Just an FYI, I was able to revive a fairly new Dell power supply XW784 aka DPS-250AB-28 that was out of a Dell Inspiron 531S that wouldn't turn on. There was a lone 16v 1500uf cap that had bulged. I didn't desolder it but just pulled it out with pliers, I noticed that one of the leads just pulled right out of the solder joint as if it wasn't attached. I soldered a new Rubycon in and it started right up!
