The Power Supply Unit
The power supply unit supplies power to all the hardware components. This ensures they receive a steady and reliable flow of electricity. A high-quality PSU is essential for handling the power demands of powerful gaming CPUs, graphics cards, and other peripherals, preventing issues like voltage fluctuations and power surges that could damage the hardware. Additionally, an efficient PSU reduces wasted energy and heat generation, contributing to a cooler and more energy-efficient gaming PC.
