    I've just worked out my LED's I need and have worked out how I'm going to wire it up.

    Could someone just check I have it right and check I have the right resistors.

    all these LED's are off lsdiodes

    1. Wired in series 2x 5mm blue LEDs. With 1x 270ohm resistor

    2. 2x 5mm blue 2x 5mm orange in parallel
    for the blue I'm going to use 470ohm
    for the orange I'm going to use 560ohm

    3. 1xblue and 1x orange in parrellel
    blue I'm going to use 470ohm
    orange I'm going to use 560ohm

    4. 3xblue and 3xorange
    blue I'm going to use 470ohm
    orange I'm going to use 560ohm

    all these LED aren't going to put to much pressure on my PSU are they?

    How do I wire them to the molex?

    Thanks in advance

    1. Correct value
    Code:
    +12v- -/\/\/- -|>|--|>|- -GND
    
    2. 330ohm for oranges, 220 for blues.
    Code:
    -|>|-  -|<|-
    -|>|-  -|<|-
    <   |  |   <
    >  GND--   >
    <          <
    >          >
    |          |
    +12v - - - -
    
    3. Correct values
    Code:
    +12v - -
         < <
         > >
         < <
         | |
         - -
         V V
         - -
         | |
    GND  - -
    
    4. 200ohm for orange, 150 for blue.
    Just repeat the schem from #2, but add another LED on top.

    No, these won't stress your power supply. If you did all of these, then the amount current drawn by all 14 LEDs wouldn't equal the amount that a cold cathode inverter draws. Not to mention your drives motors take a hell of a lot more than that.

    kool thanks alot for sorting that out for me.

    although I don't quite get the Code: bits

    I get what your trying to show but don't know what bit is what

    Well, it makes since to me since I've spent quite a bit of time looking at schematics.

    Resistor: /\/\/
    LED: -|>|- (technically it's only for a diode, an LED has little arrows pointing away from the diode, but I can't exactly recreate those with a keyboard)
    +12v and GND come from your Molex. +12v is yellow, GND is black (either black will work).
