450w CXM would be more than enough for this build (you can replace it to save some cash)
but i threw in 550w just in case you decide to add some gaming video card in the future .
even some video editing programs can benefit from nvidia gtx cards .
you could also build your system around ryzen 1700x which is 8 cores 16 threads cpu and it can be overclocked
( i7 8700 has 6 cores and 12 threads total )
but ryzen doesn´t have integrated graphics card so you would have to spend additional money on dedicated video card
(at least nvidia gt 1030 which costs around 100 AUD) .
