Take an ATX power supply and cut off the last 2 pins on the 20 pin connecto=
r with a utility knife.  The hard part will be figuring out the exact pinou=
t because it will most likely be different from normal ATX.  pinout.ru migh=
t be a good place to start.  Then take a pin extractor tool and move the wi=
res around accordingly.  The aux connector should fit the 4 pin one just fi=
ne.  Triple and quadruple check everything before attempting to power it up=
