      The Supermicro PWS-1K11P-1R is capable of supplying 850W low-line and 1010W high-line output power at 90% efficiency. Enjoy the simplicity of active power factor correction (PFC) and automatically correct DC input for a full range of voltages. 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.
