Hmm, I didn't really look at the 5 volt specs. I'll do that.

He says he needs 35 volt power supply with 35 amps.

So if I wire together 12 power supplys (12v, 9a), voila, 36 volts at 36
amps.


You might take seven identical power supplies, each capable of
delivering at least 35 A from the 5 V line and connect them in series.
However, you would have to disconnect the 0 V DC from chassis on each
unit, so that the chassis of each power supply can be connected to the
protective ground.

If these are ATX power supplies, you would have to look at the startup
sequence, if these power supplies do not go on-line, when the mains is
applies. This may require some optoisolators.
