PRODUCT DESCRIPTION
TP-Link 10 Gigabit PCI Express Network Adapter (TX401) - 3 Years Local Warranty
The TX401 puts a 10GBASE-T port in a desktop or workstation over PCI Express 3.0 x4. It is the straightforward way to give one machine a 10-Gigabit link to a multi-gigabit switch or a NAS — over ordinary copper Cat6a rather than fibre, with a 1.5 m Cat6a cable supplied in the box.
10GBASE-T Over Copper, With Every Step Below It
The card negotiates 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T and 100BASE-TX, so it drops cleanly to whatever the switch on the other end supports. That matters when a 10G link is being added in stages: the workstation can go in first and still run at 2.5 or 5 Gigabit against existing multi-gigabit switching, then reach full rate when the switch is upgraded, with no card change.
PCI Express 3.0 x4 So the Bus Is Not the Limit
TP-Link specifies a PCI Express 3.0 x4 interface. The wider slot is what makes a full-rate 10G link realistic — a single-lane card cannot sustain it. Standards support covers IEEE 802.3, 802.3u, 802.3ab, 802.3bz, 802.3an, 802.3az and 802.3x, which is to say 10G copper, multi-gigabit, energy-efficient Ethernet and 802.3x flow control are all in the published list.
Standard and Low-Profile Brackets in the Box
Both a standard and a low-profile bracket are supplied, so the same card fits a full-height tower or a slim small-form-factor chassis without ordering a separate part. LED indicators report link and activity separately for 10 Gbps and for the 5, 2.5, 1 Gbps and 100 Mbps rates, so the negotiated speed is readable from the back of the machine rather than only in the operating system.
Windows, Windows Server and Linux Drivers
TP-Link publishes driver support for Windows 11/10/8.1/8/7, Windows Server 2019/2016/2012 R2 and Linux, and adds a footnote that drivers may need updating after an operating-system update. Current drivers are on TP-Link's Singapore download page, linked below. The card ships with a Resource CD as well, which few current machines can read — download rather than rely on it.
Ideal For
Singapore buyers moving large files on and off a workstation: video and photo editors working from a NAS, CAD and rendering machines, small-studio media servers, and anyone who has already bought multi-gigabit switching and wants the endpoints to use it. Supplied by SourceIT with local Singapore warranty and a GST invoice.

The interface row is reproduced exactly as TP-Link publishes it, reading "1x RJ45 Gigabit/Megabit Port" on a card whose own network-media row lists 10GBASE-T; the media and data-rate rows are the ones that describe the port's capability. TP-Link publishes no storage-temperature row, no weight and no chipset for this model, so none is claimed here. Published footnotes: "Maximum wired data throughput rates are the physical rates derived from IEEE Standard 802.3 specifications. Actual wired data throughput is not guaranteed and will vary as a result of environmental factors, Ethernet cable class, and computer performance." and "To ensure compatibility, you may need to update the adapter's drivers after an OS update."
Compatibility & Software Support

Frequently Asked Questions — TX401
Will it work in a PCIe x1 slot?
TP-Link specifies PCI Express 3.0 x4. A x1 slot does not have the bandwidth for a full 10G link, so fit the card in a x4, x8 or x16 slot.
What cable do I need?
Cat6a is the sensible choice for 10GBASE-T, and a 1.5 m Cat6a cable is supplied. Over short runs Cat6 will often negotiate 10G, but Cat6a is what to specify for new cabling.
Does it support macOS?
TP-Link publishes Windows, Windows Server and Linux driver support only, so we make no macOS claim. Check the support page for the current driver list before buying for a Mac.
What warranty does SourceIT provide?
Three years local Singapore warranty. Every TX401 sold by SourceIT comes with a GST invoice.
Can SourceIT supply the switch to go with it?
Yes. Send us the number of 10G and multi-gigabit ports you need and we will quote the adapters, switching and cabling together.
