TP-Link TX201, single-port 2.5-gigabit PCIe card with both brackets review
A single-socket 2.5-gigabit card whose Amazon.com page names its brackets and its operating systems in four short bullets, and never its controller, PCIe generation or lane count.
The title: TP-Link 2.5 Gbps LAN card, PCI-E, TX201. The four bullets: a 2.5 Gigabit Ethernet port for local transfers and games; backward compatibility with 1 Gbps and 100 Mbps; low-profile and full brackets; and Windows 11 to 7, Windows Server 2022 to 2008 R2 and Linux. The description reads “TX201”.

The questions that come up before an order
Which chip does it use?
The listing does not say. The VIMIN, YuanLey and GiGaPlus cards on this shelf name the Realtek RTL8125B.
Does it fit a slim case?
Yes: the third bullet says a low-profile bracket is supplied as well as the full one.
Our score
7.4/ 10
A plain 2.5-gigabit card with its brackets and operating systems stated. The cheaper RTL8125B cards here say more about what is on the board.
Against the rest of the network and storage gear
This network and storage gear share the category and the price bracket. Only what each one states is shown; an incomplete column would mislead.

Not published on the Amazon.com listing
Not published on the Amazon.com listing — no lane figure and no list of slots appears
2.5 Gigabit Ethernet, backward compatible with 1 Gbps and 100 Mbps — stated in the first and second bullets
One — the first bullet names a 2.5 Gigabit Ethernet port in the singular
Not published on the listing — the third bullet lists the connectors the card goes into and gives no generation for them, and no other bullet returns to the subject
Not published on the listing as a figure for the card — the third bullet names the connectors it fits as ×1, ×4, ×8 and 16, the last of them printed without its multiplication sign, and adds that a PCI slot will not do
2.5GBASE-T — stated in the third bullet in that form, with the title giving 2500 Mbps and the second bullet giving backwards compatibility at 2.5 Gbps, 1 Gbps and 100 Mbps
One — the third bullet turns a PCIe connector into one 2.5G Ethernet RJ45 socket, in the singular, and the title names a single interface adapter
Not published on the listing — the third bullet names the connectors the card supports and stops there, and no generation number appears in the title or in any of the five bullets
Not published on the listing as a figure for the card — the third bullet says it supports PCIe ×1, ×4, ×8 and ×16, which describes the connectors it will sit in rather than the lanes it asks for
2.5 Gbit/s over RJ45 — stated in the title as a 2.5-gigabit PCI Express Ethernet adapter at 2500 Mbps and in the first bullet as a 2.5 Gbit/s card; no BASE-T designation is printed anywhere on the page
One — the title names a single RJ45 LAN controller card, and no bullet prints a figure or returns to the subject
