That wallwart will work,IF the barrel connector is 2.1mm x 5.5mm.
I used these,just make sure you have positive & negative correct,on a normal PC PSU,yellow is positive,black is negative:

Also,on a 4pin molex you have 12 volt (yellow) & 5 volt (red) each has it's own negative (black),it's closest to each,keep them paired

May not make a difference,but I keep em paired & have no issues.
You only use the 12 volt wires,you don't need the 5 volt,so just use 2 pins (yellow & black wire next to it) in your 4pin molex connector
