Power Supply

A PSU (Power Supply Unit) is the component in a computer that takes electricity from a wall outlet and converts it into the right type of power to run the computer's parts. It supplies power to the motherboard, CPU, graphics card, hard drives, and other components, making sure each part gets the correct amount of voltage to work safely and efficiently. Power conversion: The PSU converts the high-voltage electricity from the wall into lower, stable voltages (like 12V, 5V, and 3.3V) that the computer components need. Power distribution: It then distributes power through various connectors to different parts of the computer, ensuring each gets the power it requires. Wattage: PSUs come in different power capacities (measured in watts), so more powerful computers with high-performance parts (like strong graphics cards) need higher-wattage PSUs. Modular PSU Removable cables: A modular PSU lets you attach only the cables you need, leaving out unnecessary ones. This makes cable management easier, keeps the case tidier, and improves airflow. Flexibility and convenience: Modular PSUs are great for custom builds since they help reduce clutter, allowing for a cleaner-looking system and better cooling. Non-Modular PSU Fixed cables: In a non-modular PSU, all the power cables are permanently attached to the unit. This means you have to find a place for unused cables inside the case, which can lead to more clutter and restrict airflow. Lower cost: Non-modular PSUs are generally less expensive because they're simpler to manufacture and don't have the extra connectors or design features of modular PSUs. Why Some PSUs Are More Expensive? Modularity: Fully modular PSUs are generally more expensive than non-modular or semi-modular ones. Power capacity: Higher wattage PSUs (750W, 850W, 1000W+) are pricier due to the increased power output they offer for high-performance or multi-component systems. Efficiency rating: PSUs with higher efficiency ratings (like 80 Plus Gold, Platinum, or Titanium) cost more because they waste less energy, produce less heat, and are often built with higher-quality components. Quality and reliability: Premium PSUs use durable components and have protective features (like over-voltage, over-current, and short-circuit protection), which adds to the cost but ensures longer lifespan and better stability.
