- Function: Expand the system’s capabilities.
- Types: PCIe x16, x8, x4, x1, with x16 being common for graphics cards.
5. Storage Connectors
Connect storage devices such as HDDs, SSDs.
- Types:
- SATA Ports: For traditional HDDs and SSDs.
- M.2 Slots: For NVMe SSDs offering faster data transfer.
- U.2 Connectors: For high-performance SSDs.
6. Power Connectors
Distribute electrical power from the power supply to the motherboard and components.
- Main Power Connector: Usually a 24-pin connector.
- CPU Power Connector: Typically an 8-pin or 4-pin connector.
7. BIOS/UEFI Chip
Stores firmware that initializes hardware during boot.
- Function: Provides low-level control and setup for hardware components.
8. I/O Ports
Allow connection of external devices.
- Common Ports:
- USB ports
- HDMI or DisplayPort
- Ethernet port
- Audio jacks
- PS/2 ports
9. Battery (CMOS Battery)
A small coin cell battery that powers the BIOS/UEFI firmware when the system is powered off.
- Function: Maintains BIOS settings and system clock.
