Sapphire HD7950 Vapor-x details? PSU suggestions?

Last response: in Graphics & Displays

Hi all, Ordering today

I have been comparing these 3 models at newegg:

http://www.newegg.com/Product/Productcompare.aspx?Submi...|14-202-006^14-202-006-TS%2C14-202-003^14-202-003-TS%2C14-202-007^14-202-007-TS

In the comparison I notice the vapor-x has the boost feature, but can't the same thing be achieved by overclocking the cheaper model? I also noticed that the vapor-x model need two 8 pin connectors; would I need a special type of power supply/connector for that?

Does the vapor-x only have a better cooler, or does it have an overall higher standard for parts? Is there a better card I can get for around the same price ($325)? If the vapor-x model is a good choice, can you suggest a suitable PSU for it? (System I plan to build with it: 3570k OC, GA-Z77X-UD3H, 8GB RAM, 1tb HDD, 128GB SSD, DVD burner, not xfiring)

Thanks.

Thanks for the response, the Rosewell PSU specs look good (it's even modular) and I have heard that their build quality has improved in recent times. I have also heard good things about Corsair and Seasonic PSU's and I won't mind paying a little extra if these companies have better build quality i.e. Japanese caps or longer warranty. Are there any suggestion for Seasonic or Corsair PSU?

Will this PSU have the 2x8pin connectors that work with the sapphire Vapor-x HD7950? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Best solution

Graphics card Master

From the reviews of the Sapphire HD 7950 Vapor-X and Sapphire HD 7950 Flex, that I've read, the Vapor-X was able to overclock 110 MHz higher than the Flex all while doing it with less GPU voltage.

Thanks for all the help.

"What concerns do you have about the 2 x 8 pin connectors? "
My last video card used one 6 pin connector, I wasn't sure how I would connect this video card. Guessing I would go 2x4pin for each 8 pin? Would I need an adapter?

The power supplies that have been recommended already have two (6+2)-pin PCI Express supplementary power connectors so you don't need to use any of those adapter cables that come in the graphics card package.

Hi kanoobie, I know this is an old thread but I just wondered how you got on with the Sapphire 7950 VaporX???
I'm just about to order one for my new build and one of the things I was also a bit confused by was the 2x8pins requirement. I was more confused over the fact that Sapphire themselves say it requires 2x8pins but a lot of sites posting reviews about it were saying it was a mistake on Sapphires site and it only required 1x6pin and 1x8pin! :??: 
So may I ask what was yours, (1x6 & 1x8) or (2x8) and how are you finding it, any problems or advice???

Thanks :)
