Building my first PC

[Atomhearthero]

I am looking to build my first PC and at the moment I am having trouble picking parts. My budget is about 2500$

I am going to get MasterCase 5 Pro for sure 

For motherboard i am thinking about getting Asus Maximus VIII Hero Alpha or Asus Sabertooth z170 mark 1

Cpu-intel skylake i7 6700k 

Gpu-Asus matrix 980 ti platinum

For power supply I have no idea

Monitor-Acer XB270HU

I will use pc mostly for gaming.

What are you going to use it for?
If gaming what resolution?
Do you need peripherals?

Do you need any peripherals and what are you going to use it for

I already got mouse and keyboard. Planning to use my old monitor and eventually get Acer HB270HU

Definitely go with a Corsair or EVGA PSU.  You definitely have the budget for it

Thanks guys for quick response! I will consider all your recommendations. I was thinking getting Asus matrix 980 Ti platinum and eventually get another one. Is it worth consideration ?
