A protection circuit includes a switch circuit, a sample circuit, a comparison circuit, and a relay circuit. The switch circuit is connected between a hard disk power supply and a hard disk to control whether to output power from the hard disk power supply to the hard disk. The sample circuit samples the voltage being supplied to the hard disk, the comparison circuit receives the sampled voltage, compares the sampled voltage to a reference voltage, and controls the switch circuit to be turned on or off accordingly. The relay circuit is connected between a system power supply and an enable terminal of the comparison circuit. The relay circuit outputs a high level signal to turn on the switch circuit when the system power supply is being supplied and the hard disk power supply is not being supplied to the hard disk.

A power supply device for a computer system with a plurality of servers includes a control unit, a main board, and a connection unit. The control unit includes a plurality of switches. The main board includes a power supply and a strobe circuit. When any one or more of the switches is turned on, each turned-on switch generates a control signal. The control signal causes the power supply to be turned on, and simultaneously causes the strobe circuit to generate a selection signal corresponding to the turned-on switch. The connection unit electrically connects the power supply to a server corresponding to the turned-on switch in response to reception of the selection signal from the strobe circuit by the connection unit.
