QNAP QXG-5G1T-111C Single-Port 5GbE PCIe Network Expansion Card

The QNAP QXG-5G1T-111C is a network expansion card that brings 5 Gb Ethernet speed to any computer or QNAP NAS that has a PCIe 3.0 x1 slot. By adding this card, you can move large media projects, virtual machine images, or daily backups much faster than standard Gigabit connections allow.

Installation is straightforward. A single RJ45 port sits on the bracket, and the card works over existing Cat 5e cabling, so most offices and home labs will not need to run new wires. QNAP includes three brackets—a pre-installed low-profile version, a full-height option, and a special bracket for select QNAP NAS models—so the card fits neatly into compact desktops, workstations, and rack-mount enclosures alike.

The Marvell AQtion AQC111C controller inside the card negotiates 5 G, 2.5 G, 1 G, and 100 Mb speeds automatically. It runs smoothly on Windows, Linux, and QTS, allowing mixed-platform environments to upgrade with minimal effort. Whether you are a creative professional who edits directly from a NAS, a small business that needs faster backup windows, or an enthusiast building a high-speed home network, this card offers a simple path to multi-gig performance and comes backed by a limited two-year warranty.
