ASRock B450 Gaming ITX / ac and B450 Gaming K4 Motherboard Reviews



With the launch of the new AMD B450 budget-focused chipset, we take a look at two Fatal1ty game-based ASRock motherboards; B450 Gaming ITX / AC and Fatal1ty B450 Gaming K4. Both models seem to provide good value for money to players on a strict budget, but do not need features such as NVIDIA SLI multi-graphics card support.

ASRock B450 Gaming ITX / AC Overview

The ASRock B450 Gaming ITX / AC has a miniITX form factor and is a direct replacement to the previous B350 Gaming ITX / ac motherboard. As expected, this model is marketed on players wishing to build a smaller form factor game system focusing on either a single graphics card or use with one of Ryzen-based APUs, Ryzen 5 2400G and Ryzen 3 2200G. The Gaming brand is signified using a pair of red metallic cooler batteries and a pair of red colored RAM slots.

As we concluded in our ASRock X370 Gaming-ITX / ac mapping, the B350 variant gave better value when compared to the more enthusiastic X-series chipset; This is true for users who do not seem to make use of the X370's extra native USB 3.1 connection and PCIe bandwidth, which is pretty good on an ITX motherboard with space constraints as a factor. This time, compared to the X470 to the B450, the updated ASRock X470 Gaming-ITX has a stronger feature set on paper, with better sound on board as a major enhancement and with a $ 179.99 dollar dwarf dimming the B450 Gaming ITX / AC model as sits on a more modest $ 129.99.

Having said that, the B450 Gaming ITX / AC aims to offer players a reasonable little form factor option without sacrificing too much on quality, while the core gaming features are expected from a Fatal1ty branded motherboard. Including a higher quality Realtek ALC1220 audio codec and Intel I211AT Gigabit network controller means premium while keeping the price at a modest and less expensive level.

B450 Gaming ITX / AC's performance is well in line with other performance and performance performance plates, with strong showings in a variety of benchmarks, including handbrake, POV-Ray and 3DPM. ASRock has consistently good POST times and the B450 Gaming ITX / AC is no different in these greetings. While game performance is a bit beyond expected ground, it is unlikely to make a big difference to the overall gaming experience, with the average margin within the margin. The sound quality of the Realtek ALC1220 audio code is good as expected, and the B450 Gaming ITX / ac shows one of the best DPC latitude views so far.

Control Features

The ASRock B450 Gaming ITX / AC uses good quality control such as the Realtek ALC1220 audio codec and Intel I211AT Gigabit LAN network drive, focusing on performance, but keeping the expected Fatal1ty-based game theme.

Although there are constraints on connection due to the miniITX form factor, the B450 Gaming ITX / ac still retains space for a pair of USB 3.1 10 Gbps ports with both a Type -A and Type-C present. The two RAM slots support up to DDR4-3466 +, which is one of the main advantages of choosing a second generation B450 chipset motherboard over the first generation like the B350 and X370. ASRock B450 Gaming ITX / AC as its B350 predecessor also comes with a three year warranty as standard.

ASRock B450 Gaming ITX / ac Visual Inspection

The majority of the aesthetics on boards like this match a red and black theme. Both covers have a red metal finish, while the chip set has the ASRock Fatal1ty logo printed on. The B450 Gaming ITX / AC does not contain built-in LED lighting, but present is an addressable LED header to use ASRock's Polychrome-certified RGB function.

The Mini-ITX form factor brings certain victims over an ATX card, with the primary cuts coming through memory and PCIe capacity. The B450 Gaming ITX / AC has a total of two memory slots that can support up to DDR4-3466, with a maximum capacity of up to 32 GB (2 x 16 GB) of total system memory. Simple and full-length PCIe 3.0 x16 lane has a full coverage of ASRock's Steel Slot Armor Enhancement to protect against heavier graphics cards. Cooling options supplied by ASRock include a single 4-pin CPU fan head and two 4-pin heads dedicated to fans and water pumps.

ASRock has included a single Realtek ALC1220 audio codec that has been accompanied by a pairing of Nichicon Gold Sound Capacitors. As expected with a good quality codec presentation, Realtek ALC1220 offers a total of six 3.5 mm audio inputs with a single S / PDIF optical output that also exists. The built-in audio supports up to 7.1 surround sound. Located above the audio portion of the PCB is an Intel 3168 802.11ac 2×2 Wi-Fi module that also offers users Bluetooth 4.2 connectivity. The wired network comes via a single LAN port and is controlled by an Intel I211AT Gigabit Ethernet controller.

B450 Power Supply Comparison for Motherboards

While we have not previously reviewed the B350 Gaming ITX / ac motherboard, we got the hands on the X370 variant, X370 Gaming ITX / ac as expected and no surprise as it shares the same power supply as the B450 Gaming ITX / AC model. The power supply is organized in a 6 + 2 configuration with a total of ten Sinopower SM7341EHKP dual N channel MOSFET, with six dedicated to CPU and four especially for SoC. Power management is an Intersil ISL95712 PWM controller operating at 3 + 2. Although each of the CPU phases connects a single driver, ASRock adds two phases per channel on SoC, while the CPU part has a single driver per phase. In total there are eight electrical outlets with one choke per CPU phase and one per two phases on the SoC. While a slim red metallic heat sink covers the CPU segment of the power supply, the SoC area is open and if the use of B450's overclocking features is planned, sufficient passive airflow is required.

B450 Gaming ITX / ac has four SATA 6 Gbps ports with each port with a right angled connector. These are located to the far right of the RAM slots and just below the USB 3.1 5 Gbps header. The SATA 6 Gbps slots support RAID 0, 1 and 10 arrays.

A single M.2 2280 (22 x 80 mm) track is present and supports both PCIe 3.0 x4 and SATA SSDs. This slot is located on the back of PCB due to a size limitation of the miniITX form factor, supporting super-fast NVMe drives, and does not share the full-length PCIe 3.0 x16 bandwidth.

The B450 Gaming ITX / AC Back Panel has been enhanced by the first generation of AM4 motherboards (B350 / X370), including a USB 3.1 10 Gbps (Type-A and Type-C) gate; Type-A comes native to the B450 chipset while Type-C is thanks to the inclusion of an ASMedia ASM1543 chip. Adding the USB connection are two additional USB 3.1 5 Gbps Type-A ports with additional USB 2.0 ports present. The B450 Gaming ITX / AC supports AMD's Vega infused Ryzen APUer, and while the B350 Gaming ITX / AC has two HDMI outputs, the B450 is upgraded, replacing one of the HDMI outputs with a DisplayPort 1.2 output. A total of five 3.5 mm gold-plated audio connectors and S / PDIF optical output make up Realtek ALC1220 code-controlled audio-based audio solution, with both wired and wireless networks, thanks to a LAN port of Intel's I211AT Gigabit Controller and Wi-Fi capability that comes on due to an Intel 3168 802.11ac 2×2 Wi-Fi adapter; The inclusion of an Intel 3168 also offers the ability to connect to Bluetooth 4.2 devices, as well as provide backward compatibility.

In the box

Since there is little space available on a miniITX motherboard, the accessory bundle reflects this. Everything to get a system up is included, such as SATA cables and an M.2 drive installation screw; The two antennas are also included in the bundle to connect to a wireless network. Inside the box, we get the following:

  • Driver Disk
  • Quick Start and Software Guide
  • M.2 Drive Mounting Screw
  • Behind the I / O
  • Two SATA Cables (A Right Angle and Right) [19659079] ASRock Post Cards
  • 2 x Intel 3168 802.11ac Wi-Fi Antennas
