I have a media cabinet which houses a bunch of media players/routers/alarm system etc.
The target output voltages for each component is between 9V and 24V. This is currently powered by an LED power supply with a few step down buck converters to the target voltages. The LED power supply is very noisy and I would like to replace with a fanless PSU which I have lying around. (Silverstone NIGHTJAR SERIES SST-NJ520).
The power requirements of my components are below:
The above total wattage is well inside the specs of the psu.
The PSU specs state that at +12V the max load is 43A, at -12V 0.5A. The question is can I safely go from -12V to 12V to make use of the 43A restriction or should I instead consider adding an Step Up Boost converter from 12V to 24V before stepping down to the required 9V, 12V, 19V?
I've attached the manual in case it helps
Many thanks in advance.
