New PC booting when PSU is turned on

[jrh0067]

My specs: https://pcpartpicker.com/list/9tk7sp

As the title said, my PC is automatically booting when I flip my PSU switch on. This doesn't really matter long term because I'll always have the PSU on, but since I've just built my new PC and have been doing some troubleshooting, I've noticed that it started doing this.

It didn't always do this, but at some point after installing Windows/ other programs/ doing generic new PC stuff, it started doing this every single time I flip that switch on.

Any ideas of what may be causing this, and if it could cause issues?

Thanks.
