one benefit of atx3.0 is that you can likely get away with a lower total wattage PSU than if you have a atx2.0 design. Corsair recommends using 1200w on an overclocked RTX4090 if it's an atx2.0 unit, but you'll see some GPU companies say 850w or even 1000w is fine, they are assuming you have an ATX 3.0 unit
I look forward to a new wave of "why is my PC shutting down" posts in a few weeks
I don't think they are assuming you have a 3.0 PSU, that's why they are all including the adapter. Virtually no one has one and any new standard will be super slow to gain traction over many years IMO.
