I recently upgraded my setup with a new AM5 Motherboard (Asus TUF Gaming B650 Plus WiFi), a Ryzen 5 7600X CPU, and two 16 GB DDR5 RAM sticks. After turning off my PC and changing everything out, I reassembled it in my NZXT H6 case. However, now my tower won't turn on at all. The front panel button, which normally glows white, is completely off. When I plug my mouse into the motherboard, its RGB lights up, but my keyboard doesn't respond. I'm using a 750W power supply along with an Nvidia 3070. I even tested the power supply with a paper clip, and the fan worked fine, so I know it has power. What's going on?

It’s good that you unplugged the PSU while swapping parts, but just to be safe, did you ensure the rear switch on the PSU was off before you started? This prevents any residual power. If the motherboard is getting some power (since your mouse RGB lights up), there might still be a power delivery issue. Try removing components one by one to see if the system responds after removing anything, starting with the RAM.
First off, make sure the power cable from the wall is firmly connected to your power supply. It might sound simple, but it’s an easy oversight! Also, double-check that all of your components are seated correctly. Sometimes, reseating them can help. Did you connect the front panel connectors properly to the motherboard? That’s essential for the power button to work right. If those are good and the power supply is functional, we might need to look deeper into other issues.
