    Default Common ground

    Just a thought, the present ATX spec seems to have a common ground for all return voltages (the black wires).

    Does this not to some extent bring back some of the flaws of group regulation in the sense that a high current on one voltage rail will cause a voltage drop on the return ground that is seen by the other voltage rails? Perhaps each voltage should have their own ground wires.

    Reviews and test results of non-group regulated units surely don't show anything like that.
