I am planning to overclock this new pc build to around 4GHz - 4.2GHz, will my 550w PSU be enough? Here is the list of my build parts: https://uk.pcpartpicker.com/list/Nmbbyf
Thanks for the answers, the purpose of this build is for streaming and gaming, hence I couldn't go for the i3 core, I am planning to upgrade my GPU to the 1050 ti listed (currently running a 750ti on my old pc which I will put into this new build until I upgrade the new GTX)
