Motherboard Architecture
The central nervous system of modern computing in 2026.
Understanding the PCB
The Printed Circuit Board (PCB) is more than just a mounting surface. In 2026, high-end motherboards utilize up to 14 layers of copper to handle the immense signal integrity required by PCIe 6.0 and DDR5/DDR6 memory lanes.
Form Factor Comparison
Choosing the right size determines your expansion capabilities and thermal headroom.
| Form Factor | Dimensions | Max RAM Slots | Best Use Case |
|---|---|---|---|
| ATX | 305 × 244 mm | 4 - 8 | Workstations & Gaming |
| Micro-ATX | 244 × 244 mm | 4 | Balanced Builds |
| Mini-ITX | 170 × 170 mm | 2 | SFF (Small Form Factor) |
The VRM Hierarchy
The Voltage Regulator Module (VRM) is responsible for converting 12V power from your PSU into the precise voltage required by your CPU. Modern boards use 105A power stages to maintain stability under heavy AI processing loads.
- Chokes: Filter the power to provide a clean signal.
- Capacitors: Store energy to prevent sudden voltage drops.
- Heatsinks: Crucial for maintaining VRM efficiency during overclocking.
