There you have it, our top B350 motherboard picks. Before wrapping things up please note that almost all B350 motherboards are designed and capable of safely powering an 8-core/16-thread Ryzen 7 CPU such as the 1800X. In fact, the only board we know of that can't is the Asrock AB350M-HDV, which is listed as being compatible with 65W Ryzen CPUs, so while you could install a Ryzen 7 1700, you certainly shouldn't overclock it on that particular board. It's an interesting choice Asrock made with the AB350M-HDV as the plainer sounding AB350M is so much better.
When buying a more premium B350 board be aware that good quality X370 boards start at around $130, so you're generally going to spend at least $20 to $30 more on an X370 board of comparable quality.
The X370 chipset provides four extra USB 3.1 Gen1 ports and two extra SATA 6 Gbps ports thanks to the inclusion of two extra PCIe 2.0 lanes. It also supports multiple GPUs using a dual x8 configuration. For most users, the X370 boards offer very little over the B350-based models, which is why B350 motherboards are so popular.
