The VRM Voltage Regulator Module is a crucial component in modern computer motherboards, ensuring that the CPU receives a stable and precise voltage. Without a properly functioning VRM, processors may experience instability, overheating, or reduced performance.

A VRM works by converting the power from the PSU into a voltage suitable for the CPU. This process involves multiple phases, with each phase handling a portion of the total current. More phases generally mean smoother power delivery and better efficiency, which is essential for high-performance CPUs and overclocking scenarios.
