3. Overview of Components
Familiarize yourself with the layout and connectors of your B450 motherboard.



4. Setup and Installation
Before starting, ensure your computer is powered off and unplugged from the power outlet to prevent hardware damage.
4.1. Install CPU & Fan
- Lift the CPU socket locking lever completely.
- Locate the CPU socket and CPU pins. A small triangle marking on the socket denotes Pin One.
- Carefully place the CPU into the socket, ensuring the triangle on the CPU aligns with the triangle on the socket. Do not force the CPU.
- With the CPU in the socket, press one finger on the middle of the CPU, lower the locking lever, and lock it into the fully locked position.
- Apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.
- Install the CPU cooler and ensure it forms a tight seal with the CPU.
- Connect the CPU heatsink's 4-pin fan power connector to the 4-pin CPU fan header (CPU_FAN1) on the motherboard.
- Ensure the 4-PIN DC power supply is plugged in to power the CPU.

Important: Make sure the motherboard supports your CPU. Do not turn on the computer if the CPU cooler is not installed to prevent overheating.
4.2. Install Memory (RAM)
The motherboard provides two DDR4 DIMM slots, each supporting up to 32GB for a maximum total of 64GB.
- Wrench the latches on both sides of the memory slot outwards.
- Align the memory module with the notch in the slot. Memory modules have a foolproof design and can only be installed in one direction. If it doesn't fit, try flipping it.
- Insert the memory into the slot firmly until it clicks into place.
- Flip the latches on both sides of the slot inwards to lock the memory.

Important: Use memory of the same capacity, brand, speed, and chips for optimal performance. Dual-Channel mode requires two memory modules.
4.3. Install Expansion Cards (PCIe)
The motherboard includes one PCIe 3.0 x16 slot and one PCIe 2.0 x1 slot.
- Select an available PCI Express slot.
- Align your expansion card with the slot.
- Press the expansion card firmly until it is fully seated in the slot.

Important: Always power off and unplug the system before installing or removing expansion cards. Incorrect installation can cause short circuits.
4.4. Connecting Storage Devices (M.2 & SATA)
M.2 Slot
- Insert your M.2 SSD into the M.2 slot at a 30-degree angle.
- Secure the M.2 SSD in place with the provided screw.
SATA 3.0 Connectors
The motherboard has four SATA 3.0 connectors (SATA1~4), each supporting a single SATA device (HDD/SSD) with 6Gb/s interface speeds. Connect your SATA devices using SATA cables.
4.5. Power Connections
Ensure your power supply is turned off before connecting power cables.
- 24-pin Main Power Connector (ATXPWR1): Connect the main 24-pin power cable from your power supply to this connector.
- 4-pin +12V Power Connector (ATX12V1): Connect the 4-pin CPU power cable from your power supply to this connector.
Important: A powerful power supply (at least 500W) is recommended for stable system operation. Insufficient power can lead to instability or boot failures.
4.6. Front Panel & Other Connectors
- F_PANEL1 Connector: Connect your chassis's front panel power LED, power switch, HDD LED, and reset switch cables here. Refer to the motherboard diagram for correct pin alignment.
- SPEAK1 Connector: Connect the chassis speaker here.
- FAUDIO1 Connector: Connect your chassis's front panel audio jacks (Mic-in, Line-out) here.
- USB1 (USB 2.0) Connector: Connect your chassis's front panel USB 2.0 ports here.
- USB30_1 (USB 3.0) Connector: Connect your chassis's front panel USB 3.0 ports here.
- COM1 (Serial Port Connector): Provides a serial port via an optional COM port cable.
- CPU_FAN1 & CSYSFAN1 (Fan Connectors): Connect your CPU cooler fan to CPU_FAN1 (4-pin) and system fans to CSYSFAN1 (4-pin). The 4-pin connectors support intelligent PWM speed regulation.
Important: Incorrect connection of front panel headers can cause devices to malfunction or be damaged.
5. Operating Instructions: BIOS Setup
The BIOS (Basic Input and Output System) manages hardware parameters and initiates the system startup process. It allows users to modify basic system configurations.
5.1. Enter BIOS Setup
When the computer starts up, the BIOS performs a self-test. Once completed, a message like "Press DEL key to enter Setup Menu" will be displayed. Press the DEL key to enter the BIOS setup utility.
- If you miss the message, you can restart the computer by turning it off and on, pressing the Reset button on the case, or pressing Ctrl+Alt+Delete simultaneously.
Important: BIOS functions may vary slightly depending on the specific product version.
5.2. Reset BIOS
If you need to restore default BIOS settings to resolve issues, you have a few options:
- Enter BIOS setup and press F11 to load optimized defaults.
- Short the Clear CMOS jumper on the motherboard.
Important: Always ensure the computer is powered off and unplugged before clearing CMOS data to prevent damage.
6. Maintenance
Regular maintenance helps ensure the longevity and stable performance of your motherboard.
6.1. CMOS Discharge
To clear the CMOS (Complementary Metal-Oxide-Semiconductor) settings, which can resolve certain boot issues:
- Ensure the computer is completely powered off and unplugged from the power outlet.
- Locate the JCMOS1 jumper on the motherboard.
- In its initial state, the jumper covers pins "1" and "2".
- To discharge, pull out the jumper cap and place it to cover pins "2" and "3".
- Wait for approximately 3 minutes for the discharge to complete.
- After discharge, restore the jumper cap to its initial position (covering pins "1" and "2").
Important: Always power off and unplug the system before performing a CMOS discharge.
6.2. General Handling and Care
- Always handle the motherboard by its edges to avoid touching sensitive components.
- Store the motherboard in an anti-static bag when not in use.
- Keep the motherboard free from dust and debris. Use compressed air for cleaning.
- Ensure proper airflow within your PC case to prevent overheating.
