How much power will a oc'd i5 4670k and 780 take?

[Ves]

I'm putting together a build for my computer and I'm wondering if the SeaSonic 650-Watt ATX 80 PLUS GOLD would be enough for it as it is costs $75 on Amazon.
I'm planning on overclocking the cpu to 4.4ghz and the gpu clock speed to 1050 mhz.
Here is my build for it.

4670K uses about 150W at 4.6Ghz, 770 uses 185-200W. Seasonic 650W would be fine
