And you realize: the question was never “how to tell power supply wattage.” The question was “how to stop lying to yourself about what you need.”
You start digging. Not into your PC, but into the arithmetic of your own mistakes. The CPU: 95W under load. The GPU: 220W peak. Motherboard, RAM, drives, fans, USB devices—add another 80W.
