I have a mother board which is having 24 pin connection for the power, beside this the 24 pin PSU really only have 23 pins that make a connection and one is kept empty. I am using power connector which only has 20 pin with a 4 pin ADD ON clip as connector. So I want to know what the difference between the two is. Do I have to make any changes to ensure my mother board work fine or it is OK to run with 20 pin PSU.
