* 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: ●...
890 watts and 1110 watts, respectively. See dissipation on page 4 HP recommends an online continuous UPS that provides a layer of insulation from quality problems. This type of supply also allows control of output voltage and frequency regardless of input voltage and frequency.
● To reduce the risk of overload: ◦ Do not exceed the rated load of any single power distribution unit (PDU). ◦ Do not load a single National Electrical Manufacturers Association (NEMA) 5-15 receptacle with more than 15 amps. ◦ Do not load a single International Electrotechnical Commission (IEC) 320-1/C13 receptacle with more than 10 amps.
4-or 8- GB DDR3-1333 MHz Registered DIMMs. Estimation does not extend to 16 GB DIMMs. Five SAS 15K HDDs. For maximum power consumed per graphics card, see product QuickSpecs at http://www.hp.com/go/productbulletin/. Maximum graphics power supported with an 850W power supply is one 175W graphics card, or two 100W graphics cards.
Cooling considerations To ensure proper ventilation and cooling for your workstation, observe the following guidelines. ● Keep your workstation in an area where the airflow is not obstructed. ● Keep the workstation off from surfaces where dust can gather. ● Remove dust on the front panel bottom (vent area) and the rear fans with a small vacuum, compressed air, or dust rag.
