your aware that the psu only has 2 6 pins and you need 4 for a 6950/70 CF. the wattage isnt enough either.

same story for the 6870. the close you can attempt would be a 6850/7770/7850 but I still wouldnt recommend that entirely

It would likely run the 6870s...but I really wouldn't trust it. I'd get a 750w at least for the 6950s, and probably a 650w or higher for the 6870s.

Well, it seems I don't know anything about PSU, if I were to put both the cards in would it just not turn on?
Could you guys find a couple different PSU on Newegg that would work that I could pick from?
I did that calculator thing and I think I did it right and it says that my recommended wattage is only 551

Yeah I just double checked with that calculator thing and with running both my HDD and my Disc drive (which i don't need my disc drive or one of my HDD, it says that the minimum psu wattage is 513 and recommended is 562. Am I missing something here?

not sure about that psu, but i can vouch for corsair TX 750, TX 850 and AX 750! i saw them handle heavy stuff

Best solution

Wattage isn't the only thing to look at. You need the 12v Amp output for two video cards as well, plus enough 12v PCIe cables to plug in to the GPUs.

So I do'nt have the 12v amp outputs on my current psu? it says it's sli ready, i figure if it's sli ready it's probably crossfire ready.

SLI ready doesn't really mean all that much these days. All it means is that it has 2 PCIe power cables and the ability to run 2 mid/low range video cards. It would for example run a pair of 550's in SLI, but put in a pair of 560's and you'd be stuck only able to plug one card in.

SLI ready is a marketing gimmick
