1. I come to believe that my system's PS is suspect. I would like to 
replace it. How does one figure out which PS to get? What determines 
what specific model one buys: size of the case (desktop), type of the 
MB (mine is an 865), etc.? Do all PSs come with the same number of 
connectors? Any preferences? Since I may have to leave the box open 
for a while, I'd like one with a quiet fan.

What's inside the box now is a:

Powmax
ATX Switching PS
Model No. LP-8800D

It's a 400W model and it's ATX 2.03 and ATX12V 1.1 compliant, 
whatever that means. I would like to go up a notch to a 450W.

If there is primer on PSs, please point me in the right direction.

2. The slot fan I got has two power plugs: a male and a female. I 
connected the female to a connector from the PS. Nothing happens. Do 
these things start spinning if the temperature goes to certain level 
or am I supposed to find a second connector for the male plug, 
although I don't see any free ones?

I will be grateful for your help.
