Why won’t my pc boot up

[joshuabracy]

Hi so I have all of my parts
Case: nzxt s340
Mb: gigabyte gaming AB350
CPU: AMD Ryzen 5 1500
Psu: seasonic 620w
Ram: Corsair 3k ddr4
Ssd: Sandisk ultra 250gb

I am waiting on my graphics card to be delivered but when I try to boot up to install my OS and drivers nothing happens when I turn the power on and hitting the power button does nothing
The power button does light up so I know that it is at least getting power

Ryzen does not have integrated graphics so you need to have a GPU installed to get monitor signal and install OS and drivers
