A Guide to Choosing and Understanding Motherboard Sizes

Whether you're building a new computer from scratch or looking to upgrade your existing system, the motherboard, often referred to as the mainboard, is the backbone of any PC. It's the component that connects and communicates between all of your computer's most essential parts. If you're overwhelmed by the array of sizes and specifications available, fret not! This guide will dive deep into the various sizes of motherboards, helping you understand and choose the right one for your needs.

How To Choose a Motherboard:

Determine Your PC's Purpose:

Before you start shopping for how to choose motherboard, determine what you'll be using your computer for. A gaming rig has different requirements compared to a home theater PC or a workstation.

Compatibility Is Key:

Ensure that the motherboard is compatible with your CPU (both brand and socket type), RAM type (e.g., DDR4), and other essential components. When you learn how to choose a motherboard, this step is critical.

Features and Ports:

Some motherboards come with features such as built-in Wi-Fi, premium sound quality, or multiple USB ports. Determine what features you consider indispensable for your build.

Price Point:

Understand your budget. The priciest motherboard isn't always the best for your needs, but purchasing the cheapest can limit future upgrade potential.

Brand Reliability:

Opt for a brand known for longevity and excellent customer service. Brands like ASUS, MSI, Gigabyte, and ASRock are renowned in the industry.

How are Motherboards Made?

Motherboards are complex pieces of tech. For those curious about how are motherboards made, they primarily comprise several layers of printed circuit boards (PCBs). These layers are fused, with copper traces creating the routes for power and data transfer.

Design and Layout:

Through computer-aided design (CAD) software, engineers devise the layout of the motherboard, making sure each component has its precise location and operates effectively.

Lamination:

The multiple PCB layers get glued and then pressed together under elevated temperatures.

Subtractive Process:

Copper layers are introduced, and any excess copper is discarded, preserving only the necessary traces.

Component Placement:

Automated machines place various components, like capacitors, resistors, and the CPU socket.

Soldering:

All components get soldered in position, ensuring a robust and enduring connection.

Testing:

If you've ever wondered how are motherboards made to be so reliable, every motherboard undergoes stringent testing to guarantee its functionality and reliability.

Different Motherboard Sizes:

Motherboards are available in diverse sizes, recognized as form factors. If you're exploring motherboard sizes, these form factors offer a specific balance between size and functionality.

ATX (Standard ATX):

Size: 12 x 9.6 inches

Features:Boasts the maximum expansion slots, making it perfect for multi-GPU setups or high-end workstations.

Micro-ATX (mATX):

Size: 9.6 x 9.6 inches

Features: A more compact variant of ATX, perfect for both mainstream and budget-friendly builds with adequate slots for all essential components.

Mini-ITX:

Size: 6.7 x 6.7 inches

Features: Ideal for those researching compact motherboard sizes. It's best suited for small and portable builds, such as home theater PCs. However, its size limits expansion options.

Extended ATX (E-ATX):

Size: 12 x 10.1 inches and above

Features: Perfect for aficionados or users who need the utmost expansion, such as in server builds.

XL-ATX:

Size: 12.8 x 9.6 inches

Features: A tad larger than standard ATX, granting more space for components.

Which Size is Right for You?

Home & Office:

Micro-ATX or Mini-ITX. Both these motherboard sizes are compact, providing all necessary functions without the additional cost of unneeded features.

Gamers & Enthusiasts:

Standard ATX. This offers added expansion slots and can house powerful components.

Workstations & Servers:

E-ATX or XL-ATX. These offer vast space and expansion capabilities for those necessitating top-tier power and multitasking prowess.

Home Theater or Portable PCs:

Mini-ITX. Being the smallest among motherboard sizes, it's ideal for compact spaces and is more portable.

Conclusion:

Gaining a comprehensive understanding of the motherboard sizes available is essential to maximizing the efficacy of your PC build. A fitting motherboard acts as a reliable foundation, ensuring compatibility, performance, and long-lasting service for your system. Always account for your current needs and prospective expansion goals before deciding on a size. Remember, the optimal motherboard isn't just the one that snugly fits inside your PC case, but also aligns with your aspirations and needs for your computer.
