I have acquired a used intel NUC8i5BEH which is supposedly a 90W model. The PSU supplied from the eBay seller is a 19V 3.42A PSU which is 65W. Supposedly this was supplied when it was purchased... The NUC runs and powers up without any apparent issues but I'm unsure if this is an issue I should ask them to rectify? Does running this at a lower wattage cause issues that I need to address? Am I being too cautious?
