If you note there are many yellow red and orange wires in parallel ... i
have a 400w psu here and have 4 yellow (12) 5 red (5) and 5 (3.3) orange
wires for the 18A nominal supplied ! and in fact it is told 10 A per wire
...
for the 12V ... is feasible to have a different supply, with separate PV
unit and batteries ? 12V is not so exigent on the nominal voltage, and a
directly connected battery could fit the requirements ..., either a PbSO4
o a NiMH one ... also, using for fans an unregulated 24V supply, using the
12 V out only for a switched speed control ??
apart for fans and disks on a computer what are the other 12V users ???
