A Switch Mode Power Supply (SMPS) with a 20 + 4 pin configuration and a power rating of 450 watts is a type of power supply commonly used in computer systems. The 20 + 4 pin configuration refers to the main power connector that provides power to the motherboard. It consists of a 20-pin connector that can be split into a 4-pin connector, allowing compatibility with older motherboards that require a 20-pin connection.
The 450-watt power rating indicates the maximum power output that the SMPS can provide. This power supply is capable of delivering up to 450 watts of power to the computer components, including the motherboard, CPU, graphics card, and other peripherals.
SMPS units are designed to efficiently convert the incoming AC power from the wall outlet into the appropriate DC voltage levels required by the computer components. They typically include various protection features, such as overvoltage protection, overcurrent protection, and short circuit protection, to safeguard the computer system from potential damage.
When selecting an SMPS, it is important to consider the power requirements of the computer components to ensure that the power supply can adequately meet the system’s needs.
