Hello everyone, yet again I am planning on upgrading my gpu (this time to a EVGA 960 4GB SSC).
However, when I was looking at the Type 3 cable for my Corsair CX500M power supply, it doesn't seem correct?
The cable has 2 wires going into 1 hole therefore leaving 1 of the holes empty.

Here's some images of the cable:

Is the cable meant to be like that or did I unlucky with a faulty cable?

Also, since the type 3 cable has 2 PCIE endings, does this mean that I can plug them into a gpu that uses more than just a 8pin connector? or does it have that feature for multiple gpus?

Thanks to anyone who can help :)

You have a correct PCIe cable there. The pin that appears to be missing would supply 12V but PCIe only uses 3 12V, the other 5 pins are ground. You can see the double wire coming from the pin below the empty connector, that's the 4th and 5th ground ground wires which is why I say it's correct.

Looks like you got unlucky and got a faulty cable. And the two endings are for cards which need 8PIN+6PIN to work. Dont use them for multiple cards. You'll need another cable coming from the PSU for a second card. I dont think two cards would get enough power over just one of these.

An 8 pin cable can supply 150 watts ... 6 pin 75 watts and the PCI slot 75 watts.

8 + 8 + Slot = 375 watts
8 + 6 + Slot = 300 watts
8 + Slot = 225 watts
6 + Slot = 150 watts

The SC series is a reference quality card so won't draw that much. The card maxes out at 166 watts under Furmark.

166 - 75 = 91 watts gotta come from the cable(s)

Oh ok, so would I be able to use the cable then? I'll have to use the extra 2-pin adapter thing because the gpu will use a 8pin connector. Also, the two cables that were confusing me only connect to that extra 2pin adapter so is that how it's meant to be?

Yes, you can use that cable and yes, that's how it was designed.

Although I won't suggest doing this (since it's time consuming and serves little purpose), if you look at a few different brands of modular PSU cables (notably PCIe cables) you find an interesting variation of designs - all seem to be valid (although I have personal views about some of them).
