Can I crossfire with this PSU?

So, was thinking of getting another 5750. Just looked, Ive got space, mobo supports it but my PSU is this one:-

It only has 2 x PCI E power connectors - both are used for the current card. Is there a way to crossfire without another set of connectors? I assume both cards need power to them in crossfire mode or does the bridge carry some power?

I could possibly get a 'splitter' for the cables - not sure if there is enough power in the PSU for this?

Thanks

Most times the GFX card will come with a molex to PCI-E power adapter.

That PSU is good enough.

Ah, didnt think of the Molex option, thanks. Only a few hours left on this auction, so will go ahead and bid on it, thanks.

Thanks - might have some around. I won the card, put a max bid in and it came in £1.77 under my max ;p. Will collect tonight likely and if all goes to plan, will be crossfiring. Time to get something a bit more demanding on my machine to test with.

What 3D mark or similar are ppl using these days to compare?

The Furmark benchmark is a good test (Takes less time to run than any 3DMark)

For GFX performance results it might be best to ask in the GFX section or look through the 3Dmark and Heaven benchmark threads.

Did a Furmark run and it scored 3300ish on the 1920 test. Seems that Crossfire is working, BF3 feels good. Thanks.
