There was news that B660 motherboards may not have PCIe 5.0 functionality, and in fact, it’s slightly limited compared to the Z690 chipset, but the PCIe 5.0 x16 can still be found on the B660GTA motherboard. All other connections are compatible with PCIe 3.0 or 4.0, which is described in the specifications table.

Below you can see the rear IO shield and all available connectors. On the B660 motherboards, we can still find DVI and PS/2 ports. Higher models don’t have that, except for the top overclocking series where PS/2 is still used.
