Voeding Supermicro PWS-920P-1R2 920 W

The Supermicro PWS-920P-1R2 is a redundant 920 W power supply unit for 1U server systems, certified 80 PLUS Platinum for up to 94% efficiency. It accepts AC input from 100–240 V at 50–60 Hz, includes active power factor correction (PFC), and connects via a card edge connector to compatible Supermicro backplanes. The unit is designed for hot-swap redundancy and includes protective circuitry against over-voltage, over-current and short circuits. Physical dimensions are 79 mm (W) x 40 mm (D) x 336 mm (H), and the PSU complies with REACH and RoHS environmental standards.

Advantages

The PWS-920P-1R2 delivers high conversion efficiency with 80 PLUS Platinum certification and 94% typical efficiency, reducing energy losses and heat. Redundant design with hot-swap capability helps maintain system availability during PSU replacement. Built-in protections for over-voltage, over-current and short circuit improve server safety, while an LED indicator provides clear status reporting. A high MTBF (greater than 200,000 hours) indicates long-term reliability for continuous server operation.

Suitable for

• 1U Supermicro server systems requiring redundant power
• Datacenter racks and blade enclosures with compatible card-edge connectors
• Environments where energy efficiency and reduced heat output are important

How to use

Install the PSU into a compatible Supermicro 1U chassis by aligning and seating the card edge connector with the server backplane. Configure the server for redundant power operation according to the chassis and motherboard documentation. Use the LED indicator to verify normal or abnormal PSU status. To replace the unit, perform a hot-swap following your datacenter safety procedures to avoid system downtime.

Recommendations

Operate the PSU within the specified AC input range (100–240 V, 50–60 Hz), ensure proper airflow in the 1U chassis for cooling, and verify compatibility with the server backplane before installation. Follow ESD and hot-swap safety procedures when replacing the unit.
