Cpu, case and chipset fans 99.001% (I made that number up, but its realistic! ) of the time are +12v.
What you should know about having a small or cheap power supply is that when a system powers on those motors draw 3 times more than they actually use.
In fact anything with a motor has a huge power spike at initial startup, although it doesnt take much to move a fan they do draw a huge amount of amps at boot. Once a fan or motor is spinning the amps drop immensly.
But overall dont read too much into any of this.
Most power good supplies and even some cheap ones can power more than they are rated for.
A good company can sell a power supply that can exceed the rated draw and still clean up the power from the wall socket, a poor power supply is just over rated and can not meet its draw ratings with out burning up and/or it does not give clean even power.
The circuitry and parts used in a power supply makes all the difference IMO.
I live in an old house in florida where nasty storms hit all of the time and the power always fluctuates, this has a direct bearing on the power supply, good ones will keep the power even, poor ones will jump up and down.
again I rant, sorry

J.C.GARCIA wrote:so then the more amperage , current , you have on the 12v rail the better. i suppose this is what you mean
