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?

If I'm correct, that cable on the right of that pic is an 8 pin PCI-e cable. It looks like a 6 pin cable, but there are two extra pins on the side that look separate, but they go with the 6 pins to make 8 pins the same way your CPU power connector is probably two 4 pin connectors.

Those both look like 6+2 power connectors to me and should work fine. Get rid of those adapters and try those out.

I tried without its adaptor thing as you said. Nothing changed. The lamps and fans are working but windows still doesn't start. Should I RMA it? If I do, what shoul I say to the retailer?
 


That is plenty. so that honestly only leaves the GPU and the motherboard.
Check for a BIOS update and try that otherwise it might be a bad GPU if you just got it I would call ASUS
though motherboard could not be compatible seems less likely though.
