Answer:
C. 30% more.
Explanation:
The computer system is an electronic device and so it requires a certain level of power supply. Its hardware components are circuitry of electronic and electrical components or devices. They all need a certain voltage requirement to function properly.
The processor is the main hardware component on the motherboard, that controls the activities of all other components. It draws power from the power supply and sends signal, based on the power requirement of that component.
At the highest peak of operation, the supply overheats as it's power limit is used for a long time. And when the power supply diminishes over time, the supply would not be able to supply the needed power.
So a power supply of 30 percent over peak voltage is recommended to tackle these problems.
