    I've seen a few terms briefly explained in this thread, but not much about the 3.3v, 5's etc.

    Is each voltage, 3.3v, 5v, 12, it's own "rail"?
    Is the different rails for specific tasks? I think the 12 is for CPU's and video cards, but not sure about the rest. And what about "Rippling".

    Thanks in advance.
