Ga-h270n-wifi wont power on.

I have a picopsu 150xt and an i5 7600k in it. I plug in the brick, hit the power button, and.... Nothing. No fans, no lights (except the power button). This isn't my first build either. Cooler is properly seated, CPU and ATX power plugged in, cpu fan plugged in, ram seated properly, etc.

You're only pushing 150w on to the system, so first I gotta ask if you have enough plugged in to the system that it's not getting enough power? Always start with bare minimum when testing your build and slowly add part by part.

Second, do you have access to a normal ATX PSU? I've had bad picopsu units in the past, so I'd double check that it's not your unit thats faulty.

People on the sff forum have ran an i7 and a gtx 1060 on 160w. It's enough power. I tried it with a corsair PSU and it still wouldn't boot.

motherboard manual - page 14

To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

Another brand - Asus recommends a minimum of 350 watts for the PRIME H270-PR0.

Damn, that board doesn't have any diagnostic lights or Qcode screens. Do you have an internal speaker hooked on so you can get diganostic beeps?

When in doubt, always clear the bios just in case. From there, do a tear down and carefully inspect for bent pins on the CPU, clean/remount the CPU cooler, install only CPU and RAM and run with bare min configuration. Also, and it's an easy one to miss, make sure you're putting the power button front header on right. You can short it with a screw driver to bypass the power button on the case. I've had an entire built not work from a faulty button on the case, and took me forever to figure out.

Okay. So, i unplugged the vandal switch i was using, and it booted. :/ i guess it was the switch.

Well at least it was a simple switch issue and not a core component.
