Whilst Dave is correct it did not answer your question ! All the
positives will be connected together as will all the negatives. The
reason that there are three pins in the plug for each rail is that the
current rating of each pin is only 4 amps.

Each pin only being rated for 4 amps sort of makes sense. However,
the total amperage output of the Optiplex Power Supply is 18 amps,
which would cause me to assume that the amperage across each pin must
be 6 amps (18amps/3pins), though I don't have an ampometer to confirm.

This might actually work in my favor, since the ham radio is rated for
12 amps input and I could just use two of the pairs to supply it. Or
would it be better to push the total 18 amps to the radio?

Again, this is all contingent on the ham radio working on the flat 12
volts instead of 13.8 volts.

Thank you both for your comments.

Kind Regards,


Gary
