I have a question and i hope that you will answer.

What are the rails on PSU's and what are they for?

I always hear in your review something about 12V Rails & etc. but i have no idea what you are talking about. Please help me understand those terms.

Thanks in advance

A Rail is a general term that is used when describing the power lines in a computer power supply. Many modern PSU's will have multiply 12V Rails. The 12V, 3.3V and 5V lines are combined to give the total ratings.
