It looks like someone at ASUS put up wrong images for the wrong motherboard as its Z490 PRIME series for 10th Gen Intel Comet Lake Desktop CPUs has appeared on the product page for the Z390 PRIME series motherboard.

There are two motherboards that have been spotted by Momomo_US (Via Videocardz) which are the ASUS PRIME Z490-A and the ASUS PRIME Z490-P. Both of these motherboards are part of the PRIME series which is more of a legacy ASUS brand while gamers would most likely be interested in ASUS's ROG line of motherboards.
