Short answer, no. Especially not with a FX 8320 @ 4.6ghz . I'll let others chime in for recommendations of psu's if you want to still go forward with crossfire, but I'm in the same boat as you. Been considering 290x crossfire (own a single now) but I know I'll be stressing my NZXT Hale-82 850w just too much to trust it long term, especially with the fx-9590 as well

His 850w CM Silent Pro is more than capable of powering two 290s and his FX-8320. Only if he plans on OCing his cards a lot will he run into actual trouble providing power.

 

His setup is perfectly capable with his GPUs fairly close to stock + his CPU.

Never understood this train of thought. Do you not see a problem at all with the bolded statement? The fact that you have to say, well it's fine, but 50 more watts due to overclocking and now it's an issue!

Sorry, I'm not one to risk $800 in just gpu's alone due to being at and/or near the max of my psu simply because it technically can run it.

but 290's aren't using same power as 290x. it's around 50w less each.
