Hi YASH SHAH,
I would suggest to get much more powerful power supply 650-750 W. Because in future you what a nice graphics card, which will require a bit of power.
I'm not sure if you already have a case. If not, carefully pay attention to a good air flow, check for dimensions so it can fit your CPU cooler height and future graphics card length.
And like guys suggested 2 x 8GB RAM will be much better choice.
Good luck with your build!
