Sizes Compared
The MATX (Micro-ATX) motherboard measures 244mm × 244mm, while ATX boards are larger at 305mm × 244mm. MATX fits compact cases, whereas ATX requires standard or full-tower cases with ample internal space for mounting.
Expansion Capabilities
ATX boards excel in expansion, featuring multiple PCIe slots for GPUs, sound cards, and other add-ons, along with robust I/O ports and advanced power delivery. MATX boards have fewer slots and connectors, limiting hardware upgrades but offering sufficient ports for basic setups.
Compatibility and Case Fit
- ATX Cases: Accommodate all motherboard sizes, including ATX, MATX, and ITX.
- MATX Cases: Support MATX and smaller boards like ITX but exclude ATX due to size constraints.
Always match your motherboard to case specifications to avoid installation issues.
Performance and Thermal Considerations
ATX boards often include superior cooling solutions and support high-end components like multiple GPUs for demanding tasks. MATX boards may have thermal limitations in smaller cases but remain efficient for everyday use.
Recommended Use Cases
For high-performance needs, such as gaming or professional workloads, ATX provides better scalability and stability. MATX suits budget-friendly or space-constrained builds, like home offices or compact systems.
Consider your case dimensions, performance goals, and budget to select the ideal fit.
