Your CPU will fit on your motherboard. The Cryorig H7 is a good choice. The Gammax 400 is another.
The size of PSU you need will depend also on your graphics card. If none, a good but inexpensive Seasonic 300W 80+ Bronze PSU would do. If you're going to run a high powered gaming graphics card, you might need a similarly high-quality 650W unit, so there's quite a range there.
