Notes
- Power consumption data (watts) is measured from the wall power source and includes all power supply and system losses. Additional correction isn't 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 require faster fan speeds which increases power consumption. At 35°C (95°F), 50W should be added to reflect increased power consumption.
