So yesterday I spent £160 to buy a new graphics card and today when I received it, I realized there was a big problem. My PC does not have a 6 pin cable to power my graphics card. Please help me, what do I do? I have unplugged everything off my motherboard and searched for a 6 pin cable but I can not find anything. Please help!!
