Molex power connector question

I will be installing a PCI Express x1 card.  I have to connect a 4-pin molex power connector to the card.  I see 4-pin power connectors labeled P4, P6, etc.  Can I use any of them?

The card power header will dictate the type of plug you will use. I am linking connectors here because your confused. Although the molex, floppy, and ATX all have 4 pins, all are different designs. The ATX also has a different electrical output.

The one I'll need is the top middle in your link.

 

I see a few molex connectors in my PC case.  

The wires coming out from behind the 4-pin molex connector is attached to a SATA power connector. 

So can I attach the 4-pin molex to a PCI Express card?

 

Here is a photo of my connector.  I've circled the white 4-pin and SATA power connector that has wires connected to each other: https://drive.google.com/file/d/0B8srMBzeAceoaVoxdllnSnNfeUk/edit?usp=sharing

 

This is an example of the PCI Express card I might purchase: http://www.newegg.com/Product/Product.aspx?Item=N82E16815166026&cm_re=rosewill_pci_express_usb_3.0-_...

 

You can see the molex in one of the pictures in the newegg link.

Re: Molex power connector question

Yeah you can use any molex power cable for your add-on card. They all output the same voltage (5v red wire, ground black, ground black, 12v yellow) so your good to go.

The card you referenced will access the 4 pin molex.
