I believe that Rich Lanzillotto wanted to say "NRTL" where he said "UL" under 1., the times of the UL monopoly are over. Under 2. the power supply manufacturer can hardly claim such compliance, if anything maybe compliance with the conductive immunity and emission requirements. Even that is negated if you add circuitry and the housing. I would simply go for a complete retest.

The UL mark would be accepted by any NRTL you submit your system to. Otherwise you would have to be responsible for the safety compliance of the supply, a nearly impossible task. 2. As for FCC if the vendor claims of EMC Directive compliance includes conforming with harmonized emission standards like En 55022, then I think this could be OK. I would recommend you have a preliminary scan taken at a test lab however. Also the vendor should provide you with his Declaration of Conformity listing the evaluation standards.
