Power dissipation for the HP Z800 Workstation
The following table contains typical system configurations for an HP Z800 Workstation.
2x CPU Power 2x Midrange graphics 50-75
W each (4)
2x High-end graphics 75-150
W each (4) (5)
2x High-end graphics >150
W each (4) (5)
80W 630-675 W* 675-810 W* 810-950 W*
95W 715-760 W* 760-900 W* 900-1030 W**
130W 800-845 W* 845-980 W** 930-1110 W***
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 required.
●
Asterisks refer to risk when using the workstation configured with a 1110 W power supply.
●
The workstation with an 850 W power supply should be configured to be <850 W 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- or 8-GB DDR3-1333 MHz Registered DIMMs. Estimation does not extend to 16-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 850 W power supply is one 175 W graphics card, or two 100 W graphics
cards. For maximum graphics power, see product
QuickSpecs at http://www.hp.com/go/productbulletin/.
