Sorry, I'm a noob, I'm using a 280x for the first time. I have ASUS R9280X-DC2T-3GD5. There are 8 pin and 6 pin slots but I don't have any 8 pin connector, so I used this branch thing with comes with the box (look at the pic, in the middle) and six pin connector comes from my PSU. When I start the comp, the green lamps are lit and fans work but the windows doesn't start. Where do I wrong?
