- Converts wall AC power to low-voltage DC power.
- Wattage matters (e.g., 500W, 750W).
- 80 Plus rating = efficiency.

- Cores: Multiple “mini-CPUs” inside one chip (e.g., 4, 6, 8 cores).
- Threads: Virtual cores for multitasking.
- Clock Speed (GHz): How fast each core works (e.g., 3.5 GHz).
- ROM (Read-Only Memory): Non-volatile memory used to store the startup instructions (BIOS/Firmware). Data remains even without power.
