This article covers MSI B650M Project Zero ゲーミングマザーボード (AMD Ryzen 9000.
The MSI B650M Project Zero is a Micro-ATX motherboard that relocates virtually all connectors—power, fan headers, front panel headers—to the back of the PCB. This “Project Zero” design philosophy lets builders achieve an exceptionally clean, near-cable-free interior when paired with a compatible case. It supports AMD Ryzen 7000, 8000, and 9000 series processors on the AM5 socket with DDR5 memory. Targeting the mid-high end of the market, this board comes with PCIe 4.0 M.2 slots, 2.5Gbps LAN, Wi-Fi 6E, and Bluetooth 5.3. It is an ideal foundation for a visually stunning gaming rig or a tidy workstation build. The key trade-off is case compatibility: you need a case specifically designed to work with rear-connector motherboards.
The B650M Project Zero uses the AMD AM5 socket, compatible with all Ryzen 7000/8000/9000 series processors. Memory is limited to DDR5, with official support up to DDR5-7600+ (OC). The form factor is Micro-ATX; it can physically fit in most ATX or MATX cases, but the rear-connector layout requires a chassis with a cutout on the back (MSI’s Project Zero series or select third-party models) to route cables cleanly. Expansion includes one PCIe 4.0 x16 slot, two PCIe 4.0 M.2 slots, and several SATA 6Gb/s ports. Power connectors are a standard 24-pin ATX and an 8-pin CPU power connector. The rear I/O features USB 3.2 Gen 2x2 Type-C (20Gbps), HDMI, and DisplayPort outputs.
Check the retailer's page for the latest price. It is built on the AMD B650 chipset and emphasizes memory overclocking stability. The warranty is the standard three years from MSI. Availability is wide through , major PC retailers, and the MSI online store. This board sits in the upper-mid range. Its standout feature is the Project Zero hidden-connector layout, which appeals to builders who prioritize clean aesthetics.
Aesthetic-focused PC builders: If you want a showcase build with minimal visible cables, this board is perfect when paired with a compatible case. The result is a near-cable-free front side. Mid-high-end gaming PCs: Combine with a Ryzen 7 or 9, DDR5-6000+ memory, and a PCIe 4.0 GPU (e. g. , RTX 4070 or RX 7800 XT) for a powerful, clean-looking system. * Enthusiasts who enjoy tinkering: The unique layout makes cable management a breeze and creates a sense of accomplishment. However, beginners should ensure they buy the right case.
Case compatibility is the biggest caveat. You must use a case that supports rear-connector motherboards (MSI Project Zero cases or a few third-party options). Installing this board in a standard case largely defeats its purpose and may cause interference. Also, the B650 chipset offers fewer PCIe lanes than the X670/X870 series. Multi-GPU setups or heavy expansion with multiple NVMe drives might saturate the available bandwidth. For most single-GPU gaming or content creation builds, this is not an issue. Memory overclocking stability depends on the CPU’s integrated memory controller. Reaching DDR5-7600+ requires careful component selection and possibly manual tuning.
Q: Can I use this motherboard with a regular ATX case? A: Physically yes, but you will lose the clean-cable benefit because standard cases lack the rear cutouts for the reversed connectors. Cables would need to bend awkwardly, and some headers may not reach the back. A dedicated Project Zero case is strongly recommended. Q: Does it support Ryzen 9000 series out of the box? A: MSI lists support for Ryzen 9000 series. An initial BIOS update may be required, but the board has BIOS Flashback, allowing updates without a CPU installed. Q: Why no PCIe 5.0? A: The B650 chipset is PCIe 4.0 native. The slots and M.2 connectors are PCIe 4.0 only. For PCIe 5.0, consider X670E, X870, or future chipset boards.
