We are building a special digital signage system. We want to know if we can power all the devices inside it from a single power supply.
We want to use the following equipment inside it.
Power Source: Meanwell 12V Power Supply. Model?
DEVICES TO BE POWERED:
PC
Kit with i3 + 4GB RAM + 64 GB SSD- Model No. NUC5i3RYH (On the manual it states that it will work 12-19V)
Normally it has an external 19V power adapter.

LED Strip Lights
Multiple LED Strip Lights which work with 12V
LED driver HV9921N3 datasheet: 
A/D Board for LCD Panel
A/D Board is connected via LVDS cable to the LCD Panel directly.
On the manual it states that the A/D Board can work between 12-19V.
Normally it has an external 19V power adapter.
Questions:
If we use this above mentioned single Meanwell LED Driver Power Supply with enough wattage/amps, will it power all the devices at the same time without any problem?
Are there any risks to the devices?
Another Option: Is it possible to power the LED Strip Lights and/or the A/D Board directly from the Intel Nuc's Motherboard?
Thank you for your support.

Will this be controlled by a recorded MIDI track with automation lanes, or live by CC controllers?

What does this have to do with a DAW system?

Nothing. Probably a SEO hack.
