I heard that R9 295x2 can pull about 500 to 600 watts by its self that leaves about 350 to 250 watts

a gold certified 850w would be enough, if you were running intel. Sadly you are running AMD. in all technicality, you can still run the system, but as the enthusiast community knows, its more than just watts. You see, there is a 12V rating and other voltage rails in the PSU, the 12V runs you GPU and CPU and (others) but your main concern is the GPU and CPU combined load, I would say dont go over 80% load with the GPU and CPU combined JUST on the 12V. SO your current PSU can supply 840watts max combined on the 12v rail, but thats saying that nothing else is hooked up. with everything else hooked up its safe to say that you've got 700 watts available on just the 12v rail, seeing as most 990fx boards will use around 70-90 watts. with only...

ANSWER:
Yes it will run, no it wont be a good idea for long term gaming sessions.

SOLUTION:
feel free to stick with corsair, when you look up the PSU look at the 12V rail specification. Multiply the VOLTAGE X AMP = WATTS and look for a PSU whose 12V wattage is above 950. that will allow you to safely run that CPU GPU and MOBO.

COMMENTS:
Also, you overclocked your CPU, which, with an 850W PSU would not be favorable, so unless you drop the FX back to 4.0 i wouldnt attempt on that PSU for the systems sake.

thats a beefy supply, you can get 1k watts with at least bronze certs much cheaper, you dont need them to be plats unles your overclocking ALOT. like GPU + CPU or if your pushing the ceiling power, lemme look
