Different Motherboard Form Factors
Motherboards come in various sizes and shapes, known as form factors. The form factor dictates the motherboard’s dimensions, mounting hole locations, and the number of expansion slots it can accommodate. The most common form factors are:
- ATX (Advanced Technology Extended): The standard size for desktop computers, offering a good balance of features and expandability.
- Micro-ATX: A smaller version of ATX, with fewer expansion slots but still compatible with most ATX cases.
- Mini-ITX: The smallest form factor, ideal for compact and low-power systems.
The table below summarizes the key differences:
| Form Factor | Dimensions (approximate) | Expansion Slots | Ideal For |
|---|---|---|---|
| ATX | 12 x 9.6 inches | Up to 7 | Standard desktop, gaming, high-end PCs |
| Micro-ATX | 9.6 x 9.6 inches | Up to 4 | Budget builds, smaller cases |
| Mini-ITX | 6.7 x 6.7 inches | 1 | Compact PCs, home theater PCs (HTPCs) |
Choosing the Right Motherboard
Selecting the right motherboard is crucial for a successful build. Consider these factors:
