That is quite outdated already, modern CPUs/GPUs can eat up over 400-500 Amp already with voltages in range 0.7 - 1.1 VDC.
Typical high-end GPU have 10+ phases DC/DC, with integrated 80A rated power stages (contain low-side/high-side FET and driver in one package), digitally adjusted VRM controllers, etc.
One such example, next to last-year high-end GPU card.
