Here's why:
* The CPU's Function: The CPU is the "brain" of your computer. It processes instructions and performs calculations.
* The Power Supply's Function: The power supply is responsible for converting the AC power from your wall outlet into the DC power that the CPU (and other components) need to operate.
Think of it like this:
* The CPU is like your brain: It does all the thinking and processing.
* The power supply is like the power plant: It provides the electricity your brain needs to function.
They work together, but they are separate components.
