Problem:
New build, pressing start button does nothing.

Hardware:
Asus prime ap201
TUF Gaming B650M plus WiFi
AMD 7800X3D
Arctic Liquid Freezer II 360
RX 580 8gb (reused)
NZXT C650 Gold
Samsung 970 Evo plus
2x Corsair Vengeance 16gb 5600mhz

What I know:
Front IO is working
Rear USB is working
GPU LED turns red without direct PSU power and white with power
No LEDs on the motherboard (but I cant find any info about it in the manual besides the qLed but no power indicator)

What I've tried:
Swapping PSU from old working system (Corsair RM650x)
Swapping CMOS from old system
Jumping the starter switch header
Reseating RAM and swapping positions


I don't know what else to try.. Everything seems to be getting power just fine...

Yes I meant I swapped the batteries from both systems. And I've tried booting with and without GPU without success. Currently in the process of using their FlashBack feature to flash the newest BIOS version.
