US 12,596,419 B2 · Computer host and power control method thereof

Abstract

A computer host is provided, including a motherboard and a power supply. The power supply is adapted to supply power to the motherboard through a first power line and supply power to a graphics card through a second power line, and includes a rectifying element and a feedback control unit. The rectifying element controls the power supply to generate output power according to a feedback signal. The feedback control unit includes a first feedback input end and a second feedback input end, where the first feedback input end is adapted to be electrically coupled to the first power line to receive a first detection voltage, and the second feedback input end is adapted to be electrically coupled to the second power line to receive a second detection voltage. The feedback control unit selectively generates, according to an electrical coupling state between the power supply and the graphics card, the feedback signal according to the first detection voltage or the second detection voltage.
