Would this power supply be enough for SLI?

In this system would this power supply be enough for sli? I intend to overclock to 4.5 as well... I am curious becuase someone said he could not SLI with 2 660's HE did however have liquid cooling which may use a ton of power.

More about would power supply
  1. I'm not an expert, but by the looks of it i would say it's plenty for x2 660's.

    Try one of those wattage calculators, and see what it spits out, just so you have a number to go for. Not sure if they're 100% precise though.
  2. I tried in one of the calculators for two 670s... probability was the guy was an idiot or got a faulty supply unit. I got the TX enthusiast 750 though becuase the CX I mentioned did not have as good of rails.
  3. I'm pretty sure it is enough, as i've seen one with a 650w psu in a worse tier than yours, running sli 660.
