I have a 450W (Corsair CX5450M Bronze) psu but will i need a new one?

I have:
i7 6700k
Hyper 212 Evo
Asus 1060 3GB
MSi Krait 3X
16 GB Ram
250 GB SSD
1TB HDD
TP Link wireless card
H440 Case (4 fans + fan hub)

And I'm thinking of upgrading to:
Corsair Watercooler for cpu (and overclock cpu)
NZXT Grid for better fan control
Add another 16GB ram

Will I need a better/bigger psu and which one would you recommend (semi modular/modular)
Note: Is this a good one? http://www.newegg.com/Product/Product.aspx?item=N82E16817139060

Is 450 not enough and also would 650 be overkill (even if it is the same price of 550 rn)?
