Help! How do I get power to my new video card?

[VvWolverinevV]

Hey, I just got a Sapphire Radeon x1600 Pro video card, but I got it through newegg.com as an open box item (so it did not come with any power cables). I've been using the 4-pin power cable that was plugged into my firewire card, but now I would like to use my firewire ports again.

Here is what I have available:
1) a spare 4-pin cable with 4 wires (red/black/black/white)
2) a spare 4-pin cable with 3 wires (red/void/black/white)
3) a four-pin motherboard connection labeled P7 CD
4) a four-pin motherboard connection labeled P11 AUX
5) a four-pin power cable from the power source with 4 wires (red/black/black/orange)

Is there any way to power both my firewire card, and my video card with just these materials? If not, what else do I need?

Nevermind, I found the answer myself:

Apparently, P7 and P11 are inputs. It looks like I need an AGP power extension cable:
