Why won’t my Xbox Series X turn on?

6/21/24 I just replaced my power supply on my XSX and it still won’t turn on. Problem originated back in September of 23, I started playing a new game and the Xbox randomly shut off and never turned back on. I put the console on the shelf until I could work a replacement power supply into my budget, and I just got a new one installed into it. After installing the new power supply, the Xbox series x still won’t turn on. I even tried plugging the controller into the usb slot to turn it on that way and no luck. Any suggestions at to what the problem could be? I’m desperate…
