So I just finished new build and I dont have my cpu yet, but it should still turn on. When I went to the power supply I flipped the switch in the back a and the motherboard flashes. When I hit the power button, nothing. What's funny is that the USB on my case works but the fans on the case, power supply, GPU fan, and rgb is static. Plz help me.
Parts:
Cpu: none yet
Gpu: Radeon rx 580 (XFX)
Motherboard: Gigabyte Aorus B550 Elite
Power supply: EVGA Supernova 650w fully modular 80 plus gold
