It is worth mentioning that many low cost competitors do not mention the preferred mounting orientation, and some do not even have an installation manual on their website!
An incorrectly mounted power supply will get too hot resulting in premature electrolytic capacitor degradation, catastrophic semiconductor failure or even a fire due to transformers overheating.
Other general power supply mounting considerations include the following:
- Make sure there is adequate space around the power supply to allow air to circulate.
- Do not block off vent holes on convection cooled supplies or restrict air inlet or outlet ports on fan cooled supplies.
- In the event fans are employed within power supply, a system, or an enclosure make sure the airflow direction for all fans are the same
