Power consumption and cooling
Introduction
If your power load is over 800 watts, and your power source is 90-115 volts, the 1110W power supply
is designed for your applications, and this site preparation guide is important. The 1110W power supply
has an efficiency rating that qualifies it for 80 PLUS SILVER status*.
For loads over 800 watts, observe the considerations and limitations presented in the following sections.
* The 80PLUS specification states that all SILVER power supplies are at least 85%/89%/85% efficient at 20%, 50%, and 100%
of rated output, respectively.
Power consumption and cooling considerations
An HP workstation with a 1110W 80 PLUS SILVER power supply might require more power than the
typical office environment can supply. Consider the following issues:
●
A fully loaded configuration might draw up to 15 amps of 110V power, leaving no power for other
accessories. A typical office has several 15 amp circuits.
●
An office air conditioning system must accommodate the extra heat generated by fully-loaded
workstation configurations.
●
Some environments might have power conditioning problems that prevent the reliable use of high
end workstation configurations.
●
If your workstation is powered from a 220V source and you meet HP configuration guidelines, you
do not need an uninterruptible power supply (UPS) for a maximum output power of 1250 watts.
