A power diagnostic system and method for detecting faults is provided. The system includes a processor coupled to a plurality of sampling blocks; wherein the plurality of sampling blocks simultaneously perform current measurements and voltage measurements at a plurality of loads, based on a reference signal generated by a clock generator; wherein the sampling blocks measurements are sent to the processor via power cables that are also used to supply power to the plurality of loads. The method includes sampling currents and voltages at a power supply and at a plurality of loads; wherein the sampling is synchronized to a reference signal; transmitting sampled currents and voltages to a processor; comparing sampled currents and voltages with threshold values; and identifying faults if the sampled currents and voltages vary from the threshold values.
