The invention provides a power-on circuit, a battery backup unit and a storage server system.The power-on circuit comprises an activation circuit and a delay circuit, the first end of a first controlled switch of the activation circuit is connected with the anode of a first diode, and the cathode of the first diode is connected with a control terminal, corresponding to a charging circuit, of the battery backup unit; one end of a first resistor of the delay circuit is connected with the second end of a first controlled switch, the other end of the first resistor is connected with the control terminal of the first controlled switch and one end of a capacitor, and the other end of the capacitor is connected with the first end of the first controlled switch and then grounded. And when the battery backup unit is inserted into the target object, the second end of the first controlled switch is connected with the charging power supply corresponding to the battery backup unit. Therefore, activation of the battery bac
