Built new pc, doesn't turn on, even though the motherboard has power.

[broklond]

Hello!

 

I just built my first system, all new parts, but it doesn't do anything when I press the power button.

The system is not complete, graphics card hasn't arrived yet, but here's the parts list:

CPU: Ryzen 5 3600

Mobo: Asus Prime X470 pro

RAM: G.Skill Trident-Z Royal 3000Mhz cl16 2x8GB

Storage: Kingston a2000 1TB m.2 nvme ssd

PSU: Corsair RM 650x

Case: Lian-Li Lancool 2

 

I just wanted to testboot the parts that I already have, because there are some parts that are closing in on their 1 month after purchase. The motherboard is sure getting power, because the rgb lights up as soon as I flip on the psu. I tried reconnecting the powerswitch connector every way, also tried shorting out the pins, didn't work. Reconnected the power cables, reseated the ram sticks, didn't work. As a last resort I pulled the graphics card from my flatmates pc and put it in my rig, still didn't work. Might be worth to note that the mobo was an OEM part.

I have three possibilities in mind:

1. The mobo has a case of DOA

2. maybethe cmos battery is dead.

3. The board might have been sitting in the sellers storage since before the bios updates, so the bios might not have been flashed to support ryzen 3000 series (though i don't know if that could cause a no power on).

Please, help me out!

i think this processor needs a grafics card to display something, so... look for someone who can lend you one maybe, till yours comes

My problem is that the mobo doesn't even turn on (fans don't spin, ram rgb doesn't light up, nothing), not that i don't have any display.

is your powerbutton connected correctly? ..  or broken.. try detatching it and short the two pins shortly to see if it boots. 

ah no you already did that.. 

it should boot anyway if cmos battery is dead.. just not remember any setting when you remove the power cord.

tried another psu? ..

Haven't tried another psu, I could only try my flatmates unit, but that would mean almost completely disassembling it. Although, the mobo has power, so I don't think the issue is with the psu.

Thanks for the answer, you at least debunked one of my concerns.
