Understanding Your Computer’s Power Supply
The power supply is the heart of any computer system. It converts electricity from a wall outlet into a form that the computer components can safely use. Without a reliable power supply, a computer cannot function, and sensitive components like the motherboard, CPU, and storage devices could be damaged.
How Power Supplies Work
A power supply takes alternating current (AC) from your home or office outlet and converts it into direct current (DC) needed by computer components. Modern power supplies provide multiple output voltages, including 3.3V, 5V, and 12V, to ensure that every part receives the correct level of power. Efficient power supplies also include protections against overvoltage, short circuits, and overheating, keeping your system safe.
