Hi, 

I have this power supply that I mounted on my robot. I gonna be using it for both 3, 5, 12V lines and later to connect an actual motherboard with Intel Core I9 CPU to it. But for now it's just 5, 12V lines for Arduinos and Motors. 

power supply spec

I tested the supply without a power resistor on 12v line and it seems to produce stable voltages. The video on converting an ATX power supply to a bench supply says that I might (or might not depending on the supply) need a power resistor:

Do you think I even need to connect this power resistor board that I made or not really.
