- Supports up to 128GB of DDR4 memory and includes four memory slots.
Cons:
- Supports AMD 3rd Generation Ryzen processors rather than newer AM5 chips.
- Uses DDR4 memory, limiting it to an older memory platform.
- Networking is 1Gb LAN rather than 2.5Gb or faster.
This board makes sense when you already have compatible AM4 components or want a cost-conscious dual-drive setup. It offers useful storage flexibility in a compact Micro ATX format, but it is less suitable for buyers building around Ryzen 7000-series or newer processors.
Compact Choice – Gigabyte A520I AC Mini-ITX
The Gigabyte A520I AC is a compact Mini-ITX motherboard for shoppers who want computer motherboards with multiple M2 slots but are building in a very small case. Its storage expansion is limited to one NVMe PCIe 3.0 x4 M.2 slot, while the board focuses on a small footprint, integrated Wi-Fi and Bluetooth, and support for 3rd Gen Ryzen processors.
Best For: Small-form-factor AM4 systems where Mini-ITX dimensions and integrated wireless connectivity matter more than multiple M.2 drives.
Pros:
- Mini-ITX design suits space-constrained PC builds.
- Includes an NVMe PCIe 3.0 x4 M.2 slot.
- Integrated Intel dual-band AC Wi-Fi and Bluetooth are convenient for compact systems.
- Offers a PCIe 3.0 x16 slot and support for 3rd Gen Ryzen processors.
Cons:
- Only one M.2 slot is listed, so it does not provide true multi-M.2 expansion.
- Uses the older PCIe 3.0 storage interface.
- Has two DIMM slots and supports up to 64GB of memory.
This is a sensible choice for a compact single-drive build, not for users prioritizing several internal M.2 SSDs. Its Mini-ITX layout and built-in wireless features help simplify small systems, while the single PCIe 3.0 M.2 slot keeps expansion modest.
Best White AM5 Pick – ASRock B650M-HDV M.2 White

Key Buying Factors for Computer Motherboards with Multiple M.2 Slots
Check Socket, Chipset, and Memory First
An M.2 slot does not make a board compatible with every processor. Match the motherboard to your CPU generation and confirm whether it uses DDR4 or DDR5 memory. AM5 boards require DDR5, while many AM4 and older Intel options use DDR4.
Understand PCIe Lanes and Shared Bandwidth
Two M.2 sockets may not operate identically. One can support PCIe 5.0 while another uses PCIe 4.0, and some sockets may disable SATA ports or reduce the bandwidth of another expansion slot when populated. Review the slot diagram in the manual if you plan to use several NVMe drives, a graphics card, or add-in cards together.
Evaluate Cooling, Capacity, and Connectivity
Look for M.2 heatsinks, especially when using high-performance Gen4 or Gen5 SSDs. Count SATA ports if you are building a NAS, and check 2.5Gb Ethernet, Wi-Fi, USB connectivity, and video outputs against your workload. Physical clearance also matters in Mini-ITX cases.
Who Should Buy Which Computer Motherboards with Multiple M2 Slots?
Choose a modern AM5 board if you want a new gaming or productivity system with longer upgrade potential. B550 models remain sensible for affordable Ryzen 3000- or 5000-series upgrades when you already own DDR4. Mini-ITX boards suit compact PCs, while NAS-oriented models are better for multiple SATA drives, always-on storage, and network-focused builds. An older Z490 board makes sense primarily when you already have a compatible 10th-generation Intel processor and DDR4 memory.
