Our newest mini-ITX motherboard, from Asus and that includes the B850 chipset, is considerably inexpensive than its X870 counterparts, however that doesn’t imply it’s low cost. The ROG Strix B850-I Gaming Wifi is priced round $349.99, direct from Asus, and across the similar worth at Newegg, making it the highest-priced B850-based Mini-ITX SKU. For the cash, you get comparable {hardware} to the competitors, together with Asus’s broad AI help and powerful software program ecosystem.
Hardware-wise, you get two PCIe 5.0-capable M.2 sockets, a strong audio resolution, quick networking together with Wi-Fi 7, succesful energy supply, and DIY-friendly design – for probably the most half, not a lot totally different than its friends, save for the 2 quick M.2 slots. The two-DIMM board helps 128GB of RAM, with pace variations largely irrelevant except you’re making an attempt to interrupt overclocking information. Asus’ options, together with AI Advisor, Overclock, Networking II, and AEMP options, assist simplify setup and maximize efficiency. Additionally, it presents DIY-friendly design, together with up to date PCIe Slot Release performance and M.2 slide characteristic.
Below, we’ll examine the board’s details and determine whether it deserves a spot on our Best Motherboards list. But before we share test results and discuss details, we’ll list the specifications from Asus’ website.

Design of the B850-I Gaming
Image 1 of 3
Mini-ITX motherboards don’t leave a lot of room for the design team to get creative, but Asus has done a good job on heatsink shape and a placard sporting the Asus ROG branding (that ROG symbol is also perforated to let cool air in to the fan below). The bottom heatsinks (there are two there, you’ll see later) are responsible for the first PCIe M.2 socket and the other for the single PROM 21 chip. Strix is written prominently across the top. All of this sits on a 10-layer, matte-black PCB.
Focusing on the left side, we get a better look at the blue and purple accent design feature / stealthy fan intake on the large heatsink. Hidden below is a small fan to keep the power delivery temperatures in check. It does so, and quietly in our testing using the default settings. Powering the board is a single 8-pin Procool EPS power connector.
Across the top are all four of the board’s 4-pin fan headers. The headers, from left to right, the CPU, AIO, CHA, and Extra Flow (for DRAM or other components, Asus says), all support PWM- and DC-controlled fans/pumps. Output is limited to 1A/12W maximum each, but that’s still enough to power a few fans or an AIO solution in a small Mini-ITX chassis. Next to that are two 3-pin ARGB headers.
Looping back around, hiding under the left heatsink, is the power delivery consisting of 13 total phases. The DIGI+ ASP2205 PWM controller manages power, sending it to the 10 Infineon PMC41420 90A MOSFETs dedicated to vCore. Robust for the form-factor, it’s capable of handling flagship-class processors, even with some overclocking. They ran a bit warm (60 degrees Celsius according to the internal sensor) compared to the larger boards, but were still well within specification and close to the competing ASRock B850I Mini-ITX board.
Just before the edge of the board are the two reinforced DRAM slots with the locking mechanism located at the top. Asus lists support up to DDR5-8400, which is plenty fast for the platform. Asus’ DIMM FIT/DIMM FIT Pro and AEMP features help get the most out of your RAM, even if it doesn’t have an XMP profile. No matter what you put into this machine, Asus can help you get the most out of it.
On the far edge, at the top, is the Q-LED feature that lights up during the POST process. Below that is the 24-pin ATX connector to power the board, followed by a front panel USB 2.0 header. Below that are two vertically oriented SATA ports, the front panel USB 3.2 Gen 2 (10 Gbps) header, and a 19-pin USB 3.2 Gen 1 5 Gbps) header. Wrapping up all the pointy parts is a 2-pin temperature sensor header, a CPU Overvolt header, and the front panel header.
Along the bottom edge, we find the single PCIe 5.0 x16 PCIe slot that uses the PCIe Slot-Release to secure and easily remove your graphics card. North of that, working from PCB level up, you have the B850 chip with its own heatsink. In the same vertical space is the first PCIe 5.0 x4 socket, which also has an independent heatsink. The second PCIe 5.0 x4 socket sits on the back and does not have a heatsink. Both sockets support up to 80mm modules and support RAID0/1/10 modes (for 9000 series processors – otherwise it’s RAID 0/1 modes only).
Audio is handled by the modern, mid-range Realtek ALC4080 codec and supplemented by a Savitech SV3H712 amplifier. Connections include line in/out, microphone in, and an SPDIF optical output, along with the front panel header. Most should be satisfied with this configuration.
The rear IO on this board is surprisingly sparse, particularly in terms of USB ports. On the left, you get two USB 2.0 ports, while below that is the Clear CMOS button and an HDMI output for using integrated graphics. To the right is a vent for the VRM, followed by another stack of USB ports, this time featuring four total 10 Gbps Type-A (red) ports and two Type-C ports (10 and 20 Gbps, respectively). Above that is the Intel 2.5 GbE port and the Q-Antenna connectors for Wi-Fi 7. Below the audio stack is the BIOS Flashback button and the multi-function Flexkey. This is typical fare for a Mini-ITX board, but eight USB ports (six Type-A) could be limiting.
