For how easy it is to build a computer, we often don’t appreciate the electrical engineering that takes place to make that happen. For example, how does the motherboard manage the way your CPU gets power? Through a Voltage Regulator Module (VRM). But what is a VRM, and how does it affect your CPU performance? This guide aims to answer those questions.
What Is a VRM?
Your motherboard’s VRM is a crucial but underappreciated series of electronic components, including capacitors, chokes, and MOSFETs, that ensure your CPU or GPU receives clean power at a consistent voltage.
A poor VRM can lead to degraded performance and limit a processor’s ability to function under load. It can even lead to unexpected shutdowns, especially when overclocking the CPU. This can happen due to a poor VRM heatsink or insufficient VRM cooling.

How Does a VRM Work?
A VRM’s first job is to convert the 12-volt power from your computer’s power supply… Read more
