8 pin Female to 6 pin Male pcie power adaptor? or alternative?

[Slav2012]

So i want to run sli on my power supply but dont have the right connections. The power supply is the Thermaltake toughpower 750w modular cable management power supply. It has 3 x 6pin pice connectors and 1 x 8 pin power connector. The 8 pin in not a 6+2 but just straight 8pin. I was wondering if there is a adaptor for a female 8pin to male 6pin connecter there for making it easy for me.

I cant seem to find it in my local comp stores or on ebay? but im assuming it must exist? right?

You can get an 8 pin to 6+2 pin extension.
