>Right, only the B650E chipset has official PCIe 5.0 support.

There is no AM5 chipset with PCIe 5.0 support. They are all on PCIe 4.0. The lanes come from CPU, they go to SSDs/GPU/chipset. All AM5 chipsets are linked to CPU via PCIe 4.0 lanes, none support PCIe 5.0 speeds.

edit: Not sure why the downvote, this is common information and it should be easy to link an AM5 motherboard that has x4 PCIe 5.0 downlink lanes to chipset. But they do not exist.
