1. A protection circuit applicable in a server system, the server system comprising a mainboard circuit, the protecting circuit comprising:
at least two power sources;
a comparing module configured to determine whether the at least two power sources are the same; and
a protecting module, the protecting module and the comparing module being electrically connected between the at least two power sources and the mainboard circuit,
wherein when the at least two power sources are the same is determined, the comparing module outputs a first signal, the protecting module connects the at least two power sources to the mainboard circuit according to the first signal; and
when the at least two power sources are not the same is determined, the comparing module outputs a second signal, the protecting module disconnects the at least two power sources from the mainboard circuit according to the second signal;
the at least two power sources are configured to provide power for the server system and comprise a first power source and a second power source, the first power source outputs a first current and a first voltage, the second power source outputs a second current and a second voltage;
the comparing module comprises a comparator electrically connected to the first power source and the second power source, the comparator receives the first current, the first voltage, the second current, and the second voltage, the comparator compares whether the first current is equal to the second current, and compares whether the first voltage is equal to the second voltage, so as to determine whether the first power source and the second power source are the same.
