Question
Answer and Explanation
Baseboard Management Controllers (BMCs) typically use a low-voltage DC power supply. The specific voltage varies depending on the hardware design but common voltages are 3.3V or 5V. The BMC consumes very little power compared to the main CPU or other components of the server, its power needs are usually quite low and are often supplied through the motherboard or a dedicated power rail.
BMCs are designed for efficiency, as they need to remain operational even when the primary system is powered off. This allows them to perform tasks like remote management, system monitoring, and power control. The power consumption is usually in the range of a few watts or even less, ensuring minimal impact on overall energy use. Different BMC chips and vendors may have slightly varying power requirements.
