I am using an old pc power supply to power some leds and a fan. I know about shorting the green pin with the black one, but I was wondering about the leds. LED's only work with the current in one direction (as they are diodes). How do I connect them to a molex connector?
I followed a link in one of my other threads and used the wizard. I got this:
Solution 0: 4 x 2 array uses 8 LEDs exactly

The wizard says: In solution 0:
each 68 ohm resistor dissipates 61.2 mW
the wizard thinks 1/4W resistors are fine for your application
together, all resistors dissipate 122.4 mW
together, the diodes dissipate 600 mW
total power dissipated by the array is 722.4 mW
the array draws current of 60 mA from the source.
I take it that I connect the left side of the diagram to the yellow wire, and the right side to the black wire next to the yellow?
