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.

    ASRock B450M Pro4 is not a 6+3 power system but a 3+3. You have to remove the heat sink to see the MOSFET Hi and Lo combos and IC controlers

    "Strix B450-F Gaming ..... Also present is a duo of M.2 slots with both having support for PCIe 3.0 x4 M.2 drives, while the top slot which supports both PCIe and SATA drives up to a size of M.2 2280 (22 x 80 mm), the bottom slot only supports PCIe 3.0 x4 drives with a sizing up to M.2 22110 (22 x 110 mm)."

    ALARMINGLY WRONG!

    edit - to remove any doubt - in full, the specs are:

    ** When the M.2_1 Socket 3 is operating in SATA or PCIE mode, SATA6G_5/6 ports will be disabled.
    *** When the M.2_2 is occupied by M.2 device, PCIe x16_1 will run at x8 mode."

    I run windows from external SSD so I need fast USB ports for it to run smooth. Can I replace the USB ports by 3.2 gen2 when needed?
  • g0rnex - Sunday, June 23, 2019 - link

    I run win10 from an external SSD. for that I need a fast USB connection for windows to run smooth.

    Would it be possible to change the USB ports in the future? OR even now already by a 3.2 gen2. Or wouldn't replacing the ports speed up my connection with the external SSD?

    Also I would like a good bluetooth connection. Do I need to use an adapter?

    looking into making this build:
