About two years ago I bought a Corsair TX650W power supply. A little overkill for the work I’m doing on that computer, but since it’s a decent brand, I thought I’d go for a quality product. After limited time I have used this desktop, when I power on the PSU, I get a smell of burning plastic. Because Corsair has a limited warranty of 5 years, I’m hoping they will replace the PSU asap. Will get back to you to see how this story works out.
