If using prewired Molex then 12v and 5V is correct.
19V will burn out some components.
go to BIOS to check CDROM is present and jumpered correctly on drive if using ribbon cable.
Molex is a connector company that make 10k different connectors.
But when consumers say Molex conn. they usually mean the 4 pin conn type inside pc's.

...I mean i am using as a standalone CD Drive without pc....
I'm not sure what the issue is here, as it is quite straight forward.
Simply connect +12v to the yellow lead, +5V to the red lead, and GND to the remaining two black leads.
If you are using a standard PC AT/ATX power supply, the above should be sufficient or in this case use your adapter to connect to an existing four conductor female connector from the AT/ATX power supply to power your CD/DVD.
However, if you are using separate +12v and +5v power supplies, you should also ensure both the +12v and +5v power supplies share a common GND or black leads.

Update: Specifically, what type and current rated power supply are you attempting to use? Typically, internal CD/DVD drives are spec'd for power requirements in the +5V @ 1.5A, +12V @ 1.5A, range, so if you attempting to power your CD/DVD drive with a el cheapo wall wart, your wasting your time.
The black wires are both ground and internally joined in the drive. They are there to ensure the ground connection is a good one, using two wires instead of one is better electrically and mechanically.
For the two supplies, connect the +5V supply output to the +5V input on the drive and the 0V from the 5V supply to one of the grounds on the drive.
Connect the +12V supply output to the +12V input on the drive and the 0v from the 12V supply to the other ground on the drive.
Linking the grounds elsewhere will not cause any electrical problems but if you are using the drive for audio, it is possible you may introduce unintended paths for interference to travel through. For example, you might find that adding an extra ground connection produces a hum on the sound or a whining noise from the motor in the drive.
May I ask what the drive is intended to do? Without a connection to the SATA/IDE interface you are very limited to what you can use it for.

@brain : sorry ..did not follow... 0V from the 5V supply to one of the grounds on the drive.
I know i have some limitation in using it ...but still trying to see if i can work with it..
Unless you specify CD model or show input options, we can only guess
These are the most common interface cables.
Your 6 wire gives 2 options. 12V only (red) or 12,0,0,5 on 4 pin std Molex with 12 on Yellow wire.
You dont need both connectors.

The 2 wire 3 pin conn is intended for case fans
Funny how people get my name wrong every time!@brain : sorry ..did not follow... 0V from the 5V supply to one of the grounds on the drive.
Can you elaborate on what exactly the intended function is of this "Standalone CD Drive?"
I think the intention here is to make a homemade in car CD player, probably patched into the aux input of the car radio.if black wire joined together ...to give ground should they touch any metal body...like mounting the cd in the car .....
