    The Supermicro PWS-1K41P-1R is an 80 Plus Gold power supply capable of supplying 1400W output power at 92% efficiency. Enjoy the simplicity of active power factor correction (PFC) and automatically correct AC 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. Rest easy knowing your hardware will be up and running with a mean-time between failure (MTBF) of greater than 150,000 hours and an LED indicator to keep you informed on normal/abnormal conditions for your PSU. This power supply is redundant to safe-guard your system from power failure and allows for hot-swap replacement to eliminate system downtime. All materials contained comply with RoHS requirements and is certified by Supermicro.
