I want to know that is keeping a cheap psu is safer or not. In my system I have a 250w psu. I am not interested in upgrading that. I have a 4Gb ram and a gpu attached. The gpu was purchased some week ago. I had notice that the system takes quiet a long time to boot. With a temperature monitor app I had seen it is rising to some extent. What can be cause of some. In my entire system I found that only psu is bit low powered other stuff are fine.
