I recently built a new pc and from the first time I started up the PC I had to press the power button 3 times to power up the PC. I emailed the case manufacturer and they sent me a new button but that did not change anything. Now a month later I still have the power button problem but my computer has started shutting down randomly and when I press the power button the computer turns on for a brief second Everytime I press the power button but does not turn back on.

Windows 10 home, i5 8400, msi z370 gaming m5, evga gtx 1080 ftw2, 16gb g.skill trident, Corsair rm750i, phanteks enthoo evolv case

With it running, have you inspected the temps using either the BIOS or something like HWMonitor?

Describe in more detail what happens the first two times you press the power button, please?

I suspect either the power supply or the system board; but, need more details...

When I press the power button the first two times all my lights on my mobo and GPU turn on and the fans start spinning. If I don't press it the third time everything shuts off. but not until I press the third time does it actually power on

It's actually turning on the first two times; but, for some reason thinks it needs to shutdown again.  The most likely culprits are the power supply or the system board.  Can you or have you tried another power supply?

I contacted my psu manufacturer and they are sending me a replacement. Hopefully that fixes it. If not I'll swap the board

I think you should also check its power button connection and the power assembly of your motherboard. It looks strange that the three times of button push will turn on the PC.

He already replaced the power button assembly and the PC does turn on (fans spin, lights turn on) the first two times he pushes the button.
