What does it mean if a power supply exceeds standard operating temperatures?
Exceeding standard operating temperatures means running your power supply when the ambient temperature falls outside the operating temperatures for which it is rated. Sometimes this happens — you can't predict every possible usage scenario, and you can’t always guarantee a stable environment.
Why should a power supply have a wide operating temperature range?
Depending on the application, a power supply with a wide operating temperature range may provide better reliability and a longer operating lifetime, prevent the need for a cooling fan or other special design consideration for thermal management, and reduce the overall cost of your system.
What temperature should a power supply be rated at?
High 90 fahrenheits is ok. Celcius is another matter, it's close to waters boiling point for f*** sake. That is a lame sentence. High temperature can be higher than rated temperature or something else. That power supply is rated at 50c by the way. 40c is average, 50c rating is good. Apply for the warranty and see how it goes.
What is a good ambient temperature for a power supply?
Some applications may require ambient operating temperatures as low as -40 degrees Celsius and as high as +85 degrees Celsius, or an even wider range. A number of factors can influence the ambient temperature that a power supply is subjected to in a given application, including the following:
How do I choose a power supply?
When you're selecting a power supply for your system, you'll need to consider its ambient operating temperature range. Running your power supply within its specified operating temperatures are essential for optimizing its performance, preventing overheating and breakdowns, and extending its lifespan.
How should a power supply be operated under temperature test?
The unit under temperature test should be operated under normal load conditions in accordance to supply voltage concerning worst-case condition until the temperature has stabilized. Common power supplies support a wide input voltage range to cover worldwide AC mains networks.
