I bought this graphic card few month ago, and I tried to plug in 6+2 pin without success. Then I plugged in one 8 pin, that has two 6 pin on the end. And it worked, but there were red light. Then I read somewhere that there is a green light too, so I got confused. I searched a bit, and I found that it is needed green light. So I tried again, and successfully plugged in 6+2. What do you think? Was red light bad? Graphic card always worked without problems...
