I could be wrong about a PSU complying with the Low Voltage Directive (LVD), as my experience only covers EN60950 which deals with IT equipment (which may include a PSU) rather than PSUs on their own. From an EMC point of view, a PSU has no intrinsic function and as you say shouldn't be marked as complying with the EMC directive (and, in my view, neither should PC graphics/sound/etc. cards as they have no function outside the PC). The thing about the CE mark is that there is no way of knowing from just the 'CE' exactly which EEC directives the manufacturer is claiming compliance with. There is much confusion generated from the assumption that CE marking is just about EMC, whereas the EMC directive is just one that a piece of electronics needs to comply with.
