Mini UPS/USV for XU4 - Power output

Post by nicolazilio »

Dear all,

I would like to get this UPS to power my XU4

https://www.amazon.de/Eaton-Mini-Volt-I ... 092THB8TM

The specs mention that the UPS has 4 possible outputs:
  • 9V/3A
  • 12V/3A
  • 15V/2.4A
  • 19V/1.89A
All of the power supplies that I've used to date with my XU4 output at max 5V.

Is it okay to use a power supply that outputs at 9V or 12V? Or would I fry the board?

Thank you in advance.

No, XU4 is 5V only. Do not use anything above 5V. It will fry the board.

However you can use 5V Buck converter, to step down any of these voltages to 5V.
See the second photo in this post, my old XU4 based server.

You could, for example, select 12V, use it to power 3,5" HDD and branch it out to 5V Buck module.
