Power Supply
A power supply is a hardware component that converts electrical power from a source (such as a wall outlet or battery) into the correct voltage, current, and frequency required to operate electronic devices, including computers and other IT equipment. It ensures stable and reliable power delivery to prevent damage and ensure optimal performance of connected components.
Developers should understand power supplies when building, maintaining, or troubleshooting hardware systems, such as desktop computers, servers, or embedded devices, to ensure compatibility, efficiency, and safety. Knowledge is crucial for tasks like selecting appropriate wattage for high-performance GPUs in gaming or AI workstations, or ensuring uninterrupted power in data centers to prevent data loss.
