Functions of a Power Supply Unit (PSU) in a Computer:
1. Conversion:
- Converts alternating current (AC) power from the wall outlet to direct current (DC) power required by computer components.
2. Voltage Regulation:
- Provides stable and regulated DC voltage levels (+3.3V, +5V, +12V, etc.) to power components and prevent voltage fluctuations.
3. Current Delivery:
- Supplies sufficient current (amperage) to meet the power demands of connected components, ensuring stable operation.
4. Protection:
- Protects the computer from electrical damage by providing:
- Overvoltage protection: Prevents excessive voltage from entering the system.
- Overcurrent protection: Limits current flow to prevent damage to components.
- Short circuit protection: Detects and interrupts short circuits to minimize damage.
- Overheat protection: Shuts down the PSU if it overheats to prevent fire or damage.
5. Fan Cooling:
- Includes cooling fans to dissipate heat generated during power conversion and protect the unit from overheating.
6. Form Factor and Connectivity:
- Comes in various form factors (ATX, SFX, etc.) to fit different computer cases.
- Provides connectors (e.g., 24-pin, 8-pin) to connect to the motherboard, graphics card, hard drives, and other components.
7. Efficiency:
- Measured by the "80 Plus" rating (e.g., 80 Plus Gold), which indicates the efficiency of converting AC to DC power. Higher efficiency means less power loss and lower energy consumption.
8. Power Capacity:
- Rated in wattage (e.g., 500W, 850W), indicating the maximum amount of power it can deliver to components. Choosing the appropriate power capacity ensures adequate power for stable operation.
