1. A computer system comprising:

  • a multiplicity of PC-CPU motherboards, each of the multiplicity of PC-CPU motherboards includes a CPU processor having electrical circuitry interconnected with the processor, and a power-input connector connected to the circuitry for use in the supply of electrical power to power the respective motherboard;

    an electrical power-supply means for affording fault-tolerating redundancy for supplying electrical power;

    a mounting means for mounting the motherboards together with the power-supply means as a single unit; and

    a wiring means for connecting the power-supply means n common to the power-input connectors of the motherboards for powering the motherboards in parallel with one another;

    and wherein the power-supply means comprises a plurality of pairs of power-supply modules, means coupling the two power-supply modules of each said pair together for supplying power in parallel with one another and wherein the wiring means couples the pairs of power-supply modules together in parallel with one another for supplying power to the motherboards in parallel.
