4. Setup

This section provides general guidelines for installing your ASUS Prime H270M-PLUS/CSM motherboard. Always refer to the detailed diagrams in the included user's manual for specific component locations and connections.

4.1. Preparing Your System

• Ensure your power supply is disconnected from the wall outlet.
• Place the motherboard on a non-conductive surface.
• Install the I/O Shield into your computer case.

4.2. CPU Installation

Carefully open the CPU socket lever. Align the CPU with the socket, ensuring the gold triangle on the CPU matches the triangle on the socket. Gently place the CPU into the socket without forcing it. Close the lever to secure the CPU.

4.3. CPU Cooler Installation

Apply thermal paste to the CPU if not pre-applied on your cooler. Mount the CPU cooler according to its manufacturer's instructions, ensuring it is securely fastened and the fan cable is connected to the CPU_FAN header on the motherboard.

4.4. RAM (Memory) Installation

Locate the DDR4 DIMM slots. Open the clips on both ends of the slot. Align the memory module with the slot, ensuring the notch on the module matches the key in the slot. Press down firmly on both ends of the memory module until the clips snap into place.

4.5. Motherboard Installation into Case

Carefully place the motherboard into the computer case, aligning the screw holes with the standoffs. Secure the motherboard with screws. Ensure the I/O ports align with the I/O Shield.

4.6. Storage Device Installation (M.2 / SATA)

For M.2 SSDs, insert the M.2 module into the M.2 slot and secure it with the provided M.2 screw. For SATA drives, connect the SATA data cables to the SATA ports on the motherboard and to your storage devices. Connect SATA power cables from your power supply to the drives.

4.7. Graphics Card (GPU) Installation

Insert your graphics card into the primary PCIe x16 slot. Ensure it is fully seated and secure it with the case's retention clip or screw. Connect any necessary PCIe power cables from your power supply to the graphics card.

4.8. Power Supply Connections

Connect the 24-pin ATX power connector and the 8-pin (or 4-pin) CPU power connector from your power supply to the corresponding ports on the motherboard.

4.9. Front Panel Connections

Connect the front panel cables (power button, reset button, HDD LED, power LED, USB, audio) to the corresponding headers on the motherboard. Refer to the motherboard's manual for exact pin configurations.

5. Operating

Once all components are installed and connected, you can power on your system. The motherboard's BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) will be the first interface you interact with.

5.1. BIOS/UEFI Setup

• Upon powering on, press the designated key (usually DEL or F2) repeatedly to enter the BIOS/UEFI setup utility.
• Configure boot order to install your operating system from a USB drive or optical disc.
• Adjust system settings such as date, time, fan speeds, and memory profiles as needed.
• Save changes and exit the BIOS/UEFI to continue with operating system installation.

5.2. Driver Installation

After installing your operating system, install the necessary drivers for the motherboard's components. These can typically be found on the included Support DVD or downloaded from the ASUS official website. Essential drivers include chipset, audio, LAN, and graphics drivers (if using integrated graphics).
