Introduction
The Z4 G5 has been redesigned to deliver support for the latest processor, memory, graphics, and storage technologies.
There are three cy-90% efficien rated power supplies that qualify for 80 PLUS GOLD status*.
The Z6 G5 has been redesigned to deliver support for the latest processor, memory, graphics, and storage technologies.
There are two 90% efficiency- rated power supplies that qualify for 80 PLUS GOLD status*.
In order for the system to turn on with these new power supplies, the system side panels must be fully seated. The system
will error and provide a Three Red/4 White beep code.
* The 80 PLUS specification states that all GOLD power supplies achieve cy V at least 87%/90%/87% efficien at 115 and
90%/92%/89% efficiency at 230V for 20%/50%/100% of rated output, r espectively.
Power consumption and cooling considerations
An HP workstation might require more power than the typical office environment can supply.
An 1125W fully loaded configuration might draw up to the system’s maximum rating of 12A at 110V power, leaving no
power for other accessories.
• An office air conditioning system must accommodate the extra heat generated by fully loaded workstation
configurations.
• Some environments might have power quality problems that prevent the reliable use of high-end workstation
configurations. Possible problems include power failure, voltage sag, voltage surge, voltage spike, brownout, line
noise, frequency variation, and switching transient and harmonic distortion.
• If your workstation is powered from a >200V source and you meet the HP configuration guidelines, you will not need an
uninterruptible power supply (UPS) to achieve maximum power output.
Power consumption limitations
– The Z4/Z6 G5 1125W power supplies are capable of multiple output power wattages depending on the input voltage.
It is not recommended to operate in an environment that drops below 90V for any reason (for example, brownout or
line sag) as the AC brown out voltage detection circuit for the power supply may be triggered and shut the PSU down
unexpectedly. A UPS is highly recommended to achieve maximum output power when used at 100V.

775W PSU Not recommended 775W 775W 775W
Uninterruptible power supply (UPS)
• What is a power interruption?
A power interruption can take the form of a power failure , voltage sag, voltage surge, voltage spike, brownout (blackout)
(drop), line noise, frequency variation, and switching transient and harmonic distortion.
• What is an uninterruptible power supply (UPS)?
3
A UPS provides power when the primary 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 ine Interactive, and ffline UPS enables the – s otandby/ ffline, l o c s online ontinuous. A tandby/
computer to draw power from the main AC power source until there is a power interruption. It protects against power
surges, brownouts, and power failures.
A l iine nteractive UPS protects against power problems, power failure, sags, surges, brownouts, and line noise. The
supply offers voltage regulation by bumping the mains voltage up or down. his feature improves the quality of AC power T
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 o c d -c nline ontinuous UPS is the most dependable solution. It is also referred to as a ouble onversion UPS. It provides
protection against power failures, sags, surges, brownouts, line noise, spikes, frequency variations, switching transients,
and harmonic The inverter is always on and supplies the supported load with clean, regulated power and the distortion. ,
incoming power is always fully conditioned. Constant voltage and frequency regulation switching to significantly reduce
and from the battery, increas the life and reliability of the UPS.ing
• How do you select a UPS?
Use a UPS for a fully loaded workstation configuration that operates in a poor power grid area. The UPS must be rated at
least 2kVA for the 1125W PSU. A UPS is necessary because without line conditioning to guarantee the minimum input
voltage the maximum output power is limited. configurations and maximum See Power consumption on page 4 for
power estimates.
HP recommends an online continuous UPS that provides a layer of insulation from quality problems. The type of supply
also allows control of output voltage and frequency regardless of input voltage and frequency. To reach the 1275W
(1125W PSU) of output power, you must maintain 115V, ideally.
CAUTION! Check with your power provider to see if your facility can reliably maintain greater than 90V power. If 90V
cannot be guaranteed to your workstation, the input voltage source might blow the fuse in the power supply or trip the
breaker. For reliable workstation operation under heavy loading, use a UPS because it provides reliable voltage levels.
• To reduce risk of a power interruption :
– Do not exceed the rated load of any single power supply (PSU). For maximum voltage/current ratings, refer to the
product’s ratings label.
– . Only use the power cord included with the product
– In general, verify that each power source circuit can safely provide the current needed for equipment that draws power
from it.
