How quiet is the Seasonic s12g 550w?

[brianthefish]

Under load, how audible is it? Also, compared to a corsair cx500, is it quieter or any better?

The Seasonic is much higher quality than the CX, I would not even consider the CX if I could buy the Seasonic.
For the noise they say here at 80% load it was still quite if your going to be loading it higher than that you need a bigger power supply anyhow.
