GROUNDING STRUCTURE

Transient Voltage Suppressors (TVS)

Transient Voltage Suppressors (TVS) are safety devices used to protect against excessive voltage. All motherboard models of MSI are equipped with TVS. When the voltage abnormally rises, the TVS switches from a high-resistance state to a low-resistance state, diverting the excessive voltage to ground. This helps prevent circuit damage caused by high voltage.

solid pin design

The 4-pin, 8-pin, and 24-pin power connectors of MSI motherboards are all designed with solid pins. The solid pin design allows for a more stable transmission of 12V power to the CPU, even when handling high current loads.

Advantages of Solid Pin Power connector

Improved stability : Larger contact area enhances stability during power delivery.
Low impedance : Solid pins offer low impedance, enabling efficient power flow.
Strong durability : The solid pin design ensures strong durability, capable of withstanding demanding conditions.
Suitable for high-current applications.

Anti-corrosive Stainless Steel IO Shield

An extra layer of sponge materials along with corrosive resistance IO Shield to help improve static electricity and reduce electromagnetic radiation noise from the system as well as much more durable compare to traditional IO Shields.

* The image above is an illustrative reference. Please refer to specification pages for more details.

Over Current Protection

MSI motherboards prioritize safety with the embedded Overcurrent Protection (OCP), ensuring crucial components such as the USB ports, DDR memory, PWM IC, and CPU are shielded from excessive current. This proactive defense mechanism curtails the risk of damage or malfunction due to power surges, promoting long-term system stability. This commitment to safeguarding your hardware underscores MSI’s dedication to producing motherboards that prioritize durability and stability.
