A power supply is an essential component that converts and regulates power from an electrical outlet into a format suitable for a computer's components. It ensures optimal performance, energy efficiency, and component protection by providing the required voltage and current to various parts of the system.
Consider factors such as wattage capacity, form factor, efficiency level, and additional features when choosing a power supply. Wattage capacity determines how much power the PSU can deliver to the system, while form factor refers to its physical size and shape. Efficiency level affects energy usage and waste heat, and additional features may include modular cabling or built-in fan control.
Power supplies come in various wattage capacities, ranging from entry-level 200W to high-performance 1500W+ models. Choose a power supply that meets your system's current requirements and can accommodate future upgrades.
Modular power supplies offer detachable cables, making cable management easier and allowing for customization. Non-modular power supplies have permanently attached cables, which may limit flexibility but can be more cost-effective.
ATX form factor is larger and offers more expansion slots, while SFX form factor is smaller and designed for compact systems. Ensure compatibility with your computer case before selecting a power supply.
High-efficiency power supplies waste less energy as heat, improving energy savings and reducing carbon footprint. Look for 80 PLUS certifications, such as Bronze, Silver, Gold, Platinum, or Titanium, to ensure a minimum level of efficiency.

Power supplies typically last for 5-7 years or more under normal usage. However, factors such as heavy use, overclocking, or environmental conditions may affect their lifespan. Regularly monitoring temperature and voltage levels can help identify potential issues before they cause system instability.
