  • 5Gbps auto-negotiated wired speed via RTL8126 controller
  • PCIe 3.1 X1 fits X4 X8 X16 slots for flexible install
  • PXE boot enables remote diskless startup and batch deploy
  • Low-profile bracket included for slim and standard chassis
  • Windows and Linux driver support for plug-and-play use

5G Multi-Gigabit PCIe Network Card

This PCIe 3.1 X1 network card uses the RTL8126 controller to deliver a single RJ45 port that auto-negotiates 5G, 2.5G, 1G and 100Mbps speeds. It fits both standard and slim chassis thanks to an included low-profile bracket. The card targets desktop users, small-office NAS builders and IT teams needing PXE boot for diskless or batch deployments. Windows and mainstream Linux distributions are supported out of the box.

Thermals, Noise and Power Draw

The adapter has no active cooling and draws power solely from the PCIe slot, so it adds no audible noise to the system. Hardware offload reduces CPU occupancy during sustained high-speed transfers, keeping thermal load on the host minimal. Typical operation stays within the limits of the PCIe 3.1 X1 interface without requiring auxiliary power connectors.

Low-Profile Bracket and PXE Boot

A dedicated low-profile bracket is supplied, allowing installation in compact cases where a full-height bracket would not fit. Integrated PXE boot enables network-based OS deployment and diskless startup, useful for server clusters and managed workstations. Driver packages for Windows and common Linux distributions are included for plug-and-play setup. No cables, mounting screws or additional software utilities are bundled.

Questions about this item

How do I install this PCIe 3.1 X1 network card and which bracket should I use?

Insert the card into any PCIe X1, X4, X8 or X16 slot, then attach the included low-profile bracket for slim chassis or swap to a full-height bracket for standard cases.

What maintenance will the RTL8126 adapter need over time?

No scheduled maintenance is required; keep the RJ45 port dust-free, use Cat5e or Cat6 cables, and update the Windows or Linux driver when a new version is released.

What limits sustained throughput on this 5G Ethernet card?

The PCIe 3.1 X1 link caps maximum throughput at about 8 Gbps, so the RTL8126 controller will hit that bus ceiling before its own 5 Gbps PHY limit during continuous heavy transfers.
