How to connect a HD 4870 ?

I just received my Power Color HD 4870 PCS + 1GB and I got a question, how it should be connected.

I have a 430watt power supply antec true power which is a bit old and so I do not have pci-e connector 6 or 8 pin, I do not know molex adapter (I was aware but I think not that very smart on their part). But fortunately my 8800 gts used in one (which was included in the bundle)

There are 2 places to plug in a pci-e. Is what I need to connect 2 molex adapter? Or is that just for the pci-e 6 pin which as I understand, less powerful than 8 pins and must therefore 2 provide enough current.

There is a strong chance that the two are mandatory.

If an old antec true power 12V then I will just not be enough
at worst it could heat and seek safety.

and must connect the two (RTFM?)

Yes we must connect the two. But it's good to know that Power color does not come with adapters with my Sapphire, there were 2 to provide.

I also ask myself the question I intended to buy a Gainward 4870 but I need 2 connectors and my power supply does a pci express. Will I then not to use it and connect 2 adapters on free molex taken? Adapters are provided?

We must connect the 2 PCI-E 6 pins.

For those who are missing PCI-E 6 pins, via adapters ...
