Abstract

A protection circuit against connection of an incorrect power supply, applied in a server system, includes a mainboard circuit, the protecting circuit includes at least two power sources, a comparing module, and a protecting module. The comparing module determines whether the multiple power sources are the same in current and voltage. When the power sources are determined to be the same, the comparing module outputs a first signal, the protecting module connects the at least two power sources to the mainboard circuit accordingly. If the at least two power sources are determined as not being the same, the comparing module outputs a second signal, the protecting module disconnects the multiple power sources and the mainboard circuit accordingly.
