To answer questions 1 and 2, check out the Pinhead-227's sticky.

As for why a PSU is necessary, a large peltier like a 226W+ draws a lot of current and it's often more than what a computer power supply can deliver. Considering the rest of the computer components also need power, there's often not enough to go around (which leads to stability problems) or the TEC could overload the PSU altogether.

Also there are other TEC's that run on higher voltages that what a computer PSU offers which renders it almost useless (this is if you want to run the TEC at full load) as a power supply.
