The Supermicro PWS-1K28P-SQ is an 80 Plus Platinum power supply capable of supplying 1280W output power at 95% efficiency. Enjoy the simplicity of active power factor correction (PFC) and automatically correct AC input for a full range of voltages and super quiet fans for a more peaceful environment under normal operation. Features a card edge connector for connection with the backplane of compatible Supermicro 1U systems. This power supply is designed to not only provide you reliable power to your Supermicro server but also protects it from over voltage, over current and short circuiting via protective circuitry embedded into the unit.
