Motherboard: Asus Prime b450 plus
GPU: XFX Radeon RX 480
CPU: Ryzen 5 5600
PSU: Corsair TX650M, 650W PSU
A Samsung 1tb SSD

That's what I remember off the top of my head.
Did this rig work with a previous GPU? Your motherboard requires a BIOS update (3211 or newer) to use the 5000 series CPU.

The old FX is of no use. Connecting directly to the motherboard video headers won't work as the CPU lacks an integrated GPU (only those models ending in G have those).

You need a compatible CPU installed in your motherboard in order to update the BIOS for the 5600 to work.

From where did you purchase the motherboard?
