Before You Buy an AM4 ITX Motherboard

Probably the most important thing that you need to know about AM4 ITX boards before buying is their limited expansion due to their size. Although ITX board are packed with features and are enough for the vast majority of users, some may encounter issues when planning to upgrade. For example, although your memory will run in dual channel, there will be only two slots on the board. So, if you plan to go to 32GB from 16GB, you’ll need to buy 2×16 kit and re-sell the old one instead just adding just 16GB to your existing 16GB is you had four memory slots.

One other down side is that your board will only have one PCI-e slot that will be populated with your graphics card. That leaves you with no expandable options for add-in cards like capture cards, etc. But luckily, most of those come in an USB variety nowdays.

What to Consider When Buying AM4 ITX Motherboards

One key thing you need to consider before buying is what is your use case for your SFF PC. That way you’ll be able to choose the best parts to suit your use scenario. For example, if you need more storage space, look for more SATA/m.2 slots. The same goes for USB’s. If you need plenty USB ports, you may want to go with an X570 board for their wider connectivity options.

Chipset

AM4 ITX motherboards come with a couple of different chipsets which offer a different set of features. If you are building a fresh system, we suggest going with X570, B550 or B450 if you don’t mind not having PCI-e Gen 4.

Compared to B550, X570 chipset offers better IO and usually better VRM’s for overclocking. However, we recommend most users go with a B550 board for its lower price which doesn’t sacrifice much on features.

B450 is an older chipset that AMD promised would get a BIOS update to support Ryzen 5000 series. If you decide to go with a B450 board, please check the manufacturer’s site first for Ryzen 5000 support. The main thing you will be missing with these boards is Gen 4 PCIe.

RAM Slots

Most of these boards if not all of them will come with just two RAM slots due to size limitations. The only thing you need to consider regarding your RAM slots is whether your motherboard supports the memory you plan to buy and will it work on its max frequencies.

Expansion Slots

As we mentioned earlier, Mini ITX motherboards come with a single 16X PCI-e slot. There may be a few mini DTX boards with an additional 1x PCI-e slot above the main 16X but those are extremely rare and won’t be supported with the vast majority of ITX PC cases.

The slots that you can get more than one is M.2. These slots are in the vast majority of modern boards just a shrunk down PCIe 4X, made for SSD’s. There are adapters that can extend these into full PCIe slots for add-in cards but we won’t go in depth about those.

SATA Ports

When buying an AM4 ITX motherboard you can expect to get in most cases 4 SATA ports. Some boards may come with more and some can come with less. We discovered that most of the boards come with 4 SATA 3 slots on average which is plenty for a SFF system.

Display Ports

The display ports on the IO side of the motherboard are meant for APU’s.

APU is a term that AMD uses for their processors that feature integrated graphics. These display ports (usually HDMI and Display Port) should only be used if your mini-ITX system doesn’t have a dedicated GPU.

Additional Features

Some useful features that are great but not a must are:

  • Front panel USB-C connector
  • CMOS reset switch
  • BIOS update without a CPU (this one can save you a big headache if pairing an older board with a new CPU)
  • Dual M.2 slots
  • WIFI & Bluetooth
  • More than 2 fan headers

Tips for Buying and Using AM4 ITX Motherboards

Before you buy a motherboard it’s important to take into consideration what are the rest of your components. For example, if you are planning to use only M.2 storage to reduce cable clutter, make sure that your motherboard has two M.2 slots. Also, if you are planning to run a 24/7 overclock ideally, you’d want to go with a motherboard with a stronger VRM solution.

  • Make sure that the motherboard has enough I/O for your use case
  • Fan connectors could be an easy oversight. Make sure the motherboard has enough of them or you can always add a fan controller if your case has enough space
  • Check the VRM’s if you are planning to run a 24/7 overclock

Just like the bigger ATX B450 model, the MSI B450I PLUS AC motherboard is also a part of the company’s Gaming Range and therefore shares the similar features and the similar available connections. Besides the form factor, the primary difference between these two boards is the inclusion of the Dual-Band Wi-Fi module provided by Intel. Is it worth your money?

The limitations of Mini-ITX motherboards are shown here through the presence of a single PCI-Express 3.0 x16 slot (full-length), along with the storage options provided by four SATA ports. All of these ports come with straight-angled connectors, which can be found below the model’s 24-pin power input. There’s also a single M.2 slot (supports SATA drives up to M.2 2280 or PCI-Express 3.0 x4), while the 8-pin ATX 12V input provides power to the processor.

When it comes to aesthetics, this Mini-ITX motherboard sports a black PCB with heatsinks that wear the MSI Gaming’s well-known black and red color scheme. Regarding memory support, the B450I GAMING PLUS AC features two slots that can house 32GB of DDR4-3466. Both the ECC DDR4 and non-ECC memory is supported, although it’s worth noting that ECC memory will operate in non-ECC mode.

Taking a look at the unit’s rear panel reveals the total of six USB type-A ports. There are two USB 2.0 ports and four USB 3.1 (5GBps) ports – unfortunately, the B450I GAMING PLUS AC lacks any kind of type-C connectivity. As we have mentioned in the intro, there’s an Intel 3168 802.11ac Wi-Fi adapter that allows installation of the included antennas, as well as the LAN port, HDMI and DisplayPort, and three 3.5mm audio jacks.

If you’re searching for a quality mini-ITX board that will house your brand new Ryzen CPU, this model is a pretty solid choice. The fact that it’s wallet-friendly turns it into an excellent option for the PC enthusiasts with lower budgets.
