Expanding the boundaries

Popular micro-ATX motherboards based on the B450 chipset look damn attractive. With an average check of $100, they offer a universal format suitable for both regular and compact cases, 4 slots for RAM and good overclocking capabilities. But ASRock B450M Pro4 goes even further.

USB-C, NVMe and gigabit LAN controller

It costs just $80, boasts a multi-phase Digi Power digital power subsystem and VRM cooling, a pair of M.2 slots (one NVMe and one SATA) and two full-length PCI-E 16x (although the second only provides x4). The board also has four DIMM slots (a maximum clock speed of 3200 MHz is supported), four regular SATA and modern USB-C, which is not so common in boards in this price segment. Of the pleasant, it is worth noting a gigabit LAN controller, 7-channel mid-range audio and support for AMD Crossfire-X.

Will pull AMD Ryzen 7 3700X

Considering the reinforced power circuits of the processor, even a powerful processor of the AMD Ryzen 7 3700X level can be installed in the ASRock B450M Pro4 and count on moderate overclocking without fear of overheating. In the Intel camp, for this money, you will be offered the most simple motherboards without VRM cooling, overclocking, or support for high-speed memory. The only thing is that before buying, check with the seller which version of the board you are offered. Models released before May 2019 will need a BIOS update to version 3.30 to add support for the new AMD Ryzen 3000. If you're buying a 2nd generation Ryzen processor, this doesn't matter.
