Here’s a list of the common slots and connectors you’ll find on a motherboard, along with brief descriptions of their functions. I’ve also provided the general names you can look for if you’re seeking images online.
1. CPU Socket
- Description: The slot where the CPU (Central Processing Unit) is installed. This socket type must match the CPU’s specific model (e.g., Intel LGA, AMD AM4).
- Look for: A large square grid with many small pins or holes in the center of the motherboard.
2. RAM Slots (DIMM Slots)
- Description: These slots hold RAM sticks (DDR3, DDR4, DDR5), which are long, narrow components. Modern motherboards typically have 2 or 4 DIMM slots.
- Look for: Long vertical slots, often color-coded (for dual-channel memory support), near the CPU socket.
3. PCIe Slots (Peripheral Component Interconnect Express)
- Description: PCIe slots are used for adding expansion cards such as GPUs (graphics cards), sound cards, network cards, or even additional storage controllers.
- PCIe x16: Used primarily for GPUs.
- PCIe x4, x1: Used for smaller expansion cards like sound cards, Wi-Fi cards.
- Look for: Long, horizontal slots. The PCIe x16 is usually the longest slot, while PCIe x4 and x1 are shorter.

4. M.2 Slot
- Description: M.2 slots are used for connecting high-speed M.2 SSDs directly to the motherboard for storage. Some M.2 slots also support Wi-Fi or Bluetooth modules.
- Look for: A small, horizontal slot usually placed between the PCIe slots and RAM slots. It looks like a short slot with a screw mount at the other end for securing an M.2 drive.
5. SATA Ports
- Description: These are used to connect SATA SSDs, HDDs, and optical drives to the motherboard. The SATA interface handles data transfer between the storage devices and the motherboard.
- Look for: L-shaped ports, usually located on the edge of the motherboard. They’re often grouped together in a cluster and may be placed at a right angle to the board.
6. Power Connectors (ATX and CPU Power)
- Description: These connectors are used to supply power to the motherboard.
- 24-pin ATX power connector: Provides the main power to the motherboard.
- 8-pin CPU power connector: Supplies power specifically to the CPU.
- Look for: A large 24-pin connector located along the right edge of the motherboard (ATX), and a smaller 8-pin connector near the CPU socket (CPU power).
7. Front Panel Connectors
- Description: These small connectors link the motherboard to the power/reset buttons, indicator LEDs, and sometimes the speaker of your computer case.
- Look for: Small rows of pins, often labeled with PWR, RESET, HDD LED, and so on, usually located on the lower edge of the motherboard.
8. USB Headers (Internal USB Ports)
- Description: These ports are used to connect front-facing USB ports from the PC case to the motherboard.
- USB 3.0/3.1 headers: Provide fast USB ports.
- USB 2.0 headers: Provide standard USB ports.
- Look for: Small rectangular connectors, often placed at the lower edge of the motherboard.
9. Audio Header
- Description: This connector is used to connect the front panel audio ports (for headphones/microphone) of the case to the motherboard.
- Look for: A small block of pins labeled AUDIO, often located near the PCIe slots.
10. CMOS Battery
- Description: A small coin-cell battery used to keep the system clock running and to store BIOS settings when the computer is turned off.
- Look for: A round, silver coin-sized battery usually placed near the lower-right section of the motherboard.
11. Chipset
- Description: The chipset is the primary controller of the motherboard and manages communication between the CPU, RAM, storage, and expansion cards. It’s usually covered by a small heatsink.
- Look for: A square or rectangular component with a heatsink near the PCIe slots.
12. Fan Headers
- Description: Small connectors used to power and control case fans and the CPU cooler fan.
- Look for: Small 3-pin or 4-pin connectors labeled CPU FAN, CHA FAN, or SYS FAN.
