The 4790k has about 34W higher TDP than the 4130. With your current build you have a ball park estimated load wattage of about 236W (

I'd suggest a 500-650W power supply for the sake of leaving yourself some head room for future expansion, since I assume you'll be upgrading to a better GPU in the near future. You can find tons of perfectly capable power supplies at or above those wattages for fairly low prices.
As for a CPU cooler, I always recommend a Hyper T4 or 212 EVO as a baseline. The T4 is about $20 and the 212 EVO is about $30. Both will work just fine on a 4790k unless you plan on overclocking it above 4.4GHz, in which case you'd want some sort of expanded/dual-sink cooler like a TC14PE or a D14... but that's for another discussion.
