New Asus Radeon R9 280X and an Emerson 32" monitor not displaying anything??

I purchased the new Asus Radeon R9 280X Graphics card. I was using the Nvidia 560Ti with an Emerson 32" monitor. I connected this card to the large monitor using the HD connection on the video card and monitor. With the 560Ti I never had one issue, from installation on. I removed the 560 Ti and installed the R9 280X using the same hookup as I had with the 560Ti (HD cord).

I can see that the new graphics card has power by the red and green lights on the bottom of the video card. When I connected the card I used the accompanying power supply adapter. What I did notice was even though I have plugged into two separate cords coming from the power supply, (using the adapter), there was only one six pin I could plug into on the new 280X. This leaves one six pin area on the graphics card not in use. This leads me to ask, " does the graphics card have enough power to perform?
Now, if it does because I used the adapter, that was supplied with the new 280X, "why am I not getting anything as far as a picture on my monitor.

Any guidance and or advise you can give is greatly appreciated in advance.

Best Regards,

Stumped in Indy.

  1. I would recommend going back to your 560 Ti and go to Event Viewer. Once you see what happened, you can fix it.
  2. "This leaves one six pin area on the graphics card not in use" this is your problem. The Asus 280x requires both power connectors to function. IF your PSU lacks these connections it usually a good sign it needs replaced. Whats the make and model of the PSU you are using?
