Supermicro PWS-920P-SQ 920W server power supply

What this unit is

The Supermicro PWS-920P-SQ is a new 920W server power supply designed for rack-mount chassis. It delivers +12V at 75A and a 5V standby rail at 4A. The compact 2.99" x 1.57" x 14.17" form factor fits standard redundant bays. It targets administrators who need reliable AC power for mission-critical workloads.

The deciding specification

This module is an AC power supply, not a Battery Backup Power unit. It provides continuous 920W output without integrated battery runtime. Buyers requiring hold-up time during mains loss must add a separate BBP module such as the PWS-1K03B-1R to the same chassis. The choice hinges on whether you need pure AC redundancy or combined AC-plus-battery protection.

Who this suits and who should look elsewhere

Suits operators populating Supermicro 1U to 4U servers with hot-swappable AC redundancy. Suits builds where 920W per module matches the platform power budget. Not for buyers who need integrated battery backup in a single slot. Not for systems that demand a different input voltage range or connector layout than the standard redundant form factor provides.
