Motherboard short circuit means that the circuit on the motherboard is abnormal, and the current mistakenly passes through the Southbridge chip, causing the chip to burn out beyond the capacity. Although the motherboard short circuit will cause a certain risk to the Southbridge chip, whether it will burn out depends on the severity of the short circuit and the quality and protection measures of the chip itself.
If the short circuit only causes the chip to suffer temporary overload, it may only cause temporary failure, but not burn out; However, if the short circuit is serious and lasts for a long time, or the protection measures of the chip are not perfect, the possibility of the South bridge chip being burned will increase. Therefore, the rational use and protection of the motherboard can reduce the risk of the Southbridge chip burning.
Many of the power supplies of various modules on the motherboard are separately supplied, such as the CPU power supply, the induction power supply of the north and south bridge chip are different power chips to provide power conversion, if the motherboard short circuit is a power short circuit it is possible to burn the power chip and the corresponding chip.
