When building a PC, one of the most important decisions is the motherboard. The motherboard is the central hub of the computer, and it connects all of the other components together. The form factor of the motherboard determines its size and layout, and it also affects the number of expansion slots and ports that are available.
There are two main types of motherboard form factors: Mini-ITX and ATX.
Table of Contents
Mini ITX Motherboards
- The smallest form factor available
- Designed for small form factor builds, such as HTPCs and mini-ITX cases
- Typically, they have fewer expansion slots and ports than ATX motherboards
- Can still be used to build powerful PCs
ATX Motherboards
- Most common form factor
- Designed for standard tower cases and high-end builds
- Have more expansion slots and ports than Mini-ITX motherboards
- A good choice for users who need a lot of flexibility
Comparison Table: Mini ITX vs ATX
| Feature | Mini-ITX | ATX |
|---|---|---|
| Size | 6.7 x 6.7 inches | 12 x 9.6 inches |
| Expansion slots | 1-2 PCIe x16, 1-2 PCIe x1, 1-2 M.2 | 1-4 PCIe x16, 1-3 PCIe x1, 4-6 M.2 |
| Ports | 4-6 USB 3.0, 2-4 USB 2.0, 1-2 SATA III, 1-2 audio ports | 6-10 USB 3.0, 6-8 USB 2.0, 4-6 SATA III, 1-2 audio ports |
| Power handling | 150-250 watts | 300-600 watts |
| Cooling | More difficult | Easier |
| Cost | Less expensive | More expensive |
Choosing the Right Form Factor
The best motherboard form factor for you depends on your needs and budget. If you’re building a small form factor PC, then a Mini-ITX motherboard is a good option. If you’re building a high-end PC with a lot of expansion cards, then an ATX motherboard is a better choice.
FAQ: Mini ITX vs ATX Motherboard
Q: What is the difference between Mini-ITX and ATX motherboards?
A: The main difference between Mini-ITX and ATX motherboards is their size. Mini-ITX motherboards are much smaller than ATX motherboards, and they typically have fewer expansion slots and ports. ATX motherboards are larger and have more expansion slots and ports, making them a good choice for users who need a lot of flexibility.
Q: Which motherboard form factor is right for me?
The best motherboard form factor for you depends on your needs and budget. If you’re building a small form factor PC, then a Mini-ITX motherboard is a good option. If you’re building a high-end PC with a lot of expansion cards, then an ATX motherboard is a better choice.
Q: What are the benefits of using a Mini-ITX motherboard?
Mini-ITX motherboards are smaller and more compact than ATX motherboards, making them a good choice for users who want to build a small form factor PC. They are also typically less expensive than ATX motherboards.
Q: What are the benefits of using an ATX motherboard?
ATX motherboards have more expansion slots and ports than Mini-ITX motherboards, making them a good choice for users who need a lot of flexibility. They are also typically more durable than Mini-ITX motherboards.
