Default High Pitched Screech from PSU on first boot

Greetings: I just completed my build, and upon first boot, I'm hearing a loud screen from the PSU.

I stayed up finishing this build last night, and I am really worried that I did something wrong. When I boot up, the fans all spin up with their LEDs, so there is at least some power being supplied to the machine. I wish I knew where I went wrong, and what I can do to save my new machine!

PSU might be dying. Bad one in the crowd. Can you describe the pitch? It is just screeching?

The pitch is loud but not painful to the ears. When I kill the power, it gets slightly louder than it ever was, and slowly fades out over a period of 3 seconds.

I don't think that would cause a high pitch sound. Its the inside of the fan thats bad.

The sound seems electrical in nature. It doesn't sound like a system speaker beep, but it is comprable to that in nature - just not in pitch. It does not sound like rubbing, grating, or anything like that.
