This article covers MSI MAG Mortar Intel B460 LGA 1200 Micro ATX DDR4-SDRAM マザーボード.

Overview

The MSI MAG Mortar B460 is a Micro ATX motherboard built for Intel's 10th-generation Core processors, featuring the LGA 1200 socket. It supports everything from the Core i9-10900K down to Celeron CPUs, making it a flexible foundation for budget to mid-range builds. The Intel B460 chipset provides dual-channel DDR4 memory support up to 128GB at 2933MHz, striking a balance between cost and capability. One of the standout features is the extended heatsink design paired with dual M.2 slots, each equipped with MSI's M.2 Shield Frozr thermal solution. This allows NVMe SSDs to run at full speed (up to 32GB/s) without thermal throttling. The board also includes 2.5G LAN and integrated Wi-Fi 6 (802.11ax), delivering modern wired and wireless connectivity out of the box. Positioned firmly in the entry-to-mid-range segment, the MAG Mortar B460 prioritizes stability and value over overclocking headroom. It's an excellent choice for builders who want a reliable, feature-rich platform without paying a premium for unlocked multipliers or PCIe 4.0 support.

Compatibility Guide

CPU socket: LGA 1200, compatible with Intel 10th-gen Core, Pentium Gold, and Celeron processors. Note that 11th-gen Rocket Lake CPUs are not supported. Memory: Dual-channel DDR4, up to 128GB capacity, max speed 2933MHz. XMP profiles are supported but limited to the chipset's ceiling. Form factor: Micro ATX (244mm x 244mm). Fits in most Micro ATX and many standard ATX cases. Expansion slots: 1x PCIe 3.0 x16 (for GPU), 2x PCIe 3.0 x1. Single GPU setups are the intended use case. Storage: 4x SATA 6Gbps ports, 2x M.2 slots (PCIe 3.0 x4 / SATA). Both M.2 slots include Shield Frozr heatsinks. Power: 24-pin main connector, 8-pin CPU power. Recommended PSU wattage depends on CPU/GPU combo — typically 500W to 650W for mid-range builds.

Product Info

The MSI MAG Mortar B460 launched in mid-2020 and remains available through major retailers like . Its price has stayed around ¥10,000–¥12,000, offering strong value for a board with Wi-Fi 6 and dual M.2 heatsinks. The standard warranty is three years from MSI. Market positioning is clearly entry-to-mid-tier. The B460 chipset lacks overclocking support, but the board compensates with premium features like 2.5G LAN, integrated Wi-Fi 6, and robust thermal solutions — features often reserved for more expensive models.

Best Use Cases

Budget gaming PC builders: Pair this board with a Core i5-10400 or i7-10700 and a mid-range GPU like the RTX 3060 for a capable 1080p gaming rig. The B460's stability ensures consistent performance without the complexity of overclocking. Quiet / low-power system builders: The B460 chipset runs cool and often uses passive cooling, making it ideal for silent office PCs, HTPCs, or home servers. The included Wi-Fi 6 eliminates the need for a separate network card. * Compact PC enthusiasts: Micro ATX format allows for smaller cases while retaining decent expansion. Builders who want a full-tower ATX board with more PCIe slots should look at larger options.

Things to Consider

The B460 chipset does not support 11th-gen Intel CPUs (Rocket Lake). You'll need to source a 10th-gen processor, which may be harder to find new. Memory overclocking is restricted — even with high-speed DDR4-3600 kits, the board will cap at 2933MHz. This limits peak memory bandwidth for memory-sensitive workloads. PCIe 4.0 is not supported. Modern GPUs and SSDs will run at PCIe 3.0 speeds, which is still fine for most games but may bottleneck future high-end hardware. The dual M.2 slots share bandwidth via the chipset; using both simultaneously may slightly impact performance on the second slot. ## FAQ
Q: Can I use a Core i9-10900K with this motherboard? A: Yes, it works at stock speeds. Overclocking is not available on B460, so the CPU will run at its rated turbo frequencies. Ensure adequate case airflow for sustained loads. Q: Does this board support Windows 11? A: Yes, it includes TPM 2.0 support. You'll need to enable it in the BIOS under the Security menu. Q: What CPU cooler should I use with this board in a Micro ATX case? A: Any LGA 1200-compatible cooler works. For compact cases, check clearance: air coolers under 155mm height or 240mm AIO liquid coolers are common choices.
