Claim:
1. A computer-implementable method of budgeting power allocation for an information handling system, the computer-implementable method comprising: in response to determining that the information handling system is to be powered by a redundant configuration of multiple PSUs having a primary PSU in redundant configuration with a secondary PSU: calculating a power budget, based on discovery of installed system components, of a thermal design power (TDP) of the system that is a first amount of power required for the system that is less than a maximum amount of power that can be consumed by the system during periodic power transients; and configuring the system to be powered using the TDP during normal operation and to autonomously utilize unused operating margin of the redundant configuration of the PSUs during periods in which the system requires greater than the first amount of power, wherein the system is configured to draw, from the redundant configuration of multiple PSUs, a maximum power equal to the TDP plus a maximum value of all of the power transients, wherein the maximum power exceeds one hundred percent of a total power capacity of a single one of the primary PSU and the secondary PSU by utilizing a portion of total available power capacity from the combination of the primary PSU and the secondary PSU; wherein the TDP of the system does not exceed the output of the primary PSU within the redundant configuration; in response to determining that the information handling system is not to be, or no longer, powered by a redundant configuration of multiple PSUs, calculating a power budget, based on discovery of installed system components, of a second amount of power for the system that is at least equal to the maximum power that can be consumed by the system, and which does not exceed the output of the primary PSU; and in response to a total amount of current system power required being above the first amount of power budgeted, automatically allocating unused operating margins of reserve power from the redundant configuration of the PSUs in order to support system operation within a power envelope that accounts for the power transients by extending the power envelope to include the power transients, wherein the maximum power consumed during the power transients can be greater than a total power capacity of the primary PSU, while the IHS is operating in the redundant configuration of PSUs.
