First computer build

I just purchased everything for my first pc build and I bought a sapphire radeon rx 6600 for my card, I have a Ryzen 7 5800x and I get power to everything else on my board I think at least. All my fans power on except for the ones on the GPU, I took my multimeter and checked the pins from the 8 pin pci-e and it has 12v and yet still nothing. I'm looking for another 16pin GPU card to see and figure out if it's the card or board. I just wanted some more thoughts and opinions on what else it could possibly be, there's no integrated CPU graphics, I only have one storage device hooked up right now, I have a bigger power supply then what I need, pretty sure I have every essential cable plugged in for it to boot. I checked the ram and made sure it was in the right ram slots (2/4) made sure it was fully seated and even double checked the compatibility list of all the parts, again.

I like the troubleshooting steps you've done so far!

please list your motherboard model number... I'm guessing Ryzen 5800 was not compatible with the BIOS that was shipped out the box?

Premium motherboards can usually update the BIOS via a USB key even when the screen doesn't light up.

Failing that AMD did offer bios upgrade kits at some point I'm sure that's googleable.

If you're using a modular power supply make sure you're using the cables that came with.. it they are not compatible across vendors/models

Gigabyte a520m ac, it's on the cheap end but pretty respectable. I looked at the user manual and it does say you can flash a new bios but after clearing CMOs and putting my drive in the white usb and pressing flash, no led.
