and configuration interface acpi specification the control states may be ranked in an order depending on how much power consumption is required the controller 101 may receive for example commands from other system controllers or processors that cause controller 101 to increase its control state and thereby the power consumed by transient load 102 the increase in power consumed by transient load 102 may comprise a transient event voltage regulator 103 may receive power from a power supply and provide dc regulated power to the transient load 102 through connection 105 the dc regulated power may be limited to a specific dc voltage depending on the load for example the dc voltage may be 1 5v for dimms and 3 5v for pcie storage when a transient event occurs in transient load 102 the voltage regulator must change current output to accommodate the increased or decreased power requirements of the transient load existing vrs change output power only after the control state has been changed and the transient event has occurred leading to a severe drop in dc voltage and a high undershoot u2014 the drop in dc voltage from the steady state dc voltage output of the vr following a transient event according to aspects of the present invention controller 101 may include a transient load engine 106 that outputs a transient notification.
