Just an observation regarding Don's comment:

Last week I decided to do my radio shack reorganization (complete 
relocation of things) and one result is the main 12v line from my 
station Astron 50M PS, which is welding wire (no.6 awg?), to my main 
distribution strip was shortened from about 16 to 6-feet.  Resulting 
with 110w output on 2m FM vs 90w previous (guessing due to better 
voltage and/or lower coax loss).

One of the reasons for rearranging the station was to shorten 
cabling.  E.g. I eliminated a 20-foot runs of LMR-600 from both my 6m 
1000w PA & 2m 1500w PA.  240vac line is about 12-foot longer to my 
50v PS for the amps.  I don't expect to see much voltage sag with a 
load of 12A.  I only saw 1-volt sag in the original location.

Many of my 12v equipment power lines will also be shortened.  win-win!

Solder each power supply lead to a short length of #10 wire.  Insulate
the connection well.
