First time build, PSU wattage...

[crytech]

Hello guys, I am new at building a PC, so I'm looking for your help.
I'm going to use this machine mainly for gaming at 1080p, and some basic stuff...

There's no need to questioning my component choice, I am wondering how much wattage that I need for this build? According to PCPartPicker it's 188w, is it really that simple?
I am not going to Overclock.

I am going purchase a Corsair RM but I am wondering about which wattage I should choose...

Here's the build : http://pcpartpicker.com/p/mY6pzy

I am not denying the fact that I am going to upgrade this PC in the future, something like non-K i7 processor, a better GPU, more storage, and RAM.

A good 400 with 20 AMPs on the 12 VOLT rail will be more than enough, as is if thinking upgrading the GPU, what GPU will be the determining factor, a good 600 will take you up to a very high end single GPU setup

Does using 600 will cover my upgrade up in the future? you know, something like 4771, gtx 780ti, and 16gb of ram?

Yes, it will cover all and still have headroom, you'd be fine (even w/ a 4770K and OCing it) 😉
