I'm putting together a DDR4 PC featuring the Intel i7-14700K processor. So far, everything has been smooth, but I'm hitting a snag when it comes to selecting a motherboard. I came across the Gigabyte Z790 D DDR4 ATX LGA1700 motherboard, which seems to have a decent price and specifications. However, when I added it to my build on a parts tracking website, I received a warning stating that if the motherboard has an older BIOS version, I would need to update it to support my CPU. I'm wondering if I can do the BIOS update after my PC is fully assembled, or if I will have to use a different CPU to update the BIOS first. Any guidance, or suggestions for other motherboards that are in stock and compatible, would be greatly appreciated!

You can definitely update the BIOS without initially installing the CPU. The Gigabyte Z790 D has a feature called Q-Flash Plus that allows you to flash the BIOS even without a CPU installed. Just make sure you download the correct BIOS file from the manufacturer's website, format a USB stick to FAT32, and rename the BIOS file to GIGABYTE.bin before flashing it. It's not too complicated, but if you're unsure, it might be worth it to pay a local PC shop to do it for you.
To update the BIOS, you typically need a functional CPU, but some boards, including newer models, have the capability to update with just a USB drive, like others pointed out. Just ensure you're following the right steps for your specific motherboard—check the version to be compatible! Don't hesitate to reach out if you're unsure about any part of the process.
If you're shopping locally, ask the store to check if they can update the BIOS for you before you buy it. If you're ordering online, you'll just need a USB drive and access to another computer to carry out the BIOS update yourself. There are plenty of guides on YouTube that walk you through the process, so you’ll find it pretty straightforward.
Most new motherboards should be shipping with updated BIOS, especially if they haven't been sitting around for too long. Check the details online, as some retailers will even mention if the BIOS is current. But it’s always good to confirm before you make your purchase!
