Methods and systems for managing operation of data processing systems are disclosed. The data processing systems may include a limited number of hardware components. To increase the usable number or types of hardware components, an add-in card or other device may be attached to the data processing system. When connected to the data processing system, these devices may consume power delivered by the data processing system. The devices may cooperate with the host data processing system so that power is consumed in a manner that is less likely to negatively impact operation of the devices and host system.
