"Got some noise from my PSU when i load games with high fps. Its a corsair 650TX. I have replaced the PSU with three diffrent brands, but the noise did not go away... i am confused, the noise clearly comes from the PSU.

That his system sounds like a locomotive is an another issue. It's the very high pitched sound that is almost exactly like mine.
Some of what he writes is gibberish.. but that he had 3 different PSU's in his system that did the same thing, makes me worry that it actually has something to do with my new system
