This utility model provides a server with an independent power supply airflow, relating to the field of server design technology. Its key technical features include: a chassis and a power supply, wherein the power supply is located inside the chassis. The chassis includes a base plate and side plates. The power supply is fixed to the base plate. A cold air vent is provided on the side plate of the chassis. A power supply air inlet is provided on the power supply. A power supply baffle is provided on the side of the power supply with the power supply air inlet. The power supply baffle is a hollow cuboid with two openings, which are respectively used to connect the cold air vent and the power supply air inlet. By introducing cold air from outside the chassis through the cold air vent, the hot air from the CPU's rear end is prevented from affecting the power supply, thereby reducing the temperature of the power supply air inlet and keeping the power supply in a better temperature environment. The direct advantage is that it prevents the power supply from derating or stopping output, ensuring normal server operation and indirectly extending the power supply's lifespan.
