Calling all Corsair HX-850 owners!!

Ok guys, i just got in my new HX-850 PSU, and i have one question about what PCI-E cables i should be using to connect up to my 4870X2. Now the PSU has two 8pin PCI-E connectors that are already coming out from the PSU. Now im guessing i can use these two connectors straight away and hook it up to my 4870X2? or should i be doing something different? like using the Blue connectors and cables and hooking it up that way?

I do plan on going Crossfire in the future so should i then use for one card the PCI-E connectors that already are attached to the PSU and then connect another two Blue connectors to the other card? or am i getting my self realy confused here

Anyway just wanted to make sure before i put it all together and did it wrong and BANG!! there goes my card etc.

Corsair HX-850 is a Single Rail Design.
Use hard wired PCI-E for motherboard connections first, if any. (near CPU)
If not used for motherboard then use for 1st Video Card.
Then use modular cabels for other Video Card(s).
On mine the Black End goes to the Video Card.

Now thats what i dont get, im lost why they would give you hard wired PCI-E cables for the motherboard?

Going by the user manual it says, If your video card requires two PCI-E power connectors, do not connect a hard wired/captive PCI-E connector and a modular connector to the same video card. It is recommended to use either hard-wired/captive cables or modular cables, but not both on the same video card.

So going by that^ i think i can use the hard wired ones to the Video card, but i should NOT use a mix, like one hard wired and one modular connected to the Video card.

EDIT: Ahh i didn't see you editing your post, and yea that is how i thought it would work.
