The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Othersby Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM EST
Nearer the bottom of the ASRock product stack we get to the B550M-HDV, which is aimed at the more commercial pre-build markets and aims to offer what these markets might need. As a result it does away with the fancy styling and aims to give the bare essentials. That means no power delivery heatsinks, only two DRAM slots, no extra M.2, and only a 4-pin CPU power connector is needed.
The idea for these boards is that they will be put into systems that might be found in commercial units, like libraries, medical facilities, youth centers, that sort of thing. So there are only two fan headers around the socket for example. The power delivery is basic, we get a 4 phase design, and the two DRAM slots are still single side latched.
Moving clockwise around the board we get the 24-pin ATX power connector, a USB 3.0 header, and four SATA ports. The bottom of the board is the audio front panel header, a Clear CMOS header, a TPM header, a COM header, two USB 2.0 headers, another 4-pin fan header, and the front panel header.
The PCIe area consists of a single PCIe 4.0 x16 slot, without extra reinforcement. Beneath this is the PCIe 4.0 x4 M.2 slot from the processor, and underneath this is the chipset heatsink, which is the smallest chipset heatsink I’ve seen on B550 so far. On the left hand side of the board is the audio, where we have an updated ALC887 solution using PCB separation.
On the rear panel, we get two USB 2.0 ports, a combination PS/2 port, HDMI output, an analog D-sub video output, DVI-D, four USB 3.2 Gen 1 ports, a single gigabit Ethernet from a Realtek RTL8111H controller, and the audio jacks.
