Power consumption and heat dissipation

Power consumption and heat dissipation specifications are available for multiple 850W and 1110W power supply configurations. To review available specifications, see http://www.hp.com/go/ quickspecs.

To reach zero power consumption, unplug the workstation from the power outlet or use a power strip with an on/off switch. For additional information about power-saving features, see the operating system documentation.
