Thread Starter 
Thanks svenge. Not into OCZ psu's. I did read that link for the oem Super Flower. Gonna wait and see if I have enough juice, if not EVGA it is! Can't wait for my gpu. 2- Asus 7970 Matrix's watercooled is going to look soooo sweet!

Doesn't look like it's going to work sticking with my 750. Each gpu does fine by itself, but as soon as I crossfire in games it sure enough crashes. The newer malta design for 7990 is 36% more efficient than 2 - 7970's and it needs 850w.

Forget the EVGA SuperNova G2 when there is a P2 on the way

Or any of the other new PSU´s on the way

Were you overclocking your CPU before the addition of the second card? Attempt to increase the voltages of the CPU a notch. By adding another GPU, there's a larger voltage drop that the VRM need to handle, which may drive the operating voltages higher. This may cause your overclock no longer to be stable with your current settings.

ah, when you say "crash" do you mean shutdown. because with over 700 watts that X series can supply on the 12 volt rail; i am highly surprised it won't support a ~150 watt overclocked system with up to 500 watts for the GPUs.

That sounds like a good possibility. I'll give it a try.

No, it doesn't shut down, it hard freezes while gaming. I'm not sure of voltage, but I got a 2 massive watercooling loops and both cards run at 1100/1600. I also have had a single up to 1375/1880. So, we're talking highly oc'd system.
