Query: Faulty Power Supply

It has been 4 months since my 1-year warranty expired the system would not power up since yesterday. I could not find any useful posting on DELL's website but thanks to google saw these postings. when I got my computer originally the microphone would not work. DELL troubleshot it as a motherboard problem when in reality it was a problem with the sound card driver which I found out myself. I realized how pathetic DELL's support is then. So I am not going to waste time by calling them now. I am off to Fry's to get a power supply. Any recommendation on what brand/type I should look for?
