I've been trying to learn more about GPUs and Motherboards on a circuit-level. In my search I found a pretty awesome article about GPU Voltage Regulator Modules. It's a good crash course for those of you that are curious to learn the inner workings on a more detailed level.

The Voltage Regulator Module or VRM is a device that performs DC-DC conversion (DC = Direct Current). This conversion is fundamental because many chips, like the GPU in our case, do not operate at 12V or 5V but at lower voltages like 1V. Then devices to reduce the voltage are required and these devices are the famous VRMs. So a VRM is a DC-DC converter. The other goal of a VRM is to provide a constant DC output voltage as well as providing a lot of current (amperes) to the GPU.
