ASUS Prime B550M-K

ASUS’s cheapest B550 board is the B550M-K, which is almost identical to the B550M-A, with just fewer parts. The biggest visual difference is that the B550M-K does not come with a power delivery heatsink, with a simple 4+2 power delivery design.

This does make the board look a lot cleaner with its straight lines, however this isn’t going to be a board for pushing the boundaries. It has only two fan headers around the socket, has a smaller chipset heatsink, and is missing some of the headers on the bottom of the board, such as the one for Thunderbolt or RGB. The latter might be a good thing.

Users will still have a USB 3.0 header, two USB 2.0 headers, four SATA ports, a full PCIe 4.0 x16 slot, a PCIe 4.0 x4 M.2 slot for fast storage, and a PCIe 3.0 x4 M.2 slot from the chipset. Audio is the same ALC887 codec with some PCB separation.

On the rear panel the user will get a combination PS/2 port, four USB 3.2 Gen 1 ports, an analog D-Sub video output, a DVI-D video output, a HDMI video output, two USB 3.2 Gen 2 Type-A ports, a gigabit Ethernet port (Realtek RTL8111H), and the audio jacks.
