So in any of the Connectors from the PSU has a YELLOW Wire it will supply the  12 Volts at what ever Amps the Specs say RIGHT?

And this goes for the other Voltages


This is correct.

    Ok so if I see a PSU and it has ONE 24 pin connector for the Motherboard and a little 4. pin connector for extra power that goes next to the CPU. And it has a lot of connector for Hard Drives and CD ROM Drives  this is what I now need help with.

    Every connector has at most one YELLOW Wire in it and the YELLOW Wire is 12 Volts. So if I see the specs say -12V at 18A

    Then I know every connector with a YELLOW Wire in it will have 12V at 18A

    I know I know not everything will draw the full 18 Amps.

    But a lot of specs for PSU in one spec say
    -12V at 18A
    -12V at 30A

    So how do I know if the one that says 18A is not the YELLOW Wire in the Hard Drive connector   and the same goes for the 30A

    Thanks

    Hey Nymph, please sort yourself out.  You are going round in ever decreasing circles.

    You must be specific if you hope one day to reach A+.  Everything you have been given indicates that the Yellow cable is positive 12V (+12v) so why are you quoting negative 12V (-12V)???  The Blue cable is negative 12v (-12V).  On the ATX 20-pin Molex Main Power Cable (I already supplied a link to this) Pin 10 is colored Yellow for +12V, Pin 12 is colored Blue for -12V.  There's no point in showing 12V, you must show the polarity, + or -.

    What the heck are you asking ???   Have a look at the pretty technicolor pictures here again, the 4-pin Molex Peripheral Connector does NOT carry -12v at any pin. It has +12v DC, two gnds and one +5v DC, these are colored Yellow, Black, Black and Red (note - Yellow for +12v DC).  -12V will be carried on a BLUE cable, there is no Blue cable in a hard drive connecter.

    If you want sensible answers you must ask sensible questions and read the answers.

      OK OK I am sorry I did not ask in the right way.

      Like you told me every connector has at least one YELLOW wire.
      And the Yellow wire is rated 12 V

      When ever I look at specs for a PSU it says the Voltages for +5 and +3.3    but when it comes to the 12V it gives a couple.

      +12V at 18A
      _12V at 30A

      When it does this how do I know what Yellow wire will be giving the 30 Amps or the 18 Amps.

      Every connector has a Yellow wire in it.
      This is how I sould have asked it in the first place

        OK I just saw a PSU that says.
        +12V at 28A
        +12 at 28A
        +12V at 28A
        -12V at 0.6A

        OK this is what I ment all of these are +12 Volts but one is -12 Volts.
        Now if all Yellow Wires supply 12 Volts then how do you know what Yellow Wire is suppling the -12V at 0.6A

        This is it I sould have put it like this to start with.

        How many times must you be told, ALWAYS SHOW THE POLARITY.

        The Yellow cables carry +12V, YELLOW CABLES DO NOT CARRY -12V AT ANY AMPERAGE.   BLUE CABLES CARRY -12V.

        YELLOW CABLES CARRY +12V, THEY DO NOT CARRY -12V.
              BLUE CABLES CARRY -12V, THEY DO NOT CARRY +12V

        SO GET YOUR COLORS SORTED:
        YELLOW INDICATES +12V (PLUS 12V/POSITIVE POLARITY)
             BLUE  INDICATES -12V (MINUS 12V/NEGATIVE POLARITY)

        YELLOW CABLES DO NOT CARRY 12V
        YELLOW CABLES CARRY +12V (NOT 12V OR -12V BUT +12V)

        I challenge you to show where anyone has told you that every connector has at least one YELLOW wire and is rated 12V.  You are the one who posted that statement!!

        Sorry about shouting but geez, what does it take to get through ??? Grrrrrr!!

          AT P8 Connector has a Yellow Wire and Drive Connectors have a Yellow Wire and the 20 Pin Connector has a Yellow Wire in it.

          So all Power Connectors do have Yellow wires.

          But I do get it now when I see a PSU and it gives a fue diferant 12V at diferant Amps I have to look at what the + and or - is.

          And what ever the color Wire in that connector then that is what the Amps will be for that one.

          So we're now discussing AT power supplies?  I thought we were discussing ATX/ATX-2 psus as that's what you linked here..

          Have another look at this site which I linked in Reply #9 on 8th Oct.   Have you seen the 6-pin Aux Connector?  This is a power connector, does it have a yellow wire carrying +12v?  But then, that's available in an ATX psu, not an AT.

          Over and definitely out.

            OK I think I understand what you are telling me ATX PSUs and AT PSUs are diferant in how they have color wires.

            But I need help with this.

            Is an Auxiliary Power Connector 6. Pin for the CPU??
            I don't know if I ever seen them befor. The onnly ones I came across are the little 4. Pin sqware ones that plug into the CPU socket. 

            Each Pin is Rated 5. Amps at up to 250 Volts and the additionnal + 5. Volts Wire allows 29 Amps to be avialble to the Motherboard.

            Pin 1. = Black Wire Ground.
            Pin 2. =  Black Wire Ground.
            Pin 3. =  Black Wire Ground.
            Pin 4. = Orange Wire + 3.3 Volts.
            Pin 5. = Orange Wire + 3.3 Volts.
            Pin 6. = Red Wire + 5. Volts.

              no, it is for older motherboards that required more juice then what the main 20pin connector could provide. newer PSU's will not have this connector.

                I can't find this one Connector that commes from the PSU and I think it is just on ATX PSUs.

                It is a Very small Sqware connector like a littile box type of connector. And it goes RIGHT next to the CPU.

                This has to be for giving power to sertan CPUs but I don't know. Am I right about what this connector is for?

                  that depends, are you still talking about the six pin connector in your last post or are you talking about the socket on the motherboard next to the CPU?

                    I mean it is on the ATX PUs and it is a little Four Pin connector and it is sqware.

                    The connector goes right next to the CPU socket and I don't know what it's fore or what it's called????

                      it supplies power to the CPU. i just call it the CPU power plug.

                        And is the Color Code just as is with other wires of the same color??
