Question Heard a loud pop followed by electrical smoke smell -- now have a red cpu light and no boot ?

Hadn't turned my pc on in a little over a week. then turned it on and went to plug a printer into the front usb. As soon as usb made contact with the port I heard a loud pop and smelled electrical smoke. Immediately turned pc off, powersupply off and then unplugged and let sit for the night.
Next day no boot. Red cpu light on mobo is on. all fans spin up graphics card lights and fans come on. rgb lighting on mobo turns on as well.

I've tried using a different cpu and reseating ram.

I have a spare mobo, cpu, set of ram, and graphics card. I dont wont to keep swapping parts in fear that I fry a good backup.

Specs:
Asus TUF X570 Pro mobo
AMD Ryzen 7 5800x
Corsair h100 cooler
Corsair 650w PSU
2x 16gb Gskill DDR4 3600
Gigabyte RTX 3070

Spares
Gigabyte B550 Mobo
AMD Ryzen 5 3600
RTX 2060
2x 8gb DDR4 3600

All spares worked last time they were used but it has been 1+ years for all of it.

Corsair 650w PSU
Corsair is the brand of the PSU while 650W is the advertised wattage for the unit. What is the model of the unit? How old is said unit?

Spares
So you're using the older PSU?
