[sdiy] Computer Products brand Power Supplies

[The Peasant]

Based upon many years of experience with medical and industrial equipment, I 
have found small linear encapsulated supplies to last about half as long as 
unencapsulated types. This has been mostly attributed to heat buildup due to 
the insulating properties of the encapsulant, especially when coupled with poor 
external ventilation. These type of supplies are handy to place in small 
enclosed places, to their detriment. I have actually seen one manufacturer 
offer an "unencapsulated" version of their power supply to improve reliability.

If I was to use one I would keep it well ventilated and run well below it's 
output capacity, then you should be fine.

Take care,
Doug
