Z270 boards do not support 8000 series cpu, you need a Z370 motherboard.
Please list all your components so we can be sure that is the issue.

Just installed an Intell i7-8700 and 2 sticks of PNY 8GB DDR4 2133Mhz.  Nothing else installed yet.  When I hit the I/O button on the PS the white/bluish led under the black and white ASRock heat sink comes on and pulses.  It then turns red and pulses.  Pressing the power button has no effect; not even the power supply fan.

My case doesn't have a speaker, although I would guess since it won't even power that wouldn't help.  The manual has no troubleshooting section that I can find to determine if the colored LEDs have meaning.

I must have built 50 systems, and usually if they won't boot (which is rare) I triple check all connections.  Did that a few times - they're all good.  Then pull the CMOS battery.  No luck.  Even disconnect the power and jump the clear CMOS jumpers.  Still no luck.

I think I've only had 1 DOA MB in all those builds - usually there is something in the manual. 

Any help is appreciated.
