View Full Version : Crossfire PSU Help!
27-12-2011, 02:16 AM
So I recently bought a new Graphics card and PSU. On newegg they brag about how it's Crossfire ready but it has 4 6pin slots and only 2 8pin slots. On the PCI express cables for both of my 6870's there's 6 pins for the side you plug into the GPU and 8 pins for the side that you plug into the PSU.
So what the fuck do I do? I've read about Molex cables but I don't know how to set them up and I only have 1 of the 2 I need. So is there something I'm missing here? Anyone ran into the same problem?

I don't really understand what you're asking - each card will have two 6-pin connectors on it. If the PSU has four of these then you're good to go. Are you trying to use cables that didn't come with the PSU?
It would help if you at least linked the model of your PSU, that way we can see exactly what connectors it has.

here's the models
I'm saying there are not enough 8 pin slots in my PSU to plug in both crossfired GPU's. The chords that came with the PSU have 6 pins on one side and 8 on the other. Same with my first GPU.
You have a 6-pin and 8-pin PCI-E on the PSU and each 6870 requires 2x 6-pin. You'll need to get two 4-pin molex to 6-pin PCI-E adapters (something like http://www.newegg.com/Product/Product.aspx?Item=N82E16812196870 but you can find them cheaper elsewhere; newegg has several, also check monoprice and meritline).
