Yes....

There is a voltage regulator on the PCB real close to the cpu
socket that generates the 1.57V @ 60A (or something similar).
The tolerances required mean it has to be physically close to the
cpu itself.
This regulator is powered from the 12v supply of the cheap
nasty PSU in the top of the case.
