## Long description

The Supermicro PWS-920P-1R2 is a 1U server power supply unit providing up to 920 W of continuous power with 80 PLUS Platinum efficiency. Designed for rack-mounted enterprise servers, it accepts AC input from 100 to 240 V at 50–60 Hz and integrates active power factor correction for stable operation across the full input range. The compact 1U form factor and card-edge connector make it compatible with Supermicro 1U backplanes, and the unit includes protective circuitry for over-voltage, over-current and short-circuit conditions.
Advantages
This power supply delivers high conversion efficiency (approximately 94%), reducing energy losses and heat generation in dense server environments. Redundancy and hot-swap capability allow continued system operation during maintenance or failure of a single unit. Integrated status LED makes it straightforward to monitor normal or abnormal operating conditions. Compliance with RoHS and Supermicro certification ensure material and quality standards suitable for enterprise deployments.
Suitable for
1U rack servers requiring a compact, high-efficiency PSU
Enterprise systems that need redundant, hot-swappable power supplies
Data centers and server rooms prioritizing energy efficiency and reduced heat output
