What is SATA and how does it relate to power supplies?
SATA (Serial Advanced Technology Attachment) is a type of interface used to connect devices such as hard drives, solid-state drives, and optical drives to a computer’s motherboard. It is a standard interface used for data transfer and power supply to these devices. In the context of power supplies, SATA cables are used to provide power to these devices.
In a typical setup, a SATA power connector from the power supply unit (PSU) is connected to the SATA device, providing the necessary power for its operation. The SATA power connector has 15 pins, with 3 pins dedicated to 3.3V power, 5 pins for 5V power, and 7 pins for 12V power. The power supply unit provides the necessary power to the device through these connectors, allowing it to function properly.
What are the different types of SATA power connectors?
There are several types of SATA power connectors, including the standard SATA power connector, SATA power connector with 3.3V auxiliary power, and SATA Express power connector.
