it makes sense now ,I recognised the resistor and its purpose , was just very confused when I saw it on the 12v rail in the picture , but any way if only I knew about this before a had blown up my previous 2 (cheap) power supplies, this should be on the reprap wiki (or is it already?)
The 5 ohms resistor should be on the 5 volts rail (wrong on the picture). This resistor stabilizes the voltage when a power peak is needed from the power supply. It often appends with cheap power supply. I paid this one $15!
