Once upon a time, the term 'bigger is better' was a marketing slogan that many companies adopted for its products, but sometimes 'bigger' isn't necessarily practical. For use cases where size (smaller) actually matters, ASRock has unveiled a dinky little motherboard designed for use with its Ryzen based APUs, the X300TM-ITX. Based on AMD's AM4 chipset and the Thin Mini-ITX form factor, it includes one M.2 slot, dual HDMI video output, and support for 64 GB of DDR4-3200 SO-DIMM memory. Thin Mini-ITX in this case means a reduced overall z-height, and the rear panel IO is limited on how tall it can be.

The ASRock X300TM-ITX includes support for most of AMD's Ryzen APUs (all except the new Ryzen 5000 series APUs are listed). This includes Ryzen 2000, Ryzen 3000, Ryzen 4000, and the associated PRO APU parts. On the slender yet unassuming black PCB is a pair of memory slots capable of supporting up to 64 GB of DDR4-3200 SO-DIMM memory. For storage, ASRock includes a single PCIe 3.0 x4 M.2 slot with support for the faster NVMe based SSDs and a single SATA port for conventional storage and optical devices. The X300TM-ITX is designed to harness the integrated Radeon graphics within the APUs it supports as it does away with any full-length PCIe slots.

Due to its smaller than usual Thin-ITX frame, the ASRock X300TM-ITX has less space for larger connectors such as 24-pin 12 V ATX which typically power motherboards. Providing power to the board is a 19 V DC power input on the rear panel and a 4-pin 19 V connector on the PCB itself. Interestingly, ASRock includes an LVDS header, a COM port, and dual HDMI 2.1 video outputs. Regarding USB connectivity, there's USB 3.2 G1 Type-A and a single USB 3.2 G1 Type-C port, with two USB 2.0 front panel headers providing support for four additional ports. The X300TM-ITX uses a single Realtek RTL8111GR Gigabit Ethernet controller. It includes a single M.2 Key-E slot for users looking to add Wi-Fi modules, while audio is handled by a Realtek ALC233 HD audio codec providing a 3.5 mm headphone and 3.5 mm microphone jack pairing.

We expect the ASRock X300TM-ITX to be available to purchase soon, but there's no available pricing at the time of writing.

    I own one of the boards and I have a question about the 19V ATX power delivery. BTW they do make thin ITX boards with a PCIe video slot, I believe one is made by Gigabyte.
    There are many boards now coming out with the 4 pin ATX input power delivery over the 2 pins the boards were using prior to this design change. The only 19 volt Power supply readily available with a 19 volt DC output is made by HDPlex. They come in 200-watt and 400-watt versions with different amperage The adapters for these a 6 pin to 2 pins double-wired for boards such as the Asus Prime H410t/CSM which has a 2 pin input. I know you can run these 4 pin boards with 2 pins only in the 4 pin board Molex but they would be restricted. Asus make another board the Asus H410T2 which has a 4 pin input. If using a brick PS there is only one wire input, albeit a larger diameter, why is it unsafe to double wire the 4 pins and is a 65-watt TDP processor vs 35 Watt TDP, draw more amperage not overclocked and why would 2 boards with the H410 chipset from the same mfg have different power delivery inputs 4 vs 2 pins? I know if the board runs unstable the 2 extra wires would be needed, but on single rail P.S. at these low wattages is it really a problem, ie unsafe due to heat possibly melting delivery wiring if double wired.? Since there are 6 wires on output from the Power Supplies noted above, only 4 wires could be used and 2 pins not connected.

    I'm running this exact board with an hdplex and
    4650g with a 6 to 4 pin input adapter. It's running very smoothly, even with 64gb on full load I'm struggling to get anywhere near 54w. That said, the lack of features is annoying. The uefi is full of options but the lack of sata inputs and single m. 2 is very restrictive. Having to use an lg115x cooler is annoying too

    How nice would it be, if they used their asrockrack team to design such a thing.
    Simple bulletproof B550 chipset, top Notch but not overbuild components, Intel NIC. PCI4. Like a Dell to be customised. I am always amazed how well designed even the cheapest small Dells are.

    You know what's seven more bulletproof than a B550 chipset? No chipset at all, like this here "X300"!

    Ummm, it's the X300 chipset, says so pretty openly right in the name... The "enthusiast" version of the A300 chipset, designed for up to 65-watt processors and EXTREMELY small install footprint.
