First attempt at a PC build and would like a second opinion

[Spac3Ranger]

Hey guys

This is my very first attempt ever to build a gaming PC and I would love to hear what you have to say about it - both good and bad.
I will be using it primarily for gaming, mostly Dota2 and CS GO but also more heavy stuff like FarCry and Shadow of Mordor.
Besides gaming, I'm hoping to use it for some game development and video editing.

But please, let me hear what you think. I am especially in doubt regarding the power supply. Not sure if I have too much or not enough watt?

Thank you in advance

Looks good. Intel's SSDs are maybe a bit pricey, as is the motherboard (unless you really want WiFi). That's about all I have to say.
