The power button goes to the MB, not the power supply, and starts the sequence, when you have it set for manual on/off. Most BIOS'es can be set for either last power status or always come on after power restoration. I have mine set this way, as I turn the whole machine on from a power strip.
So, anyway, the PS has to turn the CPU on so the BIOS can look to see what its power-on response is set for. And this is real nice, as a remote server you want to power up whenever power is restored after an interruption.
