I'm sorry if this has been asked already but I couldn't find an answer. I currently have a Corsair AX760 and I am looking to buy this set of custom BitFenix Cables on Amazon. But are these "Extension Cables" or can I just connect these directly to my PSU. It looks like I can just hook them up but i just accidentally bought "Extension Cables" so now I'm worried and would like to but the right ones. Thanks for any help guys
