Hi everybody I am looking for a ~ 400 Watt power supply for my computer that
can work on 120V AC [grid] as well as on my 120V DC Battery Bank at my
ranch!
So far i have found only ones that were unpleasantly expensive and available
only in far away markets...

Apparently the specification 'full range' is common to distinguish from
manual or automatic switching voltage modes, and that hopefully guarantees
also that they may just have a regular bridge rectifier input stage (as most
PS have in their high range) and a PWM Switcher / transformer that can
handle the longer pulses needed and reaches the required voltage...

Or can anybody think of some tricks that may be applicable to make any old
PS work on 120V DC?
