A Power Supply is one of the most essential components of any computer system. It converts electricity from your wall outlet into usable power for internal components such as the motherboard, processor, storage devices, and graphics card. Without a reliable power supply, even the most advanced hardware cannot function properly.

How a Power Supply Works

The primary job of a power supply is to regulate voltage. Household electricity is far too strong and inconsistent for sensitive computer hardware. A Power Supply transforms this energy into stable, low-voltage output and distributes it safely across the system. This regulation helps prevent damage caused by power spikes, fluctuations, or electrical noise.
