CFNXKTWBR PCIe 3.0 USB and M.2 SATA Expansion Card

The CFNXKTWBR adapter takes an unusual two-in-one approach to desktop expansion. On a single PCIe 3.0 card it combines USB connectivity with M.2 storage, pairing two USB 3.0 ports and a USB Type-C connector with an onboard M.2 SATA B Key slot. That mix makes it a candidate for older or budget desktops that are short on modern USB ports yet still have a spare PCIe slot to fill. Rather than choosing between a USB expansion card and an M.2 adapter, this board attempts to cover both jobs at once.

Installation follows the familiar routine of any add-in card: seat it in an available desktop PCIe slot and secure the bracket. The M.2 slot accepts NGFF SATA solid-state drives in the four common lengths, 2280, 2260, 2242, and 2230, so a range of drives should physically fit. Because the slot is keyed for B Key SATA, it is intended for SATA-based M.2 SSDs rather than the faster NVMe drives that rely on an M Key connection, a distinction worth confirming against any drive you plan to install.

The product listing is light on detail, with no stated chipset, USB power figures, or benchmarked transfer speeds. Buyers weighing it against other USB port cards will want to treat the printed feature set as the full picture and match the card's ports and drive support to their build before purchasing.
