What You Should Know About ATX Power Supplies
ATX power supplies are essential components in modern desktop computers, converting alternating current (AC) from the wall outlet into the direct current (DC) required by computer components. Known for their reliability and efficiency, these power supplies come in various wattages and configurations to meet different system requirements. Understanding their features can help you choose the right model for your setup.
How do ATX power supplies work?
ATX power supplies function by converting AC electricity into regulated DC voltage through a series of internal components, including transformers and rectifiers. When plugged into an electrical outlet, the PSU provides multiple voltage outputs (typically +3.3V, +5V, and +12V) to power various computer components. The PSU also includes protection features to prevent damage from overvoltage or short circuits.
| Component | Function |
|---|---|
| Transformer | Converts AC voltage to lower DC voltage |
| Rectifier | Converts AC to DC |
| Voltage Regulator | Ensures stable output voltages |
