According to this: https://en.m.wikipedia.org/wiki/IEC_62196 the standard was updated in 2022 to support up to 1500V and 800A. If this can be achieved simultaneously it would be 1.2MW.
Whether it is necessary or realistic is another thing, but seems to be achievable without even changing the plug.
Well this is what we are accusing Microsoft of: Generating e waste, because they don't want to support older hardware.
