Im planning on buying parts and building (my first) pc. Here are the parts:

AMD FX-8350
Cooler Master Hyper 212 EVO
Gigabyte GA-990XA-UD3
Corsair Vengeance 16GB (2 x 8GB) DDR3-1600
Samsung 840 Series 120GB
HDD: WD10EZEX (already have)
WD10EARS(already have)
Gigabyte GeForce GTX 660
Fractal Design Core 3000
Lite-On iHAS124 (already have)
and probably 2 more fans for case

And some day ill SLI the gtx 660

How much power do i really need after I OC the processor and graphics card(s).
pcpartpicker.com estimates 543W.
So should i buy a 550 W psu or more?
I live in europe so I can get the Corsair VS650 for really cheap.

Should i get it? Will it be good enough since its not really a gaming psu?

P.S.
Comments/Suggestions on build appreciated.
 
Solution
I agree with Goodeggray
a corsair vs 650 would be very sufficient
i have a 8350, and a gtx 670 as of yesterday i havent gone over 400 watts
im also over clocked to 4.8 ghz
