I've got a brown THIN Vsense wire running together with the 3.3V line at pin 11, this can be sure that i can get this mod with 10ohm fixed resister connect in series and 1k ohm pot connect in parallel............

but how about the 5V and 12V Vsense lines, i've got no Vsense line for 5V and 12V on my PSU, only one wire go through each pin........the fat one............. so is that mean no modding i can do to 5V and 12V?????

what u can do is open up the PSU and find the main vReg chips on the PCB, measure some voltages and find which one is controlling the 5v and 12v lines, then look up that IC online and find which pin is the FB pin and put a VR between that FB line and ground.

now this is dangerous because PSUs have big charges stored in them, so mod at ur own risk.

also i dont know how to find out what value VR u should use
