How to make IEC to Molex connector?

[Arnxt]

Hello! This is my first post and I am not very good with english, so please correct me if I am wrong anywhere.
I have a IEC to Molex connector which I used to connect internal CD rw or HDD to power supply from wall socket.

But it is not working now. I tested it and found out the Molex female end is not working but other parts are ok. I cut the covering wire between IEC c14 (male) adapter to Molex (female) to find three wire inside i.e. Red, White & Black. Here comes my first question what are those wire? I think red is positive, black is ground and white is for? Correct me.
I have a Molex (female) lying around, salvaged from my old PSU and I was thinking to connect this in place of that damaged Molex (female). So my next question is how to connect the red, black and white wire from IEC c14 (male) end with the red, 2 black and yellow wire from Molex (female) end? Also I must mention that the IEC c14 (male) end is an adapter converting input 100-240volt, 10 Amp to output 12volt, 2 Amp and 5volt, 2 Amp.

The IEC C14 connector is the PSU-side socket for the wall plug. A C14 to Molex adapter is essentially a PSU. The C14 has a live, neutral, and ground. This is an AC powerline connector. The Molex/AMP 4-pin disk connector has a +12, GND, GND, and +5. The Molex/AMP connector is a DC, regulated connector. They are not compatible, and require a PSU to connect one to the other.

Also, 100-240 volt, 10 amp is between 1000 and 2400 VA or watts. That's the rating of the wall-to-PSU cable in most cases.

That said, you can find the pinouts for any of those pretty easily.

@the nerd 389 I did not understand why it is not possible! As you mentioned, the adapter is essentially working as PSU. So the cable going out from the adapter to the Molex female must be already carrying converted AC current to DC or all the other related/necessary conversion is already happening inside the adapter as it was WORKING for last 1.5 year. What I am wondering that there must be a way to replace the Molex female terminal with the same as the connection is already there under those plastic covering. Any electrical engineer out here?

this looks like a power supply of some kind can you picture the label of it, it could be simpler to replace the unit completely.

I think you're asking if you can replace the 4-pin Molex connector that is currently on the AC-DC converter in the pic. The answer is yes, but it probably wouldn't fix anything. The connector itself is very well built, and I've never seen one break. The sockets that they plug into are more fragile.

PSUs and AC-DC converters, on the other hand, break pretty frequently. That's probably what happened, and while it is technically possible to repair them, you can start a fire if you mess up.

You should just get a replacement.
