Designing CPU power supplies that are efficient and are not just a great lot of buck converters in different phases (VRMs) is very hard.
On modern CPU that are all running at at around 1V, you get 1 amp = 1 watt
Switching element must survive that, and you have to be super responsive to transients, and you have to have super low ripple... I do not envy guys who make VRMs for GPUs and 200w server chips
