Graphics card issue or is it?

[MCount]

I have a Gigabyte Radeon HD 7970 3GB Video Card that I had initially purchased for my computer build and later on I decided to purchase another graphics card to crossfire and I did. I had purchased this time a Gigabyte Radeon HD 7970 GHz Edition 3GB Video Card but since they're the same series I figured that they would be compatible. After installing it I came to the issue that it was not being utilized at all, I checked to see if it was a dud and it wasn't. Crossfire x was enabled on my catalyst controller with all full updates of my drivers. Only thing that comes to mind is possibly my PSU can't handle it all, I have a NZXT 850W ATX12V / EPS12V and have not OC'd my CPU. What can be the problem, unless their isn't and I'm just thinking their is.

Edit: Here is what I'm looking at through my catalyst controller of my first card showing activity. And here is my second card showing signs of no activity.

I have an ASRock motherboard z77extreme4 and 2 PCI-E slots and the board does support crossfire, and yes my PCI-E cables are all conected from my PSU.

So what indicators do you have that tells you it is not working?
So far all you say is, "After installing it I came to the issue that it was not being utilized at all."
We need more info to get a grasp of your situation.

Here's more of what I'm seeing, is this normal for the other graphics card to be fully idled? Here's the primary graphics card that shows activity. (First Card) And here shows the second graphics card showing signs of no activity. (Second Card)

Run gpu-z look at the firmware on both cards. The ram speed of both cards and the gpu speed. If the ram and gpu speed are not the same..crossfire or sli won't work. Sometime it screws up with two cards that the firmware not the same.

I would hazard a guess that the one card idles down if it is not needed.
Can you capture these screens with a heavy load on the graphics cards? I don't know say 3D Marks or something that will use both cards?
