Thank you
Looks like there are a few different voltages and a few different amperage requirements among the NUC power supplies:
However, if you have a 19V model and have one that needs <= 90 W, it looks like the one pictured above should work if the size of the plug is compatible (2.5x5.5 mm, a pretty common size for voltages around this range IIRC but not entirely standardized--and very rarely labeled on the device itself, which also appears to be the case above). If not, there are adapters you can get to "convert" plug sizes if the specs are otherwise within range of your device, though finding one that works as-is might be easier (maybe or maybe not cheaper) or less ugly in the long run.
However, some NUCs appear to have higher power needs (up to 500W!) or work on different voltages (some are 12V), so I'd verify your model number on the list I linked to above to be sure.
Thank you, it’s this one Intel NUC Kit NUC6CAYH Product Specifications
I’m getting an 8gb 65 gb ssd for $80. Okay deal? It should outperform a raspberry pi right?
Looks to need 19v, 65w
I also have a 19.5v one, will it fry it?
The one pictured is 19v at 4.75 amps or very nearly 90 watts. Factor in inefficiencies and it will probably work.
