Powering a NUC with an atx power supply?

[Piprian]

Hello!

I'm thinking of buying a "NUC11TNKi5" and I would like to know if it was somehow possible to run a gpu and the nuc off the same (preferably ATX) power supply.

I read somewhere that some NUC's have an internal 2x2 12v-24v plug but I can't find any information about this specific one.

I would also like to know if it is possible to attach an external power switch without having to solder anything.

Thank you!

Yes, it is certainly possible.

Per section 4.1.1.5 of the NUC11TN Technical Product Specification (TPS), you can use a supply providing any voltage in the range 12V-24V via either the external (5.5mm OD/2.5mm ID) plug or the internal 4x4 header (Pins 1, 2 PWR, Pins 3,4 GND). In either case, 120W must be suppled (60W per pin for internal header case). Note also that voltage supplied on pins 1, 2 of the internal header must be the same (+/-5%).

Hope this helps,

Sorry for reopening this but I have a question that is related.

Do you know of a practical way to have a power supply turn on/off with the NUC (which it is otherwise not directly connected to)?

The setup I have figured out so far is to have the NUC and a DC-ATX both powered by a 19v external power supply.

The last problem I have is that the power supply would keep the connected GPU running even when the NUC is off.

I have heard of somehow connecting the power LED header on the NUC to the PSON jumper on the power supply but before I try to figure that out, I would like to find out if there is an easier solution (preferably without a second power switch).

Would connecting the power LED header even work or would the PSU turn on too late for the GPU to be recognized by the NUC?

Thank you very much and sorry for the weird questions!

Piprian, Thank you for posting in the Intel® Communities Support.

In reference to your questions, just to let you know, what we recommend is to use the power supply that came with the Intel® NUC and connect it directly to the outlet, from our side there is no documentation about power supply customizations with the Intel® NUC.

Still, we encourage all the peers viewing this forum, that if they have any suggestions or recommendations for this scenario, to provide all the feedback and comments about this topic, we are sure they will be very helpful and useful for all the peers viewing this thread.
