Is IEC 61010 needed for a populated PCB within a unit?

My company make a product (a populated PCB within a unit) that needs to be plugged into a PSU, much like a laptop PSU, to be able to work. It isnt required to operate with large current flow, so a lot of engineers are saying that they dont think we would need to add it to our scope, BUT i think, as we are supplying an externally bought, pre-made PSU and putting it within OUR part number when we resell the unit as a kit (as such) that we should be treating it the same as any old part number, therefore getting some kind of test done to ensure that when being used with our pcb, it doesnt exceed any kind of tolerances within the safety standard. can you tell me your views?

Just because you have an external mains-dc power supply, it doesn't automatically make the product "safe".
Safety standards, such as 61010, cover a number of risks including:
- Hazardous Voltages
- Energy Hazards
- Fire
- Mechanical hazards (including sharp edges/corners)

I would recommend applying the LVD, and appropriate standard, to the whole product. If the external PSU is suitably rated for its application and has trusted 3rd party certification marks *, the rest of the assessment shouldn't be that onerous

* - these aren't mandatory, but I would never use an external PSU that didn't have them. There are plenty out there, from reputable manufacturers, and its really not worth the hassle trying to verify that something with "just a CE mark" on it is actually safe
