The power supply also provides power to the computer's components, including the processor, memory, and storage. While the power supply is a vital part of an iMac computer, it is not the only component that is responsible for the computer's power needs. The processor, memory, and storage also play a role in the power needs of an iMac computer. The processor is responsible for processing information and data, and the memory stores data and information. The storage holds data and information that is not being used by the processor or memory.
