I just recently finished a new computer build for $280, or so I thought. I did it reluctantly. I was hoping to hold on to my old Core2Duo I built back in 2007 until 2022 when they stopped supporting Windows 8. In fact, I probably would have pushed it even until they stopped supporting Windows 10 with the free upgrade However, while I'm able to milk all my other components for all they're worth, my PSU's always seem to give out on me every 2-3 years. The last one supposedly shorted out my motherboard when it took a dive which is why I had to assemble a new build. Now my new build is making a high pitched-whine from the PSU. I don't even have to turn the computer on, it just sits there and whines turned off. I have to turn the PSU itself off to stop the noise. So I had to order a new $40 Corsair which pushed my new build over $300. That made me furious I know the PSU is a mini-transformer and, as such, seems to be more prone to failure than perhaps most of the other components of the build, but what is it actually that keeps failing? What is the limiting factor? I read that the high pitched squeal that typically signals the death throws of a power supply unit are burned-out capacitors. Is this right?
