IMPORTANT: Before selecting power supplies, HP recommends that you run the HP Power 
Advisor to determine the right size power supply for your server configuration. HP Power Advisor 
is available as both an online tool, running directly from the HP website, and as a downloadable 
tool. Instructions on how to download and use the tool are available on the HP website 
(http://www.hp.com/go/hppoweradvisor).
