[SOLVED] No display from new pc build, potentially bad mobo?

[Snoopdragon20]

Specs:
CPU: amd ryzen 7 5800x
Power supply: evga 750gt 80plus gold
RAM: gold key 32gb (2x16) ddr4
SSD: Samsung 970 evo NVMe M.2
Motherboard: asus rog strix b450-f gaming
GPU: power color radeon 550 (temporary until a new card is purchasable)

I cannot get the computer to post to bios or any display at all. Upon powering, all fans spin as normal, the motherboard has a constant amber light, but does not beep at all. A different graphics card that is known to work (gtx 970)has been used and has the same result. I have went down the no display checklist (tried 1 and both sticks of ram in every configuration, reset the cmos, motherboard is properly stood off from case, etc). With no RAM and with no memory at all the motherboard still will not beep under any circumstance. The motherboard speaker is known to work on other boards. Display port and hdmi cables that are known to work have both been tested. Anti static straps were worn during the entire assembly process. Is this possibly a faulty motherboard?Any help is appreciated.

So far as I am aware the 450 motherboards don't have BIOS revisions to run 5xxx Ryzen yet. You will either need a 5xx motherboard, or a 3xxx CPU for the time being.

Unless your B450 motherboard was manufactured recently where they already added the BIOS update and your motherboard box has a sticker "Ryzen 5000 ready" you will have to update the BIOS of your motherboard to support the 5800X.

You can:

• Go to a local store so they BIOS update your board for you
• Lend a CPU from AMD that you have to return - https://www.amd.com/en/support/kb/faq/pa-100#faq-Short-Term-Processor-Loan-Boot-Kit
• Buy a CPU supported by your board to flash the BIOS and install the new CPU.

Thank you both so much! Sounds like I'll need to take my board back in to either be updated or exchanged. I'll do that tomorrow, try the build again, and update. You all were very helpful

Update:
You guys were right, issue with the bios update. Exchanged the mobo for a "ryzen 5000 ready" one (b550-f) and we got the bios screen upon booting. Thank you!!!
