What Is a MOSFET? A Basic Definition

TJ Hooker

PC components like CPUs and graphics cards have strict operating voltages, so a motherboard’s VRM helps make sure this isn’t exceeded. MOSFETs are important to VRM functionality and have an impact on the amount of heat being generated by a VRM while it’s doing its job. MOSFETs can get quite toasty if you’re using a powerful graphics card, and a motherboard’s heatsink helps cool the MOSFETs and, thus, the VRM. In addition to keeping the overall system safe, keeping MOSFETs cool is also important for any type of overclocking.
This paragraph is sort of misleading. Your motherboard VRMs have nothing to do with your graphics card, and vice versa.
