  • SPLIT: Question about rails

    One thing I dont get, is like in the package deal on the Carpc site. http://store.mp3car.com/Mp3Car_Custo..._p/ccc-122.htm

    That computers processor takes 25w of power, however the supplied Psu is the M1-atx, which has 24watts on the 12v rail(Btw im a newb with all this power mumbo-jumbo) so I hope i'm on the right track here.

    My question is... is according to the equation A x V = Watts, I would be asking for more power then I can draw, why would they sell you a system that wont work?

    maybe the cpu gets its power from the 5v not the 12v of the m1.............

      Okay again i'm somewhat new with the "rails". How do I know this? When is one used over the other? I'll look in the forum after I post this too just to double check that i'm not missing an important thread. I thought the 5v was for Standby or something and the 12 for the Psu

        5v standby and 5v are two different rails....

        also which rail your cpu uses depends more on MB manufacturer than cpu producer.

        of course such important info is never in the mb manual........

          So i'm looking at the manual, im guessing the "+3.3" and same with the 5v and 12v is the rail? Because it gives wattages, voltages, and amperage for each rail for different instances. One for playing mp3's, one for dvds etc. It doesn't say "This mb uses this rail to power cpu"...

            I think i'm understanding that rails=wires right? I'll move my questions over to the Newb forum area so I dont hi-jack this for more intelligent questions. Anyways thanks for your input

              No. A rail is more of an abstract concept.
              It's simply one of the output voltages of a PC's power supply. there is not really a physical manifestation of the rails.

              ANd quit cluttering up the FAQs.
              Have you looked in the FAQ yet?
              How about the Wiki?

                  Yeah. I saw the other post after I split this off from the FAQ.

                  Is the subject any clearer now?

                    Well as such the content of the subject hasn't changed, it isn't going to be any clearer since the last time you said anything about it
