2.5G PCIe network adapter

The RIITOP RTL8125B adds a single RJ45 port that runs at 2.5Gbps, 1Gbps or 100Mbps over standard twisted-pair cabling. It fits any PCI Express x1, x4, x8 or x16 slot and works with Windows, Linux and macOS without extra drivers for most releases.

Build quality and connectors

The half-height PCB measures 71.5 by 50 by 1.6mm and carries one RJ45 jack with LED indicators for link speed and activity. Auto-MDIX and full-duplex support remove the need for crossover cables or manual port configuration. Wake-on-LAN and PXE boot are both implemented in hardware.

Thermals noise and power

Passive cooling keeps the card silent because no fan is fitted. The RTL8125B controller draws modest power from the PCIe slot itself, so no auxiliary connector is required. Operating temperatures stay low in typical desktop, workstation or server workloads.

商品問答

What IEEE standard limits the 2.5 Gbps speed on the RTL8125B adapter?

The card follows IEEE 802.3bz, which defines 2.5GBase-T operation over existing cabling.

Which PCI Express slot sizes accept this 71.5 mm × 50 mm card?

It fits x1, x4, x8 and x16 slots; the physical connector is x1 so any larger slot works.

How do you enable the PXE boot option after installing the driver?

Enter the system BIOS, locate the network boot or PXE setting for the RTL8125B controller, and set it to enabled before saving.
