Nobody called me on my nonsense so I will: The 5.1V 3.5A = 17.8W was the PSU _rating_ whereas the 12.1V 0.7A = 8.5 W was actually _meassured_. I’m not a EE and I don’t understand the power section of that board, but something to look out for.



Yes, it didn't seem to make sense butI figured it was a typo and the more important thing was the increased SSD speed.

What is the rating of your bigger supply?

And presumably what you were measuring is the average Amps/Watts, not the peak.


Exactly. The bigger supply is the (excellent) https://pine64.com/product/pinepower-120w-desktop-power-supp... and the output I used is rated as: 65W Output/5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A
