How do I know which rails my mobo draws power from?

As the topic says... I wanna know which rails (12v, 5v etc.) are used for cpu, gpu, optical's, does anyone know that, or where I can look it up? thanks.

I honestly appriciate you attempt to help, but what you did in this case is the opposite. You spammed. You gave a link which I'm quit certain you didn't bother reading what is written there, 'cause then you would have known it has nothing to do with the simple question I asked. So again, I don't blame you, and I appriciate your help attempt, but next time please check that your post actually contributes. Thanks.

has a good breakdown... Or you can do a google search on a PSU calculator... Some will just spit out the total wattage.. others sometimes show the individual allocation used by the 3.3, 5 and 12v rails....

the link above does not show PCI Express .. which I believe is 12v.. sure others can chime in on this...
