LORDWORLD 2.5Gbps Dual RJ45 PCIe x1 Network Card

SKU CH-7ZVJ-X59J4

Adds two 2.5 Gbps Ethernet ports via a PCIe x1 slot using the Realtek RTL8125B chip with low-profile bracket included

  • Dual 2.5Gbps ports boost transfer speeds with Realtek RTL8125B chip
  • Low-profile and standard brackets fit diverse chassis sizes and layouts
  • PCIe x1 interface works in x1, x4, x8, x16 slots for broad compatibility
  • Auto-negotiation at 2500, 1000, 100, 10 Mbps supports Cat5e up to 100m
  • Windows 11, 10 and Linux support ensures wide OS coverage

Dual 2.5Gbps Ethernet adapter for desktop upgrades

The LORDWORLD card adds two 2.5Gbps RJ45 ports through a single PCIe x1 slot, targeting owners of motherboards that still ship with only 1Gbps onboard LAN. It uses the Realtek RTL8125B controller and auto-negotiates down to 1Gbps, 100Mbps or 10Mbps for legacy switches. Windows 11, Windows 10 and Linux are supported without extra driver hunts.

Low-profile and full-height brackets for any chassis

Both a low-profile bracket and a standard bracket are included, so the card fits slim HTPC cases as well as full-size towers. The PCIe x1 edge connector works in x1, x4, x8 or x16 slots, but it will not fit legacy PCI slots. On-board EMI shielding and a heatsink keep signal quality steady during sustained transfers.

100-metre reach on Cat5e or better cabling

The 2.5GBASE-T interface tops out at 2.5Gbps and relies on Cat5e or higher UTP runs no longer than 100 metres. It cannot exceed that bandwidth ceiling, so 10Gbps uplinks or fibre modules are not an option. Buyers needing more than two ports or 10Gbps speeds should look at a different adapter class.

Questions about this item

What PCIe slot types does the 2.5G card accept?

It fits any PCI Express x1, x4, x8 or x16 slot on a desktop motherboard; it will not work in legacy PCI slots.

Which brackets are included for mounting?

Both a standard-height bracket and a low-profile bracket are supplied, so the card fits full-size and slim chassis.

How is the driver installed on Windows 10 or 11?

Windows 10 and 11 load the Realtek RTL8125B driver automatically; on Linux the kernel module is built in, so no manual installer is required.
