A cheaper PSU can feel fine at the start, so the capacitor question is easy to ignore. The problem shows up later, especially if the case runs warm or the GPU pulls hard during long sessions. I had one older unit that became less stable after a couple of years, and that made me pay more attention to internal quality. When researching
PSU Lifespan, I liked the explanation that capacitors are not just marketing words; they affect voltage stability, heat tolerance, and how the unit ages. I would not buy only because a box says “premium,” but I would check what components are actually used. For a gaming PC kept for years, better capacitors can be worth paying for.
