Need to know if my setup is good enough for a 1080.

I finally decided it is time for me to sell my 970 and get a 1080 (I upgraded my monitor and now it's time to upgrade the GPU as well)
I did my research, I'm not completely nuts, but I'd still like an opinion about whether stuff is going to bottleneck and/or if my power supply is insufficient.

My setup is:
Core I7 4790k @ default clock speeds
Corsair dominator 16GB of RAM
Corsair RM650 (as a side note only two good power supply companies available in my area are Corsair and CoolerMaster)

I calculated the power here:
http://www.coolermaster.com/power-supply-calculator/
http://outervision.com/power-supply-calculator
and they both recommended me a 550W power supply. I personally think it's BS which is why I came here.

Both Cooler Master and Outervision calculators suck eggs. Cooler Master overexaggerates so you spend extra money on a high-qattage Cooler Master PSU when you don't need to. Outervision just overestimates like crazy.

Want to know your real power requirements?

An aftermarket GTX 1080 and and your I7 CPU at stock clocks should be around 275W when gaming with Vsync off, or less even if Vsync is on with a stable 60FPS. Under max load, your system should not even surpass 325W. With overclocking of the CPU and GPU, gaming load will probably increase to around 315W and max load more like 375W-400W.

Thanks, this takes a big one off my chest knowing I don't have to spend anything for a new power supply.
