I have a number of ATX supplies that are dead. I want to try to repair them, instead of spending more loot on replacements. What I'd like to know is , what are the most common parts that you need to repair ATX power supplies? I know, a lot of electrolytic capacitors. But what kind of diodes (voltge/amperage/device number), rectifier bridges (the same), power FET's (device numbers) and other common parts should I be stocking? I don't want to make the 25 mile drive to the parts store to find those parts. Thanks for any help you can provide!
