Power dissipation for the HP Z820 Workstation
The following table contains typical system configurations for an HP Z820 Workstation.
2x CPU Power 2x Midrange graphics
50-75W each (4) (5)
2x High-end graphics
75-150W each (4) (5)
2x High-end graphics
150W-225W each (4) (5)
80W, 95W 795-883W* 839-980W* 980-1125W***
115W 884-928W* 928-1025W** 1025-1164W***
130W,135W 910-963W* 954-1060W** 1060-1209W***
150W 955-999W* 999-1096W** 1096-1245W***
Low risk = * May not need to reference details of the Site Preparation Guide.
Medium risk = ** May need to reference details of the Site Preparation Guide.
High risk = *** Site Preparation Guide reference is required.
●
Asterisks refer to risk when using the workstation configured with a 1125W power supply.
●
The workstation with an 850W power supply should be configured to be <850W maximum power.
NOTE: All configurations have two CPUs (1), 16 DIMMs (2), five hard disk drives (3), two optical disk drives, and typical
additional expansion cards. Configuring fewer hard disk drives or optical drives has some impact on system power.
Power consumption is highly dependent on software use. The table values represent examples of maximum power consumption
per configuration and may not represent actual usage.
1
For maximum power consumed per CPU, see product QuickSpecs at http://www.hp.com/go/productbulletin/.
2
4-, 8-, or 16-GB DDR3-1600 MHz Registered DIMMs. Estimation does not extend to 32-GB DIMMs.
3
Five SAS 15K HDDs.
4
For maximum power consumed per graphics card, see product QuickSpecs at http://www.hp.com/go/productbulletin/.
5
Maximum graphics power supported with an 850W power supply is one 150W graphics card, or two 75W graphics cards.
