassis while keeping the same RTL8125B controller and RJ45 port.
