The purpose of the caps that are close to the CPU is to reduce the
ripple on the processor power line to tolerable levels. The processor
can go from zero to 40 amps at anywhere from zero (ground bounce) to
GHz rates. The capacitors have to smooth all that out. Basically,
they form an energy storage system to deliver power during the high
current spikes to the power hungry CPU.

40A? Try 110A! Take a look at page 82.

For the high end 130W Xeon over 200A:
