What is the Difference Between Micro ATX and Mini ITX?

🆚 Go to Comparative Table 🆚

Micro ATX and Mini ITX are two popular motherboard form factors that differ in size, PCIe slots, RAM slots, and price. Here are the main differences between them:

  1. Size: Micro ATX measures 244 x 244 mm (9.6" x 9.6"), while Mini ITX is smaller at 170 x 170 mm (6.7" x 6.7").
  2. PCIe Slots: Micro ATX motherboards typically have four slots, while Mini ITX motherboards have only one PCIe slot. This difference can impact the compatibility and expandability of the system, especially for heavy-duty graphics cards.
  3. RAM Slots: Micro ATX motherboards support up to 4 memory slots, while Mini ITX motherboards only support two RAM slots, with each slot capable of holding up to 16 GB RAM. This limitation can be a factor if you need more than 32 GB of RAM in the future.
  4. Price: Mini ITX motherboards are generally more expensive than Micro ATX motherboards, as ITX is considered a premium market, while mATX is seen as a budget option.

In summary, if you need more expandability, RAM slots, and PCIe slots, a Micro ATX motherboard might be a better choice. However, if you prefer a smaller form factor and are willing to pay a premium for it, a Mini ITX motherboard could be the right option for you.
