10G Ethernet Adapter

The fenvi PCIe network card adds a single 10GbE RJ45 port to a desktop, server or workstation. It targets users who need faster wired links for NAS access, large file transfers or virtualisation workloads. The board draws power from the PCIe slot and ships with both full-height and low-profile brackets.

PCIe Gen3 x4 Interface

The card uses a PCIe Gen3 x4 connection that also fits x8 and x16 slots and supports PCIe Gen4 x2 mode. This bus width is the specification that determines whether the adapter can deliver full 10G throughput in a given system. No external power connector is required.

Thermals and Power

The Realtek RTL8127 controller runs on 3.3 V supplied by the PCIe bus without an auxiliary power cable. Passive cooling keeps the card silent in normal operation. Driver support spans Windows 10/11, Windows Server 2016/2019/2022, Linux kernel 2.6+ and common hypervisors.

Questions about this item

What does the 10GbE rating mean for actual transfer speeds in a desktop or server?

The card auto-negotiates at 10G, 5G, 2.5G, 1G, 100M or 10M, so real-world throughput matches the link partner and cabling used.

How does the PCIe Gen3 x4 interface affect the maximum bandwidth available?

Four Gen3 lanes at 8.0GT/s per lane give enough headroom for full 10GbE line rate; the card also works in x8 or x16 slots and supports Gen4 x2 mode.

Which bracket do I use to install this card in a low-profile chassis?

The box includes both a full-height 120mm bracket and a low-profile 80mm bracket; swap to the 80mm bracket for slim cases.
