So I started a new PC build today (2nd build ever, first in about 4 years) and I seem to have run into a wall.

Specs: Asus ROG Strix z390-e LGA 1151, Asus rtx 270, i7-9700k, Trident Z RGB 16gb, Corsair RMX 850 80+ Gold, NZXT kraken and a NZXT h500i

So I finish putting everything together and the first thing I notice is that pressing the power button on the case doesn't do anything. The RGB lighting on the mobo (by the IO shield) works, as well as the two small lights on the GPU, where the cables connect. I have since pulled everything out of the case and tried to do everything out of the case, but still I get the same results. I have tried a different power supply, different ram configurations, no GPU, and tried re-seating the CPU. Same exact result every time, with the only sign of life being that the RGB lights on the mobo light up. I'd really appreciate any help on this one, pretty tired of pulling my hair out over it.

Do you have case PWR button cable plugged into the right header on the motherboard?

Yeah, all that is attached right. As the following post shows, the front I/O is one large connector as opposed to a bunch of smaller ones.

So when you press the power button nothing happens? Fans won't spin, drives won't start or anything? Have you tried shorting the power  pins on the motherboard with a screwdriver or something conductive to make sure its not your power button fault?

Exactly. The only sign of life is the RGB lighting on the mobo lights up as soon as I turn the power supply on, as well as two small lights on the gpu, but that is it. No fans, no other lights, nothing else. Yes, I've tried shorting the pins, but I haven't had much luck with that either
