Controlling power consumption at an IHS, including receiving electrical power associated with an initial voltage at a first time; determining that the IHS is to enter a low-power state, and in response: adjusting an UVP parameter for the electrical power from a first voltage to a second voltage, the second voltage less than the first voltage, the second voltage based on the low-power state; adjusting an OCP parameter for the electrical power from a first amperage to a second amperage, the second amperage less than the first amperage, the second amperage based on the low-power state; trimming the initial voltage of the electrical power to a trimmed voltage, the trimmed voltage less the initial voltage and greater than the second voltage; adjusting the power state of the IHS to the low-power state; receiving the electrical power having the trimmed voltage at a second time after the first time.
