550M Phantom Gaming not booting

ASRock B550M Phantom Gaming 4

AMD Ryzen 5 5600 X

EVGA Supernova 550 GT 80 Plus Gold 550W

Teamgroup 32 GB DDR4 RAM

Teamgroup 1 TB NVME SSD

XFX 570 8GB



I put all my parts together. Upon pressing the power button lights turn on and fans spin. The box to my motherboard says Ryzen 5000 ready.



Everything powers on but there is no display on the monitor. No option to enter BIOS.



I checked connectors. I am thinking the motherboard shouldn't need a BIOS update since they put the sticker on the box.



I am letting the computer run on for a few minutes, but I do not know if I will ever get a boot screen.



Does anyone have any suggestions?

eccential wrote: I know this is unlikely, but you are connecting the monitor to the XFX 570 8GB, rather than to the motherboard's output, right? 5600X doesn't have an iGPU, so.... And make sure 8-pin 12V for the CPU and another 6/8-pin for the GPU is connected. Does the motherboard have any debug LEDs to indicate where in the boot process it's in? No other ideas.

Yes, I connected HDMI to the GPU.

There are no debug lights.

I already sent the motherboard back to Amazon.
