I have a need for some UL certified power supply they need to handle a mini itx core I3 and a couple of drives. most are stamped UR that does not meet spec. thanks in advance
UL's North America component certification program includes two marks. The traditional UL in a Circle Mark which is intended for end-products and complete components and the backwards "UR" Mark which is for components intended to be installed into another device or product. UL Listed Components are suitable for both field and factory installations. UL Recognized Components are suitable for factory installation only since they have conditions of use, also known as Conditions of Acceptability; that need to be met in the end product application.
UR stands for "Underwriters Laboratories Recognized" and should be just as good. Which UL standards aren't met by a UR PSU, compared to one with the "UL" mark on it?
