Question How Important does VRM Amps Really Matter [50A 60A 105A]

[tomyhardz]

Power demanding processor need higher VRM in order to work efficiently,
After digging deep found there Amp rating for those VRM
so how the major role these Amps play... is it only for overclocking.
Is there any minimum/required for Amps 13 &14th Gen 600k,700k,900k series processors VRM....???

The current ratings of the VRM FET's or DrMOS power stages are critical but that is only part of the story for total power handling of the VRM. Equally important is number of phases and heatsinking on the devices. Also a factor is air-flow through the case so that the heat sinking can be effective; that is something a system builder can directly affect.

Very important, but much less obvious, is voltage stability for high current transient events. That's a function of the VRM controller and turn on/turn off characteristics of the FET's along with basic design topology of the VRM including filtering and even mother board design.

Power handling is important when overclocking most any CPU but many high core-count CPU's also need extremely capable VRM's simply to operate effectively at rated clocks, without long term damage to the VRM and motherboard.
