amd gaming computer need psu help.

Yes I have a 8320 which i want to overclock and i want to get 2 r9 290's to run crossfire the question i have is this, what psu would i need to run this, i'm gonna have 3, 120mm corsair fans, 4 140mm corsair fans as well with it and i just need a second opinion. I was told to check out cool master calculator advance and i get 785 watts. I do plan to overclock my cpu to 4 gigs which isn't too extreme but i just want 4 gigs out of my 8 core. I want to also overclock the 2 r9's to 1000-1050mhz but i get stuck with the whole 80 plus. Now i do know that a 800 watt continuous power would be perfect at 100% load on the whole computer, i just want to know if 800watts would be enough with the non-extreme overclocking.

You will be fine with a 850w PSU. I have almost the exact setup, just higher clocks.

Always buy more than you need, psu's sun better when not under full to medium load all of the time.  I'm not sure how accurate the calculator is, and I'm not an expert on psus'.

You should be fine with a 850W PSU with some pretty decent OCs
