ASRock B450 Gaming ITX/ac

The B450 Gaming K4 uses similar gunmetal grey heatsinks designs as the B450 Gaming K4, which feature fins to help direct airflow through the channels. The board features support for ASRock’s Polychrome RGB technology, however the B450 Gaming-ITX/ac has no onboard LEDs with the RGB capabilities coming through the same pairing of available headers.

The B450 Gaming ITX/ac has a single full-length PCIe 3.0 x16 slot featuring ASRock Steel Slot protection, and has a total of four SATA 6 Gbps ports with all of them featuring straight angled connectors. For M.2, the Gaming ITX/ac model features a single PCIe 3.0 x4/SATA slot located on the rear of the PCB.

As is usually the case with Mini-ITX form factor motherboards, the ASRock B450 Gaming ITX/ac has a total of two RAM slots giving a maximum supported capacity of up to 32 GB of DDR4. One of the advantages to Mini-ITX is the length of the tracks between the RAM slots and the CPU socket meaning better memory capabilities is possible, which in this case is shown through DDR4-3466 support, compared to DDR4-3200 for the Gaming K4. 

On the smaller form factor Fatal1ty B450 Gaming ITX/ac rear panel is two USB 3.1 10 Gbps ports (Type-A and Type-C), two USB 3.1 5 Gbps ports, two USB 2.0 ports, a HDMI output, a DisplayPort 1.2 output, two antenna ports for the integrated Intel 802.11ac Wi-Fi module and a PS/2 combo port. The five 3.5mm audio jacks and S/PDIF optical output are governed by a high-quality Realtek ALC1220 audio codec, while the LAN port is driven by an Intel I211AT Gigabit networking controller.

Overall, the smaller B450 Gaming ITX/ac compared to the K4 has higher quality integrated controllers and omits any form of built-in RGB. The new ASRock Fatal1ty B450 models directly replace the currently available B350 offerings and as it stands currently, with the B450 Gaming ITX/ac is set to cost $129.99.

    Signed up to point that out. Needs to be fixed. It’s the only ITX board supporting 2x which sets it’s apart form the competition Reply

    Glad to see more options in the mATX range with two M.2 slots, not just from AsRock this time around. My next rig will either be based on the AsRock B450M Pro4 or one of the MSI B450M Mortar boards. Will wait for actual VRM setup and overclocking results / general tests to see which one will be it. I had motherboards from both manufacturers and was pleased with both. MSI has the advantage of offering PCIe M.2 options for both slots as well as SATA. One question regarding that: if I install a 3.0 PCIe x2 M.2 SSD into a 2.0 PCIe x4 slot, what will be the speed ramifications? Can it only use 2.0 PCIe x2 or can it use the full x4, thus being similar in speed to a native 3.0 PCIe x2 setup? :) Still waiting on mATX x470 mainboards. Reply

    .3.0 x 2 is the same speed as 2.0 x 4 Reply

    Except that a 3.0 x2 drive is almost certainly x2 because it only has 2 PCIe lanes (cutting down on them is one of the ways the cheaper drives pinch pennies), which means it will be connected at 2.0 x2; at that point you might as well just use a SATA drive and save a bit more money. Reply

    Thanks for providing an answer to my actual question. :) Reply

    You will get a 2 lane PCIe 2.0 connection, that means 1 GB/s. This is 1/4 of a PCIe 3.0 4-lane usual NVME drive, but real life you may get closer to 80% of the performance. Reply

    Finally some budget boards with solid VRMs. Reply
  • skpetic - Tuesday, July 31, 2018 - link

    There are some seriously shady stuff going on with VRMS om X470 og B450. Check out Buildzoid on youtube. Asus B450 STRIX ITX board is single phase for SoC. Several of the Gigabyte B450 and X470 boards in reality have half the advertised amount of phases or are using doublers:

    hahaha... no

    Asus with the absolute trash tier VRM heatsinks
    AsRock with fake phases
    Gigabyte with fake phases and trash VRM heatsinks
    MSI with no Vcore offset
