Question New PC not working

[VaxinAxis]

I’m currently making a PC for my local church and had everything plugged in, this is the first time I’ve turned it on ever and the fans turn on for the 30 seconds and it turns back off by itself and with no loading screen while a monitor is connected. I really need help.
Specs for the new computer:
Motherboard: Z490I AORUS ULTRA
GPU: NVIDIA GeForce GTX 1660 Super
CPU: 11th Gen Intel Core i5-11600KF
PSU: EVGA 600 GE 600w 80 plus gold
RAM: Team T-FORCE VULCAN Z 16GB (2 x 8GB) 288-Pin PC RAM DDR4 3200
Currently no CPU cooling fan or any disk drives connected, I’ve bought them and should arrive in a couple of days.

Never turn it on without a cooler.
