Question PC won’t boot.

[nonoarred]

I am a first time PC builder and I put everything together. All my components are compatible, and I triple checked everything was connected correctly. When I went to turn on my pc for the first time nothing turned on, the fans, aio pump, or ram rgbs. I’m almost certain my motherboard is not fried as I do not have carpet in my house, I was wearing clothes that wouldn’t create static, and I would constantly ground myself using the case. I just don’t understand what could possibly be wrong here. If someone could help me out that would be great thanks!

Did you try PSU paperclip test? Is there AC voltage at the other end of the mains cable that plugs into the PSU? I faced similar issue. In my situation it was the issue with the extension box and the old cable that I was using.
