1. A power supply for powering a data processing system comprising hardware resources to provide computer implemented services, the power supply comprising:
a power socket connected to an external power source;
a gas mover;
a heating element;
a primary power supply adapted to receive electrical power directly from the external power source through the power socket and provide conditioned power to the hardware resources while a temperature of the primary power supply exceeds a threshold temperature;
a startup power supply adapted to receive the electrical power directly from the external power source through the power socket and selectively provide conditioned power to:
the gas mover, and
the heating element;
a power manager adapted to:
prevent the primary power supply from attempting to provide the conditioned power while the temperature of the primary power supply is below the threshold temperature, and
while the temperature of the primary power supply is below the threshold temperature:
increase, with the gas mover, the heating element, and the startup power supply, the temperature of the primary power supply to exceed the threshold temperature;
an enclosure comprising two gas vents, wherein the gas mover, the heating element, and at least a portion of the primary power supply are positioned along a gas flow path between the two gas vents;
a first temperature sensor positioned to measure the temperature of the primary power supply; and
a second temperature sensor positioned to measure a second temperature of the gas mover,
wherein the first temperature sensors and the second temperature sensor are adapted to provide the measurements of the temperature of the primary power supply and the second temperature of the gas mover to the power manager.
