A time sequence control circuit is provided to control time sequence of a motherboard of a computer. A first voltage received by a power supply receiving terminal is greater than a preset voltage before a signal control terminal on the motherboard receives a second voltage during turning on the computer. During shutting off the computer, the first voltage at the power supply receiving terminal drops and is less than the preset voltage, and the second voltage supplied to the signal control terminal on the motherboard is shut off.

Time sequence control circuit

A power control circuit for a hard disk drive (HDD) includes a first control circuit, a second control circuit, a first connector connected to a power supply, the first and second control circuits, and a second connector connected to the first control circuit and the HDD. The power supply outputs a first voltage signal and a second voltage signal to the first and second control circuits via the first connector. The first control circuit converts the first and second voltage signals into a form compatible with a timing sequence of the HDD receiving voltage signals, and outputs the first and second voltage signals to the HDD via the second connector. The second control circuit controls the first control circuit.
