8 pin split PCI-express cable to power my single hd 7870?

Would it be ok to use an 8pin (from the PSU) split PCI-E cable to connect to both slots of my hd 7870 or would this cause any problems for me?

I have a 500w CX500M corsair PSU
CPU: amd fx6300 blac editon 3.5ghz

The cable I'm planning to use it like this one, but has an 8pin on the PSU side rather than a 6 pin.

if you need any more info I'd be happy to help.

  1. That is normal.
    A psu maker will often use a 6+2 connector so the user can connect either 6 or 8 pins.
    For a 6 pin connection, just leave the +2 dangling.

    sorry, I don't think I wrote my question how i should have, but thank you for your answer.

    The cable I am using is a fixed 8 for the PSU port and I can't seem to break it away to make it a 6. it also has 2 leads that fit into my GPU while still being a single cable. Would it be ok to use the 8 Pin slot on my PSU and then connect the 2 6pins into my PCI-E slots on my 7870 or would something go wrong? or would you recommend using two 6-pin slots for the GPU ports. I'm assuming both GPU ports have to be used or the card won't work. also, I'm not sure I have enough space on my GPU to fit another 6 pin in.
  3. THe simplest way I can describe the cable I have is as follows: The cable starts with a fixed 8 pin, it then goes along until it breaks off to a 6+2 PCI-E, then continues to another 6+2 PCI-E.

    That is what you want to use. The 8 pin end goes into the modular psu, and the two 6+2 ends go into the graphics card.
