Which of the following voltage levels is typically provided by a computer power supply?

• A. 1.5 volts
• B. 3.3 volts
• C. 24 volts
• D. 48 volts

Answer: (B)

A computer power supply commonly provides a voltage level of 3.3 volts, among other voltages. This specific level is essential for powering various components of a computer, particularly for the logic circuits and memory modules, which require stable lower voltage inputs to operate efficiently. In a typical ATX power supply, you'll often find different voltage outputs: 3.3 volts, 5 volts, and 12 volts, catering to the needs of the motherboard, storage devices, and other peripherals. The 3.3-volt supply ensures that the digital circuits function properly, which is fundamental in modern computing technology where integration and efficiency are key. The other voltage levels mentioned serve different applications or devices. For instance, 1.5 volts is frequently used in battery applications rather than in computer power supplies. Likewise, 24 volts and 48 volts are more common in industrial applications or specialized equipment rather than typical consumer computing hardware.
