- Blazing memory capabilities: Four DDR5 memory slots supporting up to 256GB and high-frequency overclocking profiles (DDR5 8000 – 5600 OC / 5600 – 4800 JEDEC) let you push responsiveness and bandwidth for memory-intensive tasks.
- Modern connectivity everywhere: Built-in Wi-Fi 6E with EZ Antenna and Realtek® 8125D 2.5G LAN deliver low-latency, high-bandwidth networking for large transfers, online collaboration, and stable gaming sessions.
- Extensive storage and expansion options: Dual M.2 slots (PCIe 4.0 ready) and four SATA 6G ports, combined with flexible RAID support, give you the capacity and performance options to build a fast, redundant, or hybrid storage configuration.
- Compact, stylish, and practical: The Micro ATX form factor offers a space-efficient platform without compromising on essential I/O, expansion, or professional-grade features—ideal for small-form-factor builds that demand capability as well as looks.
- Feature — Advanced memory platform: Four DDR5 DIMM slots supporting up to 256GB and a wide range of frequencies (DDR5 8000–5600 OC / 5600–4800 JEDEC). Whether you’re running heavy databases, virtual machines, or creative suites, the memory subsystem is designed for high throughput and stability.
- Feature — Next-gen networking and wireless: Integrated Wi‑Fi 6E with MSI’s EZ Antenna brings access to the 6 GHz band for reduced congestion and higher throughput, while the Realtek® 8125D 2.5G LAN port ensures robust wired performance for downloads, streaming, and online play.
- Feature — Flexible storage and RAID-ready: Two M.2 slots with PCIe 4.0 support plus four SATA 6G connectors enable high-speed NVMe storage and ample mass storage. RAID options include RAID 0, RAID 1, and RAID 10 for SATA, plus RAID 0 and RAID 1 for M.2 NVMe—letting you balance speed, redundancy, or both.
- Feature — Essential expansion and integrated graphics support: A full-length PCIe x16 slot (PCIe 4.0 capable) and a PCIe x1 slot provide room for discrete GPUs, PCIe add-in cards, or specialized expansion. Integrated graphics support adds flexibility for builds that don’t require a dedicated GPU or for troubleshooting and multi-display setups.
- Feature — Contemporary I/O and onboard media: USB 3.2 Gen 2 Type-C and Type-A ports put fast peripheral connectivity at your fingertips, while Realtek® ALC897 audio delivers clear onboard sound for conferencing, content creation, and casual entertainment.
