If the power is drawn from an actively cooled expansion card (for example: High-end graphics card) that emits its waste
heat directly into the ambient air and not into the interior of the device. The requirements of the expansion card for the
temperature of the intake air (inside the device) must be observed.

Operation only permissible in conjunction with power supply unit 850 W
