Could my PSU cope with Crossfire?

With the release of the AMD 390's getting closer I'm thinking it wont be long for the 290's to drop in price, this has got me thinking about getting another 290 for my system (Specs in sig)

Do you guys think my EVGA Supernova 750W Could cope with another card?

Cheers

You would be looking ok, if you look at the review for your card below which the whole system pulls 384w whilst gaming adding a second will not get upto 750w.

I don't think we will see anymore price drops on the R9 290, it is a card that is very well priced already and will only drop when they start being sold second hand with people upgrading to the R9 390, which is still a few months off.

Do you overclock your card?

If not, why not?

If you do, you'll need more than a 750W to power both if they are overclocked.

I have crossfired 290s, partnered with a heavily overclocked FX CPU. I also have 3 pumps and 10 fans.

Power consumption never exceeds 700W at the wall, with both GPUs fully loaded. More common power consumption is around 600W.
