A computer-implemented method for adjusting voltage settings, according to one embodiment, includes: determining a number of components electrically coupled to an output of a voltage regulator; determining voltage tolerance information corresponding to each of the number of components; determining a voltage tolerance limit of the voltage regulator; using the determined voltage tolerance information in combination with the voltage tolerance limit of the voltage regulator to determine whether an output voltage of the voltage regulator can be reduced; calculating an amount by which to reduce an output voltage of the voltage regulator in response to determining that the output voltage of the voltage regulator can be reduced; and sending one or more instructions to the voltage regulator to reduce the output voltage of the voltage regulator by the calculated amount.
