A very reasonable build.
I have some suggestions:
1. A single 8gb ram stick will run in slower single channel mode.
Do not plan on adding another later; it may be incompatible.
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.
If 8gb is all you will ever want, buy a 2 x 4gb kit.
Ram is not that expensive, aand I suggest you buy your 16gb kit up front.
1.2v ddr4 2400 speed is fine.
2. Love a ssd for windows.
But, do yourself a favor and buy Samsung 850 evo. they cost a bit more, but perform better and last longer. 5 years warranty vs. 3.
3. That is not one of the better evga power supplies.

This Seasonic S12II 520w unit is stronger, cheaper, and is tier 2:

Since you will be using the intel stock cooler(entirely adequate), here is my canned instructions on how to mount it:
----------------how to mount the stock Intel cooler--------------
The stock Intel cooler can be tricky to install.
A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.
To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise)
and pulled up as far as they can go.
Take the time to play with the pushpin mechanism until you know how they work.
Orient the 4 pins so that they are exactly over the motherboard holes.
If one is out of place, you will damage the pins which are delicate.
Push down on a DIAGONAL pair of pins at the same time. Then the other pair.
When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.
If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.
If you should need to remove the cooler, turn the pins counter clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.
