Introduction Today we have a new AMD B650 chipset-based motherboard for review, the ASRock B650 Pro RS socket AM5 motherboard.  This is a new, budget-conscious, DDR5 motherboard from ASRock based on AMD’s B650 chipset.  Currently, you can find this motherboard for $213 on Amazon and Newegg. The ASRock B650 Pro RS is based on AMD’s new B650 chipset, which as we have seen from our testing is no slouch, though it is on the lower end of AMD’s chipsets.  As with all of the AM5-based motherboards we have tested this motherboard also accepts DDR5 memory, and any AM5 chip released.
