 Notes

  1. Power consumption data (watts) is measured from the wall power source and includes all power supply and system losses. Additional correction is not needed.
  2. "CPU Max" is defined as running a compute-intensive test application that maximizes processor usage and therefore power consumption.
  3. 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.
  4. Available for education institutions only.
