Next-Gen 10Gbps Speed with Realtek RTL8127
Step up to true 10GbE wired performance. Powered by the latest Realtek RTL8127 controller, this PCIe network card delivers reliable data transfer rates up to 10Gbps — perfect for demanding NAS storage, home labs, competitive online gaming, and smooth 4K video editing.

Versatile Multi-Gigabit Auto-Negotiation
Seamlessly auto-negotiates across 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps. It matches your existing router, switch, or NAS speeds without manual configuration. For a stable 10G link, we recommend using Cat6a or Cat7 cables; high-quality Cat6 cabling can also work for flexible 10GbE upgrades over short to medium distances.
Flexible PCIe X4 Interface
Fits any available PCIe x4, x8, or x16 slot — no GPU lane compromise. A smart, space-saving upgrade for Mini PCs, ITX builds, compact workstations, and full-size towers alike. (Please note: not compatible with legacy PCI slots.)
Broad Operating System Support
Plug-and-play on Windows 11, 10, and Windows Server 2019/2022. Natively supported in modern Linux distributions with Kernel 6.x and above (Ubuntu, Debian, Fedora, etc.). For older Linux Kernel 5.x systems, drivers are available via Realtek’s official source code. Ideal for mainstream virtualization and DIY NAS setups.
Cool, Efficient & Easy to Install
The RTL8127 chipset runs with lower power consumption and less heat, built for reliable 24/7 operation. Both a standard bracket and a low-profile bracket are included, so you can install it in slim SFF cases or full-size desktop towers in minutes.
What's Included
Please Note:
For full 10Gbps speeds, a PCIe x4 (or larger) slot and Cat6a/Cat7 cabling are required.
The card will auto-negotiate down to the highest speed supported by your switch and cable — this is normal behavior.
