Power: 24-pin ATX main, 8-pin EPS CPU. Recommended PSU: 650W or higher (depending on CPU/GPU combo). * Networking: WiFi 6 (802.11ax) + Bluetooth 5.2, Realtek 1GbE Ethernet.

Product Info

The ASUS B650EM MAX GAMING WiFi launched in late 2025 as a mid-range motherboard. It positions itself between entry-level and mainstream, offering premium features like PCIe 5.0 M.2, WiFi 6, and triple M.2 slots in a compact mATX form. The price is around ¥31,000, making it cheaper than many ATX B650 boards while still being well-equipped. The standard warranty is three years.

Best Use Cases

Budget 1080p/1440p Gaming Builds: Pair with a Ryzen 5 7600 or Ryzen 7 8700F for a cost-effective gaming rig. The PCIe 5.0 M.2 slot supports the fastest SSDs. Not ideal for hardcore overclockers who prefer premium B650E or X870E boards. Compact Creative Workstation: The mATX size fits small cases, and three M.2 slots provide ample storage for video editing or 3D rendering projects. WiFi 6 reduces cable clutter. But be aware that the board only has one DisplayPort output for iGPU. * Office/Productivity PC: Combine with a Ryzen 5 7500F for a snappy office machine. The lack of onboard USB-C video output may be a minor inconvenience for some monitors. ## Alternatives
Competitors in the same price range include the GIGABYTE B650M GAMING PLUS WIFI and ASRock B650M Pro RS WiFi. The GIGABYTE board has a larger VRM heatsink but only two M.2 slots. The ASRock board offers similar rear USB 10Gbps Type-C but only one PCIe 5.0 M.2 slot. The ASUS B650EM MAX GAMING WiFi stands out with three M.2 slots (including one PCIe 5.0) and BIOS Flashback, making it a better choice for storage-heavy users.

Things to Consider

Case Size: As an mATX board, it will leave a gap at the bottom in ATX cases. Consider cable management covers if aesthetics matter. M.2 Slot Placement: The PCIe 5.0 M.2 slot sits directly above the PCIe 5.0 x16 slot. Thick graphics cards may obstruct the M.2 heatsink; check clearance before assembly. VRM Capability: 8+2+1 phases are sufficient for Ryzen 7 CPUs, but if you plan to run a Ryzen 9 7950X or future high-end chips at full load, a higher-phase board is recommended. iGPU Outputs: Only DisplayPort and HDMI; no USB-C video output. APU users (Ryzen 8000G series) should be aware of this limitation. ## FAQ Q: Can I use a Ryzen 7 7800X3D with this motherboard? A: Yes. The AM5 socket supports it, and the VRM is adequate for gaming workloads. A BIOS update may be needed for the latest X3D chips. Q: How many PCIe 5.0 SSDs can I install? A: Only one. The other two M.2 slots are PCIe 4.0. If you need multiple PCIe 5.0 SSDs, consider a higher-end X670E or X870E motherboard. Q: Does BIOS Flashback work without a CPU installed? A: Yes. You can update the BIOS using only the power supply and a USB flash drive, without a CPU or memory. This is useful for ensuring compatibility with newer Ryzen processors.
