Actually, this is already being done in your PC now.  PC power supplies only 
generate 3.3V, 5V, and 12V; they don't directly generate the CPU and RAM 
voltages.

Beginning with the Pentium 4 and Athlon 64 chips, most motherboards use a 12V 
input to the CPU core regulators; prior motherboards either used the 3.3V or 
5V outputs of the power supply regulated down to the CPU core voltage.

There are little 12VDC 'paddleboards' now that plug into an ATX motherboard 
plug; 200W units are very small.  See the units at mini-box.com for 
comparisons; the PSU board is part of the ATX plug itself in most cases.
