You can't update the BIOS on most motherboards without a CPU. That CPU requires BIOS 505 which was released in January 2014. You are probably OK to just assemble it and THEN update to the most current (2204) BIOS.

DO NOT upgrade a bios unless the update will fix a problem that is impacting you.
A failed bios update can permanently brick your motherboard.

A motherboard will come with the most recent bios version at the time of manufacture. You will be fine unless you bought some very outdated stock.
Go ahead and assemble. The bios screen will tell you what your current bios level is.

Then, if you want, you can look at the asus support page and see if there are any later versions and what the update fixes.
