The bottom one is the one you want to plug into the motherboard socket.

Not much if they are the same pin out in terms of wire placement (Black/Yellow/Yellow/Black). It's 12V and Ground. Some of the older motherboards have something called an EPS connector, which required an 8 pin connector, whereas new motherboards only require the 4 pin connector.

So if i connect the other cable instead of the one you told, the system should work without any problem no ? Do both cables give the same voltage ?

If they have the same pinout yes. Yellow cables are 12V in a PC, Black is Ground.
