I’m going to copy two comments from TPU that i think are the most accurate regarding this proposal:

This doesn’t solve anything at all. You still have to plug power into the motherboard, likely via the problematic 12V6X2 connector once they extend it beyond 250W. Now you also need to dedicate additional (expensive) PCB layers and throw a lot more copper traces (expensive) at it too. It’s just a glorified extension cable that adds another connector to the equation. Why go from the PSU directly to the GPU when you can now do it with extra steps!! (/s) Cable still required, but now you need a new motherboard, too… Why? Because cables are evil, apparently and this fits the dumb BTF form factor that’s all about form over function, for people with infinite wallets.

This is a stupid idea. It should be separate as always. It also makes problems worse if connector-gate happens again, as now you fry a much larger PCB instead of tiny GPU board. And high power means you need to worry about heat on the mobo now too. It makes repair difficult too. But I’m not surprised. Asus always sucked on the user friendly aspect. Worst customer support. Apparently that’s the trend to keep up with the “You’ll own nothing and be happy” motto of stream everything, throwaway everything, get in debt all the time mentality.
