You have DDR3 memory selected, however your motherboard and CPU require DDR4 memory. They're not compatible with each other.
You don't need a 750W PSU. Get a Corsair CX450M instead.

Edit: Here's a PCPartPicker list with the RAM and PSU fixed.

You could save a bit of money by changing to a different motherboard. You're really paying a premium price for the wifi versions. If you don't need wifi, or you have a PCIe wifi network card, then you can save $30+ by swapping motherboards.

Not sure what these both mean, since a b250 does not work with an 8th gen processor. and b250 is not really related to b360 except that it is its predecessor.

You'll need ddr4 for new CPUs, not ddr3.

 

It's good that you selected a non-overclock CPU and a mid tier motherboard, I see lots of people going for a high end mobo with non-overclockable CPUs

GIGABYTE b350 aorus gaming wifi is a fine choice, quite a good board IMO. Also, what power supply did you select exactly?
