What is the voltage delivered for disk drive motors in a computer power supply?

• A. 3.3 volts
• B. 5 volts
• C. 12 volts
• D. 24 volts

Answer: (C)

The voltage delivered for disk drive motors in a computer power supply is 12 volts. This voltage is specifically used for powering the motors found in hard drives and other disk drives, which require more energy to initiate and maintain the rotation of the platters. The 12-volt supply is essential for ensuring that these motors operate efficiently and reliably, as they must manage the varying loads during startup and normal operation. In contrast, other voltage levels provided by computer power supplies serve different components. For instance, 3.3 volts and 5 volts are typically used for powering logic circuits, memory, and lower-power devices within the computer. These components usually have less demanding power needs compared to the motors in disk drives. Understanding the specific voltage requirements is crucial for proper system functionality and hardware compatibility.
