I would get a quality PSU from a trusted brand that has a 80+ Power Efficiency rating. The Cooler Master MWE 80+ Bronze 450w power supply shouldn't be good. It may have a bit more watts than needed, but it is better to get more just in case you want to upgrade in the future. If you don't worry about the cost, I would buy a modular power supply. They cost more but they offer more flexibility with the cables, which is a nice feature to have.

To choose a power supply, get one from a good brand, 80+ rating and more watts than you need.
Edit: your build generates around 300watts
