Re: Replacement power supply for Dell Dimension 9150

I just replaced the power supply in y Dell XPS 400/Dimension 9150 courtesy of my Dell extended warranty.  Thankfully the fan noise is gone but I also received an unexpected bonus.  The PC is running much faster.  Apps are more responsive, downloads faster, etc.  It was almost like adding additional RAM.  The only explanation I have is that the fan was dragging the power supply voltage down and the CPU was not receiving full power.  My PC was 4.5 years old and left to run continuously 24/7. You may wish to check with Dell replacement parts for their price on a power supply befor going to a third party.  The PS has a multitude of power cables attached to it that a third party PS may not have.
