    But I think we are drifting off the original topic.
    Drifting off topic provides for some the most entertaining reading on this forum!

    I've been censured for doing so more than once.

    Depends on the polarity of the diodes. With equal loads on each half, you could bypass the neutral altogether.
    But we are discussing PC supplies and it isn't likely that their PSUs will be half wave rectifiers.

    But with switch mode power supplies, don't they have like controlled rectification passing only current at various points in the cycle then shutting off at zero crossing. If when they pass current is not equal in magnitude with the other line's load current at that instant, then the 'average' neutral current is greater than the 'average' current of each line.
    I will have achieved my life's goal if I die with a smile on my face.

    Most I have dealt with have full wave rectification.
    I readily accept that I am not an expert in that field.

    This whole variation was proposed more as a theoretical oddity contradicting overstated generalizations than as a practical problem.
