linear power supply for a NUC ... 12-19 VDC

149.75.74.107

any opinions on what is best? With such a wide range does it make any difference what I use?

Go by what the manufacturer recommends and keep in mind the amount of Power required. Volts X Amps = Watts so be sure the power supply can source enough current (Amps). And keep in mind that NUCs (and other PCs) will draw more power during boot-up.

  Comes with a 19V supply but it can run from 12-19VDC hence the question.... is there any reason to run it a particular point in that range?
  
  Baseboard Power Requirements
  19V, 90W AC-DC power adapter
  with detachable power cord.
  12-19V DC input range
  International cords available

    Since Power = Volts X Amps you will need a higher current (Amps) rated power supply when running 12 Volts vs 19 Volts.
    90W / 19V = 4.7 Amps
    90W / 12V = 7.5 Amps
    And it's not clear if those ratings are peak or average (probably peak). If you go with a 12V power supply a unit that can output 10 Amps should have sufficient head room to spare. Make sure the cabling connections are reasonably tight.

My guess is the latter - E-Stat 10:40:01 09/21/24 (0)
I'm very happy with an HDPlex linear which has that capability although I use it to power an ultraRendu at 7V.

Most anything would be better than the crappy switchers found in general purpose computers.
