Abstract: A connector assembly includes a first connector, a second connector, a first controller, an inter-integrated circuit (I2C), and a second controller. The first connector is electrically connected between a first element and the first controller. The second connector is electrically connected between a second element and the second controller. The I2C is electrically connected between the first controller and the second controller. The first connector receives and outputs a number of parallel signals from the first element. The first controller converts the parallel signals into two serial signals. The I2C transmits the two serial signals to the second controller. The second controller converts the two serial signals into a number of parallel signals.

Abstract: A computer includes a number of hard disk drives (HDDs), a number of Serial Advanced Technology Attachment (SATA) connectors correspondingly connected to the HDDs, and a number of jumpers. Each SATA connector includes a power supply pin, a spin-up pin, a ground pin, and a pin base with first to third pins. The first to the third pins are respectively connected to the power supply pin, the spin-up pin, and the ground pin. The second pin of each SATA connector is connected to either the first pin or the third pin by a corresponding jumper, thereby the corresponding HDD starts up with the computer or starts up at a preset time after the computer has started up.

Abstract: A voltage adjustment circuit for a storage medium includes a storage medium interface, a storage medium control chip, and a switch module. When the storage medium is read or written to by the storage medium control chip, the storage medium control chip transmits a pair of differential signals to the storage medium interface so that the switch module can control a power supply to power the storage medium. And the switch module will control the power supply not to power the storage medium when the storage medium control chip does not operate to read or write the storage medium.
