How to do crossfire with Corsair TX 650W ATX SLi?

[WazMeister]

I am trying to do crossfire.

I have 2x 4890s

1 taht came with my Titan Sabre pC from OC.co.uk and another 4890.

The one that came with the PC has 1 6 pin and 1 8 pin, which I've read needs both.

So how do I plug in a 6 pin in the other 4890 with this PSU? It only has as far as I can see 2 6 pin PCIE slots with 2 pins added to one which makes 1 8 pin and 1 6 pin.

Am I doing something wrong, a post a few weeks ago, people told me I could do it easy...

Any help

Thanks

I presumed I cant just use 1 6 pin in each, I'm guessing my current 4890 does have to have the 6x and theother 6x with the 2 extra pins to make 8.


How do I go around getting my 2nd 4890 in with power?
Some form of adaptor?

650W isn't a lot of power, so maybe ur not meant to. But maybe you could convert one of the other cables somehow.

This, since it will probably not need to use that power connector much. It's only recommended to have 600W for Crossfire anyway.

So I plug that on and then the 6 pin can go in the other 4890?

The PSU should be ok, my last post people said it is defo fine!........

The other 4890 has 2 6 pin plugs, do I only need to plug in 1 though?
