A 450W power supply should be enough, but that's not a great quality unit... it's based on a pretty old design.
I'd recommend going with a Corsair CX450M for that build
Yes, but review shows it is decent for the price and no major hiccups: https://www.tomshardware.com/reviews/evga-450-bt-value-psu,5605.html
From EVGA, it's max power output is rated at 30C. That doesn't sound so promising to me.
