Hi, I have upgraded my gpu from an Asus gtx 670 to a Gigabyte gtx 1080 and I've noticed there is now a lot of noise/interference through the speakers of my home theatre setup that wasn't present before.


It seems to occur when the gpu is under load, like when I run furmark or use the oculus rift. Everything is the same apart from the gpu which was upgraded, the proximity of the computer and the routing of the cables are all the same so I don't know why this only happens with the 1080. The 670 needed two 6 pin power connectors but the 1080 only uses one 8 pin power connector, could this be why this noise didn't occur on the 670?


My pc is connected to my hdtv via a hdmi cable and my home theatre stereo/amp is connected to my hdtv via a line out on the back of the tv. I have noticed that the interference gets louder when I increase the volume on my home theatre stereo/amp but not when I increase the volume on my hdtv so I assume the interference isn't coming out if the hdmi port and doesn't have anything to do with the hdtv.


Is this normal? That one gpu is fine but another creates noise/interference under the same circumstances? Or is my new gtx 1080 faulty in some way? I do get 120 fps in the furmark 1080p benchmark which seems fine when comparing the score with others so the card seems great apart from this noise issue.


Any help or advise you can offer is greatly appreciated. Thanks!
