Resistance also creates heat and it has to be reduced to a controllable level.

In order to provide every critical part of circuitry within the PCB, AOpen deploys a new design concept called “Power Bridge”. These bridges are strategically place within the motherboard design that provides both voltage and current to a targeted PCB region. This extra power is so pure that it contains no inherit noise when travel through VCC and ground plane.

The theory behind this is long transmission lines have considerable inductance and capacitance as well as resistance. When a current flows through the line, inductance and capacitance have the effect of varying the voltage on the line as the current varies.

AX3S Max/AX3S Plus II-U Online Manual The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium III, or when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and 2.140V. That is, the transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope, it shows the voltage transient is only 143mv even when maximum 18A current is applied.
