Despite the fact that AMD promised that $125 AM5 are coming, there aren't many such motherboards on the market. The newest addition is the Gigabyte B650M K, which is now available at $124.99. Gigabyte's B650M K will be joining the previously available ASRock B650M-HDV/M.2 microATX motherboard, which was the first B650-based motherboard available at $125.

Same as the ASRock motherboard, the Gigabyte B650M K is also a micro-ATX motherboard with the same 8+2+1 VRM, but features four DIMM slots with support for up to 128 GB of DDR5-6400+ memory. Unfortunately, it apparently features two PCIe 4.0 M.2 slots, rather than a PCIe 5.0 x4, and comes with a single PCI-Express 4.0 x16 slot (in addition to the PCIe 3.0 x1). The rest of the specifications include Realtek's Audio, Realtek 2.5 Gb Ethernet, couple of USB 3.2 Gen 2 Type-C, Type-A, and USB 2.0/1.1 ports, as well as DisplayPort 1.4 and HDMI 2.1 outputs. Bear in mind that both of these are $139.99 motherboards, discounted down to $124.99, so hopefully, we'll see more of these $124.99 motherboards soon.
 
This should help financially limited consumers when moving to an AM5 platform.
