How many Blue LEDS can you run of a single molex connection? and what resisters would you use ?

How many LED's off a single molex ?

This might be of help to you: http://led.linear1.org/led.wiz
The source voltage for a molex will be either 12v, 7v or 5v. Depending on how you wire up the molex to the LED array. The diode will probably be 3.3v and 20mA.

Apart from the need for resistors, LED's tend to be around the 30mA mark. Considering the PSU can supply many Amps, you dont need to worry about the quantity. Connect 2 Blue LED's in series to the 5V line, and then as many of these as you want in parallel.. That gives you 2.5V per LED and you can stick as many in as you like (in multiples of 2).
