SKU CH-3YE5-2SAVK

Adds a single gigabit RJ45 port to a desktop via a PCIe x1 slot using an RTL8111H controller

  • Gigabit speeds up to 1000 Mbps via RTL8111H chip
  • PCIe x1 slot adds a single RJ45 port to desktops
  • Supports 10, 100 and 1000 Mbps networks
  • RTL8111H controller provides reliable wired connectivity

PCIe x1 Gigabit RJ45 adapter

This PCI Express x1 card adds a single RJ45 port for 10/100/1000 Mbps wired networking. It uses the RTL8111H chip and is intended for desktop systems that lack onboard Ethernet or need a second wired link. The low-profile bracket fits standard and slim cases alike.

Open x1 slot required

Installation needs one free PCIe x1 slot and a driver supported by the operating system. The adapter provides a standard Gigabit Ethernet connection without occupying a USB port. It does not supply Power over Ethernet, wireless capability or multi-gigabit speeds.

Questions about this item

Will the PCIe x1 lane cap throughput before the 1000 Mbps port saturates under sustained load?

The card uses a single PCIe x1 lane which provides more bandwidth than the 1000 Mbps Ethernet limit, so the port saturates first.

Does the RTL8111H chip run hot or need active cooling when the link stays at 1000 Mbps all day?

The RTL8111H is a low-power controller that operates without a heatsink or fan; it stays cool during continuous 1000 Mbps traffic.
