Feels kinda strange to be blaming a board maker for Intel's PCIe lanes limitation. And I thought AMD's USB woes made pretty obvious the PS/2 reliability advantage when OCing or benching.
You say the backplate is gawdy, but do you just sit there looking at the
back of your board?
Part of the reason this board runs cooler than almost all the boards out there is because Biostar evidently understands that PCB temps play a big part in VRM thermals, and made a large backplate that acts as an extended VRM heatsink. And it also uses a real finned stack over the main bank of SPSes. If companies like ASRock understood these design principles, they might not need to slap fans on all their shitty VRMs to achieve acceptable temps.
And that "dated-looking" BIOS has something that no other vendors still have on their products - in-BIOS fan control that works without forcing users to install garbage bloatware on their systems just to control RGB.
Granted, the board has no business being at $360, but you can say the same for every single Z590 board on the market.
