From my experience, a power supply is one of those parts you shouldn’t cheap out on, even if it’s not the most exciting component. A good PSU protects all the other hardware and keeps everything running smoothly under load. I usually look at brand reputation, certifications, and real user feedback instead of ads. It also helps to check official product lines and explanations directly from the manufacturer, like https://seasonic.com/power-supplies/, because you can clearly see how different series are meant for different builds. Once you understand your system’s needs, choosing becomes much easier and less stressful.
