Abstract
A power circuit for different types of fans includes first through sixth terminals, a control chip, first through third loads, and a connector. If a 3-pin fan is connected to the connector, only the first load connects the first and second terminals, and a control pin of the connector is idle. If a 4-pin fan is connected to the connector, the second load connects the third and fourth terminals, the third load connects the fifth and sixth terminals, and the first load does not connect the first and second terminals. The control pin receives a divided voltage to control fan speed.
