ASRock B550M-ITX/ac

It looks like ASRock will have a second mini-ITX motherboard, this time on the cheaper end of the scale. The B550M-ITX/ac, at first glance however, seems to have some rough layout choices. First of all, the CPU 8-pin connector, is on the rear panel. Whoever thought that was a good idea needs removing from the design team.

The CPU power delivery seems to be an 8-phase design, with a small heatsink to assist. The socket area has two 4-pin fan headers above it to assist, and there is a third on the bottom right of the board, although this is a bit far away for any air coolers. The two DRAM slots in between are single sided latch designs.

On the right hand side of the board is the 24-pin ATX power connector, and four SATA ports in a configuration which makes taking two of the locking cables out impossible if memory is installed – again, an odd design choice. Below this are a USB 3.0 header, a USB 2.0 header, the front panel header, and that third 4-pin fan header.

The chipset and PCIe 4.0 x4 M.2 slot have one combined heatsink, just above the PCIe 4.0 x16 slot. The PCIe slot doesn’t have additional support embedded in it. To the left is the audio codec, in this case it’s the low-end ALC887 design.

The rear panel has a DisplayPort, a HDMI port, two USB 3.2 Gen 1 ports, two USB 2.0 ports, a combination PS/2 port, gigabit Ethernet from a Realtek RTL8111H controller, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, audio jacks, and Wi-Fi antenna for the built in Wi-Fi 5 module (likely Intel’s 1x1 AC3168 solution).

    Right now, it seems more like B for Backordered. They may be priced a bit high, but the demand still seems to be there. Reply

    This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots. It seems that motherboard makers are totally f up(sorry for the expression) the more reasonably priced models in that area. Reply

    Does anyone know if the boards that have the Intel i225-V are shipping with the fixed hardware (v2)? Reply

    Wow, another broken Intel NIC? I wish motherboards would stop using Intel NICs. Reply

    After Googling it looks like v2 is not fixed either... a v3 is coming out. Time to buy Realtek. Reply

    Which is hilarious - I remember when Realtek was the worst when it came to NICs, and Intel/3Com was the standard. :) Reply

    Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.

    Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks! Reply

    I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit. Reply
