The main reason i ask is because the HDD also ran hot on this machine, would that be due to not enough power? Too much? I know that it wasent getting heat from other componets, because we had it out of the case, away from other things, and it was still very hot. Tell me your thoughts.

know anything about cars ?
Imagine you have a car that is capable of doing 100mph and you are trying to do 110mph .. then trying 120mph .. really pushing the engine to the maximum ..
thats the analogy of the power supply on the computer.
Just like the Car , the engine will eventually self destruct due to being pushed beyond the limits. Also though, most of the components will be totally stressed because they were never designed to run at that speed either. In the case of the PSU, the ELECTRICAL noise in form of high voltage spikes that haven't been filtered will constantly pound the components, like a hammer gently tapping away at a piece of metal until the metal cracks under fatigue. This constant beating with spikes causes the devices to overheat, eventually going into self destruction. I remember even now the Chemistry experiment back in the 60's where the Science Master connected a light bulb in series with a glass rod and fed mains Voltage across it. He then heated the glass rod , and as it got hot so the lightbulb started to glow. Electronic components are made from the same substance as glass rods!
When the PSU is running at less than full power it "cruises" so no strain , no pain. either on the PSU or the mobo.
The ability to deliver power is not the same as power being delivered. Power being delivered should equal the power being consumed. The power being consumed should be well within the tolerances of the supply. Never go 100%, you never know what stresses you are putting on the source or the load!
Hope that helps to clarify and if it doesn't I am only too willing to clarify until I have made myself perfectly clear.
