Re: Fan voltages - am I slowly breaking my PSU??

I understand that if you lower the voltage the current increases to match the wattage, but is this case on the psu? will the wattage lower as a result of a rated component connected to the wrong power input?
If you keep the wattage the same, then a change in voltage will affect a change in current.

However, as a fan has a basic resistance to it, lowering the voltage will lower the current, and hence lower the wattage required to run it. (Lower voltage = Less work done spinning the fan = lower wattage)
