What are these and is it possible to get adapters for them?

[treebearhunter]

So I got given a new HP desktop pc that has an i7 3770 in it and went to put my graphics card in (HD7870ghz) only to find the power supply has no pci 6 pins connector OR molex connectors so I couldn't even use adapters, so this should be a simple fix right? just stick my old cx600 in there, right? WRONG, the motherboard seems to use some weird power connectors with one having space for 6 pins in a straight line, although it seems to only be using 4, labeled with "P2" and the other which I assume is the main power has 6 pins similar to the pci power cables and is labeled with "P1". Heres some pictures of the "P2" connector (http://i.imgur.com/rGZ2hCC.jpg, http://i.imgur.com/y2BVVSt.jpg) , now my question is pretty much the title, What are these? and can you get adaptors for them so I can put my old psu in the pc?

That is an older power connector for HP int video, since you have upgraded your graphics card you will have no need for that anymore.
