Are these parts all compatible and what should I upgrade?

Hello, I am a first time builder that needs some help. I want to build a gaming PC that runs most games at atleast medium, and I need to know if these parts are compatible with eachother. I also need to know which parts I should swap out. I already have a monitor and OS, so that's out of the way!  
First, here is some info that might help:

My budget is about 650 dollars and I buy everything from newegg.

I want to stick to Intel CPU's and Intel compatible mobos, since I was gonna go for an i3 CPU.

I am not planning to overclock.

My monitor size is 1920x1200. I know that the video card I chose doesn't support that resolution, but I chose it because I was planning to upgrade it later (I am open to some recommendations for other video card anyway   ).

Now, I know my Power Supply is not the best, so I wanna know what I should get instead.


Now to the parts I currently have planned to purchase and put together into a medium gaming rig.
