The Mini-ITX form factor has garnered a loyal community, and I proudly consider myself a member of this group. The concept of constructing a gaming system that can be accommodated within a case comparable to the dimensions of a shoebox is incredibly enticing. However, the substantial size of contemporary high-performance graphics cards undoubtedly presents additional challenges.
Although all major manufacturers produce ITX boards, ITX AM5 motherboards remain relatively rare. The X670/E model, in particular, poses significant challenges when attempting to reduce its size to the ITX format due to its dual chip architecture. The available PCB space is insufficient to accommodate all components without addressing considerable obstacles. To the best of my knowledge, Asus is currently the sole manufacturer that has developed an X670E ITX board.
B650/E ITX motherboards are relatively rare. ASRock has consistently championed the Mini-ITX form factor, and the ASRock B650E PG ITX WiFi exemplifies this commitment. This compact board successfully integrates all essential features of the AM5 platform, making it suitable for inclusion in the most compact cases.
Contemporary motherboards are equipped with a significant amount of integrated features and widespread USB connectivity. Consequently, the demand for multiple expansion slots, which was prevalent in the past, has diminished. In reality, it would be unexpected if the majority of gamers utilized more than the primary graphics card slot.
The ITX form factor inherently involves certain compromises; therefore, if your requirements include multiple M.2 slots or additional PCIe slots for components such as sound cards, it is advisable to opt for mATX or ATX motherboards. However, the ASRock B650E PG ITX WiFi is primarily designed for compact systems. The question remains whether it sacrifices too many features to meet its miniaturization objectives.
The ASRock B650E PG ITX, as indicated by its designation, features the B650E chipset, which includes a PCIe 5.0 x16 slot and a PCIe 5.0 x4 M.2 slot. This configuration ensures that the motherboard is as future-proof as currently feasible. Provided that AMD adheres to its commitment to support the AM5 platform for the coming years, there is substantial confidence that one could utilize a Zen 5 or Zen 6 CPU, along with a next-generation PCIe 5.0 graphics card, with merely a straightforward BIOS update. However, it is essential to perform a BIOS update prior to any upgrades, as the motherboard does not support CPU-less BIOS flashback functionality.
In addition to the main M.2 slot, the motherboard features an additional PCIe 4.0 compatible slot located on the rear side. It is crucial to recognize that motherboards typically do not experience significant airflow at the back, making it advisable to utilize this slot for a slower or cooler-running drive intended for bulk storage. Otherwise, it may become excessively warm in that area.
There is no need for concern regarding the primary slot overheating. It is equipped with a substantial heatsink that incorporates a small fan. To address the obvious concern, the fan is indeed quite noisy; however, this can be mitigated by accessing the BIOS and enabling the ‘silent mode,’ which renders it completely silent. Fortunately, one can be assured that a next-generation PCIe 5.0 SSD will possess sufficient cooling capabilities.
The remaining components of the board consist of standard ITX offerings; however, the presence of only two SATA ports may pose a challenge for certain users. Additionally, having just three fan headers represents the bare minimum. Notably, the board supports a front USB 3.2 Gen 2×2 port and features dual ARGB headers, which is commendable. Perhaps the most intriguing aspect is the inclusion of an embedded DisplayPort connector located at the rear of the board.
An eDP connector serves the purpose of connecting to devices such as ASRock’s proprietary 13.3-inch side panel kit. This connector is also featured on the ASRock Z790 Livemixer motherboard. As previously mentioned, it is a rather specialized addition, particularly given that the rear I/O does not incorporate a standard DisplayPort. Its utility is further diminished in a small form factor build, which is unlikely to accommodate a monitor of that size.
The VRM is often a section where ITX motherboards must make concessions. However, the B650E PG ITX features a remarkable 10+2+1 phase VRM with 105a stages. This configuration is more than sufficient to support my Ryzen 9 7950X CPU, even under maximum load. Nevertheless, this level of performance does place a strain on the cooling system of the compact board, which inherently lacks the surface area of the VRM heatsinks found on larger motherboards.
Maintaining adequate airflow within the case is essential for optimal performance; however, I did observe temperatures exceeding 70°C, even with an open case and airflow provided by the AIO cooler. While this temperature is still within acceptable limits, it is crucial to monitor the VRM temperatures if you intend to operate a high core count CPU in a confined space.
