Abstract: The technology is generally directed to a power throttling mechanism controlled by a payload receiving power provided by a rack, or other such power source. The power level provided by the rack may be maintained for a predetermined period of time. The power throttling mechanism may include the payload determining the predetermined period of time and a throttling offset. The payload may execute the power throttling by adjusting a voltage reference based on the throttling offset, after which the payload may maintain power usage for at least the predetermined period of time. According to some examples, in addition to throttling power for a payload, power capping may occur at substantially the same time. A power capping mechanism may transmit a notification to a controller, such as a baseboard management controller, to cap the power consumption of the datacenter.
