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).

    Looks like some nice mATX versions this round, nice! Reply

    I was hoping to see a $75-$90 board. Reply

    Fortunately, this component is a unique motherboard among B550 and well worth reading up on [add link].
    Needs to be edited.

    There's a noise sensor which can adjust fan speed for maximum quietness with good thermals. Saw it on the KitGuruTech video. The noise sensor isn't there to spy on you though. Reply

    The quality of the editing here is shit tier. Seriously, just run the articles through Grammarly before publication. It's free and it spots plenty of errors. Reply

    Sadly none of the mITX boards have more than 6 external USB ports. My old ASUS mITX has 8! And in really small mITX cases you can't add a bracket with more USB, because the two brackets are already used by the gfx card. Guess I have to wait for an enthusiast mITX board )-: Reply

    Or, just maybe, get a usb dongle with 4 ports? Reply

    That is disappointing. The number of USB devices people need to plug in can't be dropping, surely? I know I've got more now then even a year ago. Reply

    Are they really going up? I have 2 USB devices plugged in to my system - a keyboard and a mouse. I occasionally plug a USB stick in one of the front ports to transfer files. My phone and tablet sync over wifi, they don't get plugged in. I have a charger behind my desk and a cable to charge them. My printer is on the network.
    The one place I DO need lots of USB ports is also the place where I have a small cube case machine, with no discreete GPU, because it doesn;t need one. On that one I added a USB PCI card to get enough ports. In addition to the keyboard and mouse, that machine is on my workbench where it connects to several electronic test instruments and I have multiple cabled for programming microcontrollers. I also have a USB microscope for board inspection. And then I have 3 more USB devices connected for my other hobby that shares the bench. Plus a front port kept free for USB sticks.
    So the use case I have for more USB has the PCI slots open to add expansion cards, the use case where I have a discrete GPU eating up the slot space doesn't need an excess of USB ports.

    I use 3 USB 3.0 ports just for my Oculus Rift Reply
