Crossfire with only 2- 6pin PCI-e outlets on PSU

[Dirty Durden]

I have a single ATI 4870 now & at some point I what to add another 4870 to the system. My PSU is (CoolerMaster Silent Pro M700 RS-700-AMBA-D3) with 2- 6pin PCI-e outlets on the PSU. My question is will this PSU let run 2 ATI 4870 in crossfire or do I need a PSU with 4-6pin outlets (the PSU says it is SLI ready, but does not says anything about Crossfire)?

If I can run 2 4870 will I only run 1- 6pin to each video card?

No, both cards must have all plugs inserted, otherwise they won't run. If you are confident you have sufficient power, you can get converters/splitters to get your 4 PCI-E power plugs.

Yes I think there is enough power with +12v @ 50A with total output @ 700w. What does this converters/splitters look like & do you recommend a brand?

Thanks

This looks like a decent one. This is the way my PSU does it from the manufacturer (1 6 pin to 2 6+2 pin) so I think it should work. This is not the only option though, browse around Newegg to see what else they have (and other sites as well).

Or you can get a couple of molex to pci adapters. My 4870 came with them.

Yes I have those but I want to add another 4870 into the mix so I need another 2-6pin from the PSU
