Matthew, your post is very thorough and well-organized. I like how you broke down PSU troubleshooting into clear, step-by-step techniques that cover both basic and advanced diagnostics. Your inclusion of visual inspections, POST checks, and testing with a multimeter shows a solid understanding of practical troubleshooting methods. The paperclip test and swapping with a different PSU are especially helpful for quickly isolating whether the PSU itself is at fault. I also appreciate that you considered factors like capacitor aging, cooling, and short circuits, which are often overlooked but can cause intermittent issues. Overall, your explanation makes it easy for someone to follow a logical troubleshooting process and ensures that power-related problems are diagnosed systematically. This kind of methodical approach is exactly what IT professionals need when maintaining reliable systems.
