Noisy PSU - Is 430W enough for my PC?

My PSU gets really noisy at random times, I'm going to assume it's faulty and return it but wanted to check if I should replace it or upgrade to more power. I'm calculating the below to be no more than 300W, and I only use it for general use, internet, torrents etc not gaming or video editing etc.

AMD A8 5600K Black Edition CPU (100W?)

MSI A55M-E33 FM2+ Motherboard (75W?)
