A power switch device and method for a cluster computer is described. A power input circuit receives plural input powers and plural state signals corresponding to the input powers. A first output circuit supplies the input powers to a head node and at least one compute node. A second output circuit supplies the input powers to the head node. A gate produces a switch signal according to the state signals. According to the switch signal, a switch module connects the power input circuit to the first output circuit or the second output circuit. And a spare power module, connected to the first and second output circuits, stores a spare power charged from the first output circuit and supplies the spare power to the second output circuit during a switch period.
