6 Pin GPU power connector question???

Hey everyone

I figured I would drop this question here in the PSU section.

I have noticed that Video Cards ship with a 4 pin MOLEX connector that terminates into a 6 pin Video card connector.

Here is my dilema and I don't know why the item is configured the way it is. There are 2 black wires, 2 yellow wires, and 2 Brown wires split across the yellow??? 1 of the pins on the 6 pin connector (center pin) is open/empty and it is on the yellow "power side". Here is a reference picture.

OKAY

Now I bought a new power supply that says in the manual "plug the 6 pin PCIe power connector into the video card". This 12V line comes right out of the back of the PSU.

No problem, but i noticed that this connector has 3 yellow wires across the top (assuming all power) and three black across the bottom. But the connector that came with the video card doesn't look like this and has the open middle position and brown wires.

Why do manufacturers do this? Why does the power supply 6 pin connector differ from the 6 pin connector provided to me by the video card manufacturer?

Will I burn out my video card if I plug the one from my PSU into the back of my video card.

I have the MSI 8600GTS. Everything is new in my case and I just don't want to fry anything!!!

It's a PCI-e connector. Standard wiring. Who cares if there's a stripe on the yellow? Hell.. I could make the wires blue if I wanted to. And a missing +12V wire or ground wire just means more resistance not that fires are going to start.
 
I have always thought that a 12V line applied to a curcuit board where it IS NOT supposed to be applied is a bad thing???

Since when does adding or removing power from where it is needed to a place where it is NOT needed ever good for electronics???

That is why I asked the question. The power connectors (one from the card manufacturer and one from the PSU) are wired totally different with different colors.

Colors and PIN location means something in electronics.

Anyone else care to add anything...so basically I just plug in the PCI-e connector into my Video Card and all should be fine???

Oh... the brown is a ground. The missing pin on the Molex was a +5V. Something PCI-e doesn't need. I still don't see the concern. You think there's two different pin-outs for PCI-e 6-pin connectors? No. That's not correct.

Colors: Black is ground, brown is ground and stripes designate that the lead is from the same voltage but a different source. Not something to freak out over.
