Most computer companies dont design and build power supplies for thier products. ie Innovators uses MeanWell supplies. Look at the label.
Its rated for 45W, really 42.6W-ish.
(5V * 3A) + (12V * 2A) + (-12V * 0.3A) = 42.6W
I have no idea what the MB + CPU + RAM draws, say 1.0A at 5V. An IO Card, say, 300mA. Add a 3.5" drive, about 600mA, CDROM (ie 32x), 1.0A. Whats the total amperage? 2.9A! Not a
lot of margin huh :) The number may be less or more. What about surge? It will be higher. The unit was not engineered to draw max current. At least I dont design my products to draw at the maximum. 50% to 75%. Oh and the amperage at 12v is near the max = 2.0A. Sure, the supply can provide more power than this but its not good to run it at the max levels. They have margin built in also.
What is the current drawn at the AC side?
With a 1Amp fuse at 100VAC. 100VAC x 0.707
is 70.7V RMS. Factor in the ineffeciency
and it about right.
I dont think the supply is unsafe.
