In accordance with embodiments of the present disclosure, a power supply unit may comprise a plurality of output terminals configured to supply electrical energy to one or more information handling resources, a measurement module configured to measure one or more parameters indicative of an intermediate impedance between the power supply unit and at least one other power supply unit, and a microcontroller unit. The microcontroller unit may be configured to estimate an intermediate impedance based on the one or more parameters and communicate the intermediate impedance to a controller of an information handling system in which the power supply unit is disposed.
