"So, where do you you expect it to generate the correct voltages for the
CPU?  In the RAM or something?"  :-)

Ah, I see.  Well this is more common on workstations than it was on PCs,
though even on PCs we now have ATX supplies generating 3.3vdc for the
CPU, which is much closer to what most CPUs need now.  Of course Intel's
constantly tuning little things so you still need a custom VRM on the
motherboard (nobody in their right mind want's to also change their PS
when they change their CPU! :-).  In the workstation world though it's
probaby common enough to generate exactly the right voltages for the CPU
from right in the power supply with no intervening VRM.
