Need psu for new ITX build

[NoodleFish]

So I've recently decided on building a mini-itx PC.

Here are the components:

Cpu: i7 8700

Mobo: Asus rog strix b360 i

Gpu: GTX 1080 gigabyte mini 

Ram: 16gb of ddr4 corsair vengeance LX

Case:Bitfenix prodigy m

Psu:Corsair sf450?

 

Here's the thing. I am uncertain if the 450 watts would be plenty for this build. Since it will be a locked CPU and GPU, no overclocking will be done.

 

Thoughts?

450 W is enough without OC.
