This card requires an 8 pin and 6 pin connector? my Corsair 650w TX650 PSU only has 2 PCI-E 6 pin connectors right? so how do I use this card with my system?

If I am not wrong you should be able to get a 6-8 power cable....

ALL TX 650s have two "6+2"-pin connectors (meaning that you can easily detach unneeded 2 pins, or attach them when you need them, thus making them "8-pin" cables in actuality), MSi's "HD 7970 Lightning" needs two 8-pin cables, while XFX's "HD 7970 Double Dissipation" need one 6-pin and one 8-pin. Just attach additional 2 pins to one of the two cables (if your HD 7970 is XFX's, for example) and everything will be just fine.

That makes sense, and I do have the cables you are referring to, however, I tried it and the computer booted up but my monitor wasn't showing anything. Any ideas?

my monitor runs with 1 6-pin connector attached, I put the other 6 pin with the attached 2 pins and my monitor doesn't show anything. To clarify that is 2x 6 pins and 1x 2pin cables attached to the video card. I try installing the driver for the video card and it wont allow it because the device is not detected.

Then it's most likely that it's something in your monitor, or connection to it.
Which type of connection you used? On which card?
These days it's better to use DisplayPort connection only ("Dual-Link DVI" being the second best), as it works best.
You probably connected via HDMI? Or you monitor needs double DVIs to work... :\
It's not that of a rare thing these days. Personally, I hate when monitors demand double DVIs to work, I always connect only through DisplayPort (if available), it works the best.

Uhhhh....what? O_o
It's one cable, man. 6+2 is ONE cable, it just has 2 pins hanging near the main 6 pins, you just need to attach 2 pins if you need 8-pin connection, you don't put in 6 pins and then some 8-pin cable from the side....now I'm confused...

......what processor and socket platform do you have? What is you motherboard (like H67 or Z68/Z77)? I think I'm starting to get the picture...

Sorry this is my first build. I've also noticed while messing around that my power supply fan isn't on. I'm not sure if it goes on when necessary or if I don't have something hooked up. I tried running the video card with both connected while only having the blue connector attached, but it had the same result.

Oh, the video card has an 8 pin spot to connect and directly beside it has a 6 pin slot to connect, i have a 6 pin connected to the 6pin connector and a 6pin+2pin connected to the 8 pin spot when my monitor doesn't work. It does worth with just the 6 pin connected, but the driver disc doesn't recognize the video card.

Just as I thought...
Just unplug monitor from your motherboard's video connector and connect it ONLY to video card. :\
They don't work together at the same time. You can either connect it to motherboard, or to video card, you can't use one monitor on both.

It's Corsair, man. It should be like this, don't worry.

Yes, exactly that.
