I recently assembled a PC but it isn't powering up. Pay attention to this recording from 20230212_194818.mp4.

What you demonstrated in your video is a USB charger suitable for smartphones, not for powering a desktop computer. The reason you filmed it was likely to show how it works, but it doesn’t relate to your PC. You probably didn’t use the camera randomly to capture sound.
Yeah, I understand. And yes, I aimed my camera at something unexpected to capture the audio.
I barely catch what sounds like a fan spinning when headphones are on full volume. Usually you wouldn’t hear the PSU fan alongside other fans, so it’s possible you’re only noticing the PSU’s fan since nothing else is turning. Beyond that, if the machine won’t power up, it likely points to a power problem. It could be something minor like a faulty power switch or loose wiring, or more serious such as a failing PSU. Verify your 24-pin ATX, 4/8 pin CPU, and 6+2 PCIe power connections are properly seated, and carefully inspect the front panel header wiring—it’s easy to misplace a pin. A single missing pin will stop startup. There’s a video available on testing the PSU; I don’t suggest doing this while the board is connected.
