They're for gpu's that require extra power

 

[sizzling]

Or other pcie cards that need additional power.

They could, yes, but I can't think of anything that would except a GPU.
I've seen pcie cards take the old 4-pin molex as well as the newer Peripheral (sata) power cables, but nothing else (yet).
