Power supply unit Supermicro PWS-920P-1R2 920 W 1U, 80 PLUS Platinum, AC 100–240 V

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

How to use

Install the PWS-920P-1R2 into a compatible Supermicro 1U chassis following the server manufacturer’s installation instructions and ensuring the card-edge connector aligns with the system backplane. Connect AC mains within the specified 100–240 V range and verify the LED indicator shows normal status after power-up. When used in redundant configurations, populate the redundant bay according to the chassis documentation to enable automatic failover. For hot-swap replacement, remove and replace the unit while the system is online only if the chassis supports hot-swapping; follow safe handling and electrostatic discharge precautions.

Usage recommendations

Use this PSU in compatible Supermicro 1U systems and data center environments where high efficiency, redundancy and hot-swap capability are required. Maintain ambient ventilation consistent with the server chassis specifications and perform regular visual checks of the LED status. Do not operate the unit outside the specified AC input range and ensure proper grounding to reduce the risk of electrical faults.
