When I was dealing with the same problem, I realized that PSU choice is more about balance than raw power https://seasonic.com/insights/seasonic-psu-best-suited-for-cooling-system-and-case-size/ breaks down how power supply dimensions, case formats, and cooling setups all work together. It helped me understand why a long PSU in a compact case can block airflow or complicate cable management. After applying that advice, my build ran quieter and cooler than expected. Instead of guessing or copying random builds, it’s smarter to match the PSU to the case layout and cooling plan. That approach saves money and avoids headaches later.
