Power Supply Unit HPE 656364-B21 1200W Metallic

The HPE 656364-B21 1200W Metallic power supply unit is a hot-swap, tool-less common slot (CS) PSU designed for HPE ProLiant servers. It accepts 100–240 V AC at 50–60 Hz, delivers 1200 W total power and carries 80 PLUS Platinum efficiency certification. The metallic enclosure and compact dimensions (38.1 × 190.5 × 86.3 mm) make it suitable for rack-mounted server systems such as ProLiant DL360p Gen8, DL380p Gen8, ML350p Gen8 and SL250s Gen8.

Advantages

This CS power supply offers high energy efficiency (rated around 94%) to reduce operating costs and lower data center power requirements. Its common electrical and physical design supports hot-swap, tool-less installation for fast replacement and minimal downtime. The modular CS form factor enables right-sizing for specific server configurations to avoid wasted or trapped capacity.
