Some PSU's run completely fanless when they are under 30-40% load, I love that about my EVGA 850G2, while I'm doing light gaming or web browsing, i don't hear my system at all.

You should be completely fine. As others mentioned you're probably somewhere in the 750w range or so under full load. If you really want to be absolutely sure you could grab a Kill-a-watt meter and verify what the machine is pulling at the wall: http://www.newegg.com/Product/Product.aspx?Item=9SIA24G0P60122&cm_re=kill_a_watt-_-82-715-001-_-Product

^ really useful thing to have around imo. Just remember that your PSU's rating is the amount of power it can deliver to the components continuously. Assuming it is something like 90% efficient, 1000w of delivery to components would be just over 1100w at the wall due to losses in the power supply itself.

Stop posting. If you're just going to argue with the people you asked a question to, then don't post.

The intel you are running is probably getting close to using as much power as my FX-9590 is (8 cores 4.9 Ghz 220-240 watts).
Just guessing but I think my mobo is using up about 90 watts when everything is going full tilt boogey. I am not sure what the power efficientcy is with your mobo VRs. Should be close to the same.
Now that the pwr supply has aged some I had to back off on the OC of the Crossfired 285/380 set. I was doing 1010 Mhz on each and have backed it down to 990. That is because of screen fails after about 20-30 minutes of gaming. With one monitor at 2560 x 1440. Running a 2 1/2 year old Cougar 1050. As far as 3Dmark goes, it does fine @ 1020 Mhz on both cards.
I also am running two pumps in a parallel loop, along with 12 fans.
I also have 8 devices plugged in to USB and use it too charge my cell phone. All them little things add up.
Should be good until the next fancy dancey number cruncher system comes along.
Another words it will work and maybe you could squeak a 295 for crossfire in too, if ya slow the intel CPU down a bit for a while. (like using close to the out of box speeds).
So yours will most likely be different than mine.

I am a firm believer that the power supply gets tired and looses 10-20% after about 2 years of constant use. Besides I don't crack em open and clean them until after the warranty expires. That & the keyboard is about the only use I have for a dust can.
