I just bought a new XClio 450BL 450W PSU which is great so far with one exception: it emits a high pitched whine whenever the computer is turned on. Based on other threads I found in searches on the forums, it sounds like it's high load on the PSU that causes the problem.
Here's the catch though: I upgraded from an old Antec True430 PSU that has less wattage overall as well as less power on each rail and the Antec didn't whine. The Antec had a total of 26A on the +12v rail and the XClio has 15A and 17A respectively which is quite a bit more. Is it possible I'm overloading a single +12v rail and that's what's causing the problem?
As I understand it, the power supply should be more than enough for my particular system - I'm not overclocking at all. Specs are listed below and any and all help and suggestions would be appreciated.
