A power reset circuit with zero standby current consumption includes a power storage unit, first, second, and third voltage detection units, a switching unit, and a power reset unit. The power storage unit stores electric power by a supply voltage source. The first, second, and third voltage detection units are connected to the supply voltage source to start a switching circuit of the first, second, and third voltage detection units in accordance with a change in a normal supply stage, a shutdown stage, and a voltage ramp-up stage of the supply voltage source, control a voltage level of the power reset unit, and thereby generate the power reset signal. Accordingly, the power reset circuit does not consume current in a standby state (the normal supply stage of the supply voltage source) and thus is characterized by zero current consumption.
