Building a new setup for mojave (hopefully) questions about compatibility.

So i have purchased an intel core I5 9600k and a MPG Z390 GAMING PLUS motherboard so far.

I am planning on buying Sapphire Radeon Pulse RX 580 video card and I already have 16gb of ddr4 ram.(not sure of brand)

As well as I already have a psu also not sure of brand or wattage.

I am curious as to what my chances are of getting of getting an install done on that motherboard and cpu as i cant seem to find much info for installing on z390 boards.

Any advise as to installation would be greatly appreciated!

Thanks!
