Power consumption limitations IMPORTANT: The HP Z800 Workstation power supply is capable of continuously supplying 1110 watts output power when the input voltage is greater than 90 volts. If the input voltage is less than 90 volts for any reason (for example, brownout or a line sag), the maximum output power is limited to 890 watts. The HP Z800 Workstation power supply is capable of continuously supplying 1250 watts of output power when the input voltage is greater than 105 volts. If the input voltage is less than 105 volts, but greater than 90 volts for any reason, the maximum output power is limited to 1110 watts. To take advantage of providing 1250 watts, a UPS is highly recommended. IMPORTANT: The HP Z820 Workstation power supply is capable of continuously supplying 1125 watts output power when the input voltage is greater than 90 volts. If the input voltage is less than 90 volts for any reason (for example, brownout or a line sag), the maximum output power is limited to 890 watts. The HP Z820 Workstation power supply is capable of continuously supplying 1275 watts of output power when the input voltage is greater than 105 volts. If the input voltage is less than 105 volts, but greater than 90 volts for any reason, the maximum output power is limited to 1125 watts. To take advantage of providing 1275 watts, a UPS is highly recommended. ● What is a power interruption? A power interruption can take the form of a power failure, voltage sag, voltage spike, brownout, over-voltage, line noise, frequency variation, switching transient, and harmonic distortion. ● What is an uninterruptable power supply (UPS) battery? A UPS battery provides power when the primary power source is unavailable or insufficient. It keeps the computer powered on and operational in the event of a power interruption. There are three types of UPS-Standby/Offline, Line Interactive, and Online Continuous. A Standby/Offline UPS enables the computer to draw power from the main AC power source until there is a power interruption. It protects against power surges, drops, and blackouts. A Line Interactive UPS protects against power problems, power failure, sags, surges, brownouts, and line noise. This supply offers voltage regulation by bumping the mains voltage up or down. This feature improves the quality of AC power to the supported load, reduces the number of transfers to and from battery mode, reduces the number of brief power interruptions to the load when switching to and from battery mode, and improves battery life. An Online Continuous UPS is the most dependable solution. It is also referred to as a DoubleConversion UPS. It provides protection against power failures, sags, surges, brownouts, line noise, spikes, frequency variations, switching transients, and harmonic distortion. The inverter is always on and supplies the supported load with clean, regulated power and the incoming power is always fully conditioned. Constant voltage and frequency regulation means far less switching to and from the battery which increases the life and reliability of the UPS. 2 Power consumption and cooling

What is a power interruption?
A power interruption can take the form of a power failure, voltage sag, voltage spike, brownout,
over-voltage, line noise, frequency variation, switching transient, and harmonic distortion.

What is an uninterruptable power supply (UPS) battery?
A UPS battery provides power when the primary power source is unavailable or insufficient. It
keeps the computer powered on and operational in the event of a power interruption.
There are three types of UPS—Standby/Offline, Line Interactive, and Online Continuous. A
Standby/Offline
UPS enables the computer to draw power from the main AC power source until
there is a power interruption. It protects against power surges, drops, and blackouts.
A
Line Interactive
UPS protects against power problems, power failure, sags, surges, brownouts,
and line noise. This supply offers voltage regulation by bumping the mains voltage up or down.
This feature improves the quality of AC power to the supported load, reduces the number of
transfers to and from battery mode, reduces the number of brief power interruptions to the load
