does Ethernet use 1 PCIe lanes?

[tomg1234]

im running tight for PCIe lanes and does a wired ethernet cable plugged into the IO of the mobo use any PCIe lanes from the CPU? so basicly can i get internet without using a PCIe lane????
thanks for reading btw <3

The ethernet port does not affect the lanes of your PCIe slots. Only cards that you plug into your PCIe slots affect those PCIe lanes.

Everything else like SATA, Ethernet and USB use PCIe lanes from the chipset. These lanes are specific to I/O ports, and are never used by the PCIe slots.

Your not using a card so your fine. 😀

The ethernet port is one of the "plug-ins" in your motherboard. It is not a separate card. You shouldn't worry.

It really depends on how it was implemented by your motherbd.
For instance Current Gen Intel boards have PCIE lanes direct from the cpu for the GPU(s) and then more from the chipset to run all the peripherals. These peripherals can be wired PCI or PCIE depending on the age of the board and what the manufacturer chose for the actual chips being used. You should have a diagram/drawing of how the board is 'wired' in your users manual.

Something like this but the manufacturer would have even more off the Chipset, like audio, extra usb, maybe some sata's....

But to answer your question, if its a pcie NIC chip that they used then it would be 1 lane.
