Notes
- Power consumption data (watts) is measured from the wall power source and includes all power supply and system losses. Additional correction is not needed.
- "CPU Max" is defined as running a compute-intensive test application that maximizes processor usage and therefore power consumption.
- These numbers reflect a 23°C (73.4° F) ambient running environment. Increased ambient temperatures will require faster fan speeds which will increase power consumption. At 35° C (95° F), 50 W should be added to reflect increased power consumption.
- These numbers reflect no additional PCI Express cards installed.
