For sale: a TP-Link TX401 10 Gigabit PCI Express network adapter, brand new and still sealed in its shrink wrap. It has never been opened or installed.

This is a simple way to add a 10 GbE port to a desktop, NAS or home-lab machine without replacing the motherboard. The TX401 uses the Marvell/Aquantia AQC107 controller — the same class of 10GBASE-T chip found in many pricier cards — and it is well supported on Windows and Linux.

What’s in the box

  • TP-Link TX401 adapter
  • Full-height and low-profile brackets
  • 1.5 m CAT6A Ethernet cable
  • Quick installation guide and resource CD

The CAT6A cable matters: a standard CAT5e/CAT6 cable will not reliably carry 10 Gbps over any distance, so having the right cable in the box saves another purchase.

Condition

  • Brand new and unopened — the retail box is still sealed in shrink wrap.
  • Never installed or used.
  • The box has been stored indoors; no damage to the card or packaging.
  • Includes the manufacturer’s 2-year warranty, as printed on the box.
