C&N TXA307 5Gbps PCIe network card

This PCIe 3.1 x1 network adapter adds a single 5Gbps Ethernet port to a desktop or server. It uses the Realtek RTL8126-CG chipset and supports 5G, 2.5G, 1G, 100M and 10M link speeds over existing copper cabling. The card includes both full-height and low-profile brackets for standard and small-form-factor cases. It works with Windows 7 through 11 and Linux without extra drivers.

Practical limits of the PCIe 3.1 x1 interface

The PCIe 3.1 x1 slot provides 8 GT/s signalling, which caps real-world throughput below the nominal 5Gbps line rate. Cable length up to 100 metres on Cat5e depends on installation quality and link negotiation. Multi-gigabit speeds require a switch or router that also supports 2.5G or 5GBASE-T; a 1G port will fall back to 1G. Wake-on-LAN and PXE boot function only when the platform firmware enables them.

Single specification that decides fit

The card delivers one RJ45 port at 5000 megabits per second over PCIe 3.1 x1. Buyers who need more than one multi-gigabit port, fibre connectivity, or 10Gbps speeds should choose a different adapter.

Questions about this item

Should I pick the TXA307 or a different capacity for my 5Gbps upgrade?

The TXA307 is the only model listed; it provides a single 5Gbps RJ45 port with 2.5G, 1G, 100M and 10M fallback speeds.

What does the 5000 megabits per second rating deliver inside my PC?

It enables up to 5Gbps Ethernet throughput over Cat5e cabling up to 100 metres, with automatic negotiation down to 2.5G, 1G, 100M or 10M.

How does the PCIe 3.1 x1 interface limit real-world throughput?

PCIe 3.1 x1 supplies roughly 8 GT/s raw bandwidth, which comfortably exceeds the 5Gbps line rate so the card can sustain full wire speed.
