Why choose it

This card unlocks 5Gbps wired speeds without needing a new motherboard or switch—just a free PCIe x1 slot. The low-profile bracket makes it fit slim desktops and 1U servers, and driver support spans the most common operating systems.

Ideal use cases

• Adding multi-gigabit Ethernet to a workstation for large file transfers or video editing
• Upgrading a home server or NAS for faster backups and media streaming
• Building a budget-friendly 5GbE client for a small office network

Good to know

The card is powered entirely from the PCIe bus, so no extra power cable is needed. For full 5Gbps speed, use Cat5e or better cabling and a compatible 5GBASE-T switch or router.
