Built a new pc and its not starting.

[techrookie39]

So i just built my new pc will all new parts.
Asus maximus x hero VIII z370 board.
Intel core i5-9600k
Kraken x52 240mm aio
16gb trident z ram
gtx 1080
650 w psu
1tb ssd and a nzxt h700i case.
The problem is that the board lights up but when i press the power switch it doesn't turn on my monitor so its still off? the aio and the ram don't have any light even though everything is connected.I disconnected the nzxt usb 2.0 connector from the board as even when it was connected it still didn't turn the aio cooler on.This is my first build and i'm sure i've connected everything properly so i have no clue why its not turning on.Any help would be appreciated and i'll leave the links with the photos of my pc. If i would need to update bios if that is the problem how would i do that if half of my components don't even turn on so obviously the monitor doesn't display anything aswell.

(One thing i forgot to mention is that i need an extra usb 2.0 port as i have 3 usb 2.0 cable and only 2 ports for them,but even with the 3 cables switched up it still doesn't work.)

Z370 boards and 9th gen CPU's work together, BUT the board needs a BIOS update to work with a 9th gen chip. It only can get the BIOS update when you put an 8th gen chip in the motherboard.
