HD 7970 6ghz Crossifre

post #1 of 5
Thread Starter 
I currently have the one HD 7970 Vapor-X. I'm looking to crossifre it. I have a question about the pci pins.

As you'll see the card has 2x 8pin connectors and I use an 8 pin and a 6x2 pin from my PSU. What will happen when I add the second card? Will I need to upgrade my PSU so that it has an additional two 8 pin connector?

not sure about 7970's... my Antec 650W ran crossfired 7870 Hawks with first one on the PCIe power connectors and the second with the 4-pin to 6-pin adapters. can you purchase a dual 8 pin cord for that PSU?

OP don't jump on HD 7970 CF. i suggest you wait and see how Hawaii performs. if the rumours are true a single HD 9970 or whatever its called might be a better option. wait till oct. these cards are expected to come bundled with BF4 thumb.gif

Sounds like a plan since it'll come with BF4, however the price for a HD 9970 will probably be extortionate.
