Common Slot Power Supplies - HP ProLiant DL160se - G6 Server Introduction Manual

servers not supporting Common slot architecture use HP industry standard
ProLiant 100-series G6 servers use highly efficient power supplies and DC power regulators to deliver
significantly higher power efficiencies.

Common Slot power supplies

The HP G6 Common Slot power strategy provides power supply commonality across supported
ProLiant G6 server lines. HP reduced the number of power supply designs, which reduces the number
of spares the customer must keep in the data center.
By incorporating "right-sizing," these power supplies have achieved efficiency ratings of up to 92%.
With the exception of the 1200W power supplies, they meet Climate Savers Gold requirements. The
1200W power supplies (AC and 48VDC) meet Climate Savers Silver requirements.
• 460W AC
• 750W AC
• 1200W AC
• 1200W 48VDC
The power loading efficiency curve for the 750W power supply shown in Figure 5 provides an
example of the high levels of power efficiency present in all new power supplies used in ProLiant G6
servers.
