— presence of at least one USB 3.2 gen2 connector on the back of the controller.USB (all versions) is the most popular modern interface for connecting external peripherals. And USB 3.2 gen1 (formerly known as USB 3.1 gen2 and USB 3.1) is a further development of this interface, after USB 3.2 gen1 (see the relevant paragraph). In this version, the maximum data transfer rate has increased to 10 Gbps; in addition, connectors of this type may provide support for USB Power Delivery technology, which allows you to output power up to 100 W per connector. (However, the presence of Power Delivery is not strictly required, it is better to specify it separately).
Separately, it is worth noting that the connection in USB 3.2 gen2 format can also be carried out via USB-C connectors. However, such connectors are practically not found in PCI controllers, so in this case we mean classic, full-sized USB sockets (the so-called USB A).
