Question Case / Motherboard / PSU not too sure which is the problem. Help please?

[MLopez156]

System specs:
Asus Z690-Plus D4
Intel 12700K
GTX 1080 (for now, waiting for new GPU's to launch)
Gigabyte 1000W Gold+ Modular PSU

My issue baffles me. I set everything up, and the motherboard lights up, but when I press the power button on the case, fans dont spin, and the RGB on the fans, don't light up. My GPU's dont light up either when they're plugged into the PSU, which is why I suspected the PSU. I'm hoping you guys could help me troubleshoot, or peg the problem. I just got the components yesterday, so I didn't think they could be faulty, and I've chalked it up to my own negligence. But the more I stare at it and watch videos, the more I realized I plugged everything in correctly, I mean I followed the instructions carefully. The case as well. So I thought the case wiring might be faulty. I've built a PC before (granted it was like 2013), so I'm not 100% new to this. I'm not too sure how to troubleshoot the case, I've read that I could use the paperclip trick to check the PSU.

There's no power switch on the motherboard, so I can't circumvent the case power switch to turn on the system to check.

Case power button/front panel connected to the motherboard?

Yes! I connected the POWER SW+- directly to the motherboard, where the motherboard's instructions led me to plug it in. I made sure I connected everything, including the power sata connector for the case fans, directly to the PSU.

Your case fans: what are they? Maker and model. IF they have TWO connectors of different sizes on the end of their cables, tell us that. That kind of fan cables can be misused and cause this.
