The Power Supply works amazing and got here really quick. My only problem was that although it was listed as compatible with the old Dell PC I was installing in, it did not fit the case. I had to use steel cutters to widen the gap in the metal on the back of the case to allow the power cord to be plugged into the supply. Aside from this everything was perfect.
