No display on new build

[RianYT_2017]

Hello, I’ve recently [strike]got[/strike] built a new computer and was wandering why it doesn’t have any display at all. Everything turns on and powers up but no sign at all on the monitor

I’m new to building computers and have asked questions on here before

A couple more things that you should know...
I don’t have a GPU or and ram installed and only have my and ryzen 2700x installed with a wraith spire
I have 750w Corsair psu
And a Corsair gaming case
And last the motherboard
B350-F gaming motherboard

1, You have no gpu there wont be any display without one.
2, You have an old motherboard that will need a bios update before it supports the 2700x
3, You don't have RAM either? how do you expect it to actually work?
