Is my power supply good enough for my build?

I just ordered a new GPU, but I am not entirely sure if my power supply is enough to run it.
My specs are:
- Intel i5 3570k 3,4 Ghz CPU
- XFX PRO 550 Watt power supply
- XFX Radeon R9 290 Black edition DD, 4GB GDDR5 GPU
My case also has a couple of LED fans, but don't think they draw too much power
I ran a calculation on the "Extreme" calculator, and it gave me a minimun requierment of 470 watts, but I am not sure how accurate that is.
The question is: Is my power supply enough?

That is fairly accurate to get the TDP of your PC during a full system stress test but nothing near the Watts that will be actually used during normal use like gaming.
Note what this PC is actually using while gaming in the above link.
With that said yes the 550 will work but I would actually go a bit higher. I like to run a full system stress test on eveery PC I build.
