My First PC Build Plan

[acosma]

I have decided to build a pc around my already purchased GPU:GIGABYTE GTX970 G1 Gaming.
I don't aim for OC nor SLI/CrossFire configurations.
Here is the list with my choice of components:

Motherboard==>GIGABYTE GA-H270M-D3H
Processor==>Intel Kaby Lake, Core i5 7600 3.50GHz
RAM==>HyperX Fury Black 16GB DDR4 2133MHz CL14 Dual Channel Kit
SSD==>HyperX FURY 120GB SATA-III 2.5 inch
HDD==>WD Blue 1TB SATA-III 7200 RPM 64MB
PSU==>Seasonic S12II-620 Bronze 620W
Case==>Corsair Air 240 MicroATX Mid Tower Case

I would like to know if this build will work and if there is something that i can change in it.
Bear in mind that i aim for Price/Performance!
I would mostly like a recommendation of a stable PSU that can run my build and eventual future upgrades such as GPU.
Thank you!

Why did you go with an old GPU when there's plenty that are new and cheaper

I would assume the OP has had it for a little while, not that they JUST bought it.

@OP: Build looks pretty solid. Only thing I would change is the SSD drive. Kingston HyperX uses the blah Toshiba TLC chips that are not that much faster then a magnetic. Stick with Samsung or Crucial for SSD drives.
