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

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.

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.
