750W enough for two CFed 7970 @ stock and an OCed 3570k?

post #1 of 6
Thread Starter 
Running into a problem as i bought an EVGA 750W PSU before i had intended to CF. I know that OCing the 7970s in CF is out of the question and am wondering if a 3570k overclocked and two stock 7970s is still to much strain?

Or should i put it on Ebay or F/S and try to make 80-90% back. I've had it over a month so I can't send it back.

Think i could push the GPUs and Cpu? We're talking say 1100/1500 on the GPUs and 4.0+ on the CPU. I think on Water i could push the GPUs farther but sites have the 7970s in crossfire stock drawing around 500W so a decent overclock to 1000-1100 might be max. Though i'd love to have the system specs look like this lol

i5-3570k @ 4.5ghz
2x7970s @ 1200/1600

Would be a monster.

1200/1600 is mild oc. Probably you should worried about 1.3 volt or more on each card. Either way i believe 90% you are fine. You must get 2 golden cards to get 1300 on both

Hell i figured i'd have problems getting to 1200. That being said i haven't had a good 7970 with my XFX. Though this time i'll be going reference with Diamond and it seems they clock very well according to most that own them.