The rear I/O configuration is less congested compared to what is typically found on ATX motherboards. The number of USB ports is satisfactory, featuring four USB 3.2 Gen 2 ports (including one Type-C) alongside four USB 2.0 ports. ASRock designates two of the 3.2 ports as ‘Lightning Gaming ports’, which utilize a specialized controller aimed at reducing jitter and latency. I will accept ASRock’s claims regarding this feature. Additionally, there is one HDMI port available, while DisplayPort has been excluded in favor of the previously mentioned eDP.
ASRock has selected the Killer E3100 2.5G LAN and Killer AX1675 WiFi 6E controllers, which feature Doubleshot Pro support. Although Killer network interface cards faced criticism for several reasons in the past, the acquisition of Rivet Networks by Intel in 2020 appears to have significantly reduced the number of complaints.
The optical S/PDIF connector links the line-out and microphone ports. Additionally, the board features a Realtek ALC1220 codec, which is compatible with Nahimic software.
Examination of the ASRock B650E PG-ITX WIFI.
The ASRock motherboard exhibited a slight lag compared to the other B650 boards I have evaluated thus far. However, this should not raise any alarms, as it is common for motherboards utilizing the same AGESA BIOS code to operate within a similar margin of error. Variations of a second or a frame are unlikely to be perceptible.
The ASRock BIOS is organized effectively, featuring clearly labeled settings that are straightforward to locate. While it may lack some of the advanced options found in pricier or overclocking-oriented motherboards, it is not designed for extensive overclocking beyond the basic activation of Precision Boost Overdrive (PBO).
This particular motherboard is specifically designed to accommodate advanced PBO modes and the Curve Optimizer. While a non-X CPU would be an excellent option for pairing with the PG ITX, utilizing an X model can also be advantageous. By setting Tjmax limits to either 75°C or 85°C, one can achieve nearly the same performance as a standard chip, all while ensuring efficient cooling and reducing stress on the motherboard’s VRM.
The discussion pertains to SFF systems. Personally, I find the concept of a modified 7000 series processor that consumes minimal power while being paired with a straightforward and silent air cooler to be quite appealing. Many of you likely share this sentiment, despite it seeming somewhat counterintuitive in the context of high-performance CPUs and gaming setups. In certain instances, a more minimalist approach can indeed yield superior results.
The conclusion regarding the ASRock B650E PG-ITX WIFI.
Mini-ITX motherboards are largely considered niche products. For the majority of gamers, a standard ATX motherboard is typically sufficient, often at a lower cost and with superior voltage regulation modules (VRMs) or additional USB and SATA ports. However, enthusiasts of small form factor systems are distinctly seeking SFF motherboards and are willing to forgo features such as multiple M.2 slots or PCIe slots for expansion cards.
The ASRock B650E PG ITX cannot be directly compared to an ATX motherboard based on conventional standards. However, it provides significant advantages such as upcoming PCIe 5.0 support and the potential for future upgrades through the AM5 socket. By incorporating either 32GB or 64GB of DDR5-6000 memory, along with your preferred graphics card and any CPU from the 7950X series downwards, you can create a high-performance gaming system that fits comfortably within a compact desk setup.
You may also consider placing it in a compact case equipped with a 7600 CPU, applying undervolting techniques to achieve a remarkably quiet system. ITX configurations offer significant flexibility.
The B650E ITX motherboard provided a comprehensive and refined experience. I appreciate the straightforward nature of ASRock’s BIOS; however, the fan settings on the PG ITX were rather intense. This is certainly something you will observe upon initial startup, as the fan can be quite noisy. Nevertheless, a single adjustment in the BIOS will render it virtually unnoticeable.
The VRM demonstrates impressive capabilities, designed to meet the demanding specifications of Ryzen 7000 CPUs, and is anticipated to support future Ryzen 8000 and 9000 CPUs as well. However, it is important to monitor the VRM temperatures, as they may become excessive in environments with inadequate airflow.
You are likely aware of whether a Socket AM5 Mini-ITX board suits your needs. While there are notably competitive alternatives available at this price point, they lack the comprehensive PCIe 5.0 support offered by the ASRock model. The Asus B650E competitor is priced at a minimum of. Consequently, the ASRock B650E PG ITX stands out as having no direct rivals in its category. Its forward-thinking feature set, robust VRM, and excellent value for money position it as one of the few AM5 boards worth considering for small form factor enthusiasts who are looking towards the future.
