Motherboard doesn’t turn on

[Fredster5000]

So guys,

my first pc build didnt turn on, so i took apart everything, i just have the motherboard connected to the PSU,

however, when i turn the PSU on, the motherboard flashes but doesn’t stay on, does that mean its broken?

What mobo and psu?

[LukeSavenije]

and any pattern in the flashing? do you have a little speaker connected to it?

[Fredster5000]

PSU is EVGA 750W G2

MOBO is Z390 Aorus pro Wi-Fi 

[Fredster5000]

Every slot just flashes, nothing remains turn on

The mobo will not post without a cpu, ram, and storage. (some mobos require a gpu)

[Fredster5000]

Ok thanks

im guessing it did it with nothing in it

[Fredster5000]

This is what it did

[LukeSavenije]

what if you put in the cpu and ram?

[Fredster5000]

Anyways, do i also have to power the cpu etc? Or can i just connect only the mobo to the psu?

nope. the memory and cpu should be enough to get into the bios. add your hdd or ssd for the os if you want to go to that step. but first, bios time

well, forget to say one thing. add a cooler

[Fredster5000]

But it should turn on without cooler right?

[LukeSavenije]

btw, this might be a psu problem. I'm adding @seon123 and @Stefan Payne here.
