PSU — Power Supply Unit
📖 What is it?
The PSU converts AC power from the wall into DC power that PC components use. Wattage and efficiency rating are key specs.
⚙️ How it works
PSUs use transformers and voltage regulators to provide stable 3.3V, 5V, and 12V power rails to components.
🗂️ Types
- ATX (standard)
- SFX (small form factor)
- Modular (detachable cables)
- Non-modular (fixed cables)
