servers not supporting Common slot architecture use HP industry standard5 power supplies. All 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 up to 92% efficiency up to 92% efficiency up to 90% efficiency up to 90% efficiency 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.
