Didn't run it (the calc), but did read the page.

Our supplies had 100% proper continuous load ratings.

We would never make a supply operation declaration label that
declared peak wattage, unless the supply was custom, like an ionizer
supply or such.

Our LVDC supplies were a rated rail at a given wattage with a
voltage variance (regulation) of a declared amount, and a ripple of a
declared amount at that full load (ripple spec).

It doesn't get much simpler, but reminds me of the false
declarations made by car stereo folks in the 70's. You get what you
pay for, and you have to research what you buy.

Life is simple. We build things for our use. One must not
over-complicate the techno devices in life. Go with the flow.
