Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A voltage regulator module or VRM, sometimes called PPM (processor power module), is a buck converter that provides a microprocessor the appropriate supply voltage, converting +5 V or +12 V to a much smaller voltage required by the CPU. Some are soldered to the motherboard while others are installed in an open slot. It allows processors with different supply voltage to be mounted on the same motherboard.
