Such an odd choice of GPUs, jumping from the top end xx90/x900 down to xx60/x600, skipping cards like the 4070 and 7800XT entirely. Side from some 1% low numbers I don’t see anything new here compared to Techpowerup, for example.

Most likely 12VHPWR with recessed pins (aka 12V-2x6) and require stricter quality control from their partners. They aren’t going back to 8 pins.

My Aorus B550i no longer experience USB issues with F17 BIOS. Though Gigabyte do multiple revisions on the same board so not all revisions are guaranteed to be safe from this issue.
