Nucleus wattage

Hi there,
I’m planning on getting a linear power supply for my Nucleus. I have one of the newer models since I just purchased it a month ago. My question…It’s 19V and uses how many watts? My research tells me it’s like 60 watts, but my dealer insists it is 90 watts? If someone from Roon support can reply, that would be very helpful!
Thanks

On my Nucleus+ (NUC7i7BNB), the stock power supply is 19V 65W. You can look for the official specifications here: Power Adapter and Power Cord Specifications for Intel® NUC Products

Also, woudn’t your stock power brick give you this information?
