Power Button won't turn on the PC

[DiesHorribly]

I just recently finished assembling my first own PC and i run into a problem with the power button.
If I press the power button the PC turns on for about 2-3 seconds and then turns off again without reaching the POST screen.
I can turn it on though just fine by using the power switch on the MB itself. Tried to change the connectors but the problem is still there.

Specs:
MB: ASUS Z170-A
CPU: i5 6600k
GPU: EVGA GTX 980 S.C.
PSU: Corsair 650x
RAM: 2x Kingston 8GB

Could there be a problem with the button itself or something else?

Try removing the front case wires and starting the board by shortly touching with a screwdriver the 2 pins on the motherboard corresponding to the case power button. If working, then the case power button might be defective.

It starts up fine with the screwdriver!
The power button is a DimasTech power switch.

Does the front of your case have a reset button in addition to the power button? If so, try connecting the reset button wires to the power switch pins on the motherboard. If then depressing the reset button allows the computer to start, that would confirm the power button switch is bad.

Check again the wiring diagram. Make sure that it is properly connected.

Unfortunally there is no reset button. Its a custom build wall mounted pc.

How do i unselect the best solution? I accidentally pressed the button.

Do you or someone you know have a digital multimeter. If so you could touch the probes to the wires coming from the power switch and press the power switch to test for continuity.

Or you could go with one of these:

But if this is a brand new build, you probably don't want to resort to rigging things up so soon. But because they do sell this thing, that tells me there must be a need for it.

(Your thread is not showing up as solved)

From what I can see it should be wired correctly. Also tried all possible wiring configurations i can think of.
Stupid question: there are five connectors on the power switch! +, -, on, on and 0 but my cable only has 4 connectors! Could that be the problem?

Also the switch stays locked inside if I pusch it

Also the switch stays locked inside if I push it.
That's the problem. and therefore the restarts. You need a momentary switch.

Thanks alexoiu, i knew i made some rookie mistake.

I'll se if i can exchange it for an other one.

 

[alexoiu]

You're welcome.

Alexoiu is correct. Momentary switch is what you need. Since this is a wall mounted computer, you may want a external switch like I linked to above, so you can power on from your desk. It has power switch, reset button, led for power on and led for disk activity.

I'll lock into the external switch if i can't exchange this one for free. But thanks for the tip
