Whether you are building a new rig, troubleshooting random shutdowns, or simply curious about your machine's capabilities, knowing how to see power supply details on pc systems is an essential skill. But the power supply converts electricity from your wall outlet into stable, usable power for the motherboard, CPU, GPU, storage drives, and every other internal component. In this guide, you will learn multiple methods to identify, check, and interpret your computer's power supply, from physical inspection to software-based diagnostics.

- Wattage: The total power output, such as 500W, 650W, or 850W.
