Fast info on 7970 crossfire and if my PSU is enough

post #1 of 3
Thread Starter 
I have looked around and did some research and it seems it will be OK but I wanted to ask for sure. I have a Corsair AX 850 have my I7 at 4.5GHz my 7970 GHz is at stock as the windforce cards don't really overclock as they have locked voltage. Now I have 4 corsair fans on my rad with 2 200MM fans and one 140mm fan. I also have one 150GB 1000 RPM rapter hard drive. I have a 128GB Samsung pro 840 and a older 128GB Samsung 870. I also have a swifttech 655 pump and a blue ray and CD burner. Ah and one more thing I have the sound blaster Zx sound card. I am pretty sure that is all that really drawing power if I pop another 7970 Ghz edition with out overclocking them will I still be around 750 watts or so I don't want to push this 850 to the max as I want to keep some of its efficiency.

Also I have my 16GB corsair 2133 ram at 1.5 volts almost forgot. Anways will all this stay in the 700-750 watt range at full load or am I pushing it too close. Thanks alot again guys as I'm sure you will have fast replays.

Yes, I too agree that your AX850 will be fine.
