Summary: This was purchased to replace a dead PSU in a Dell XPS 420, and through research the Antec EA500 and EA650 were suggested as a good fit. The Green Power version appears to be a newer revision and did fit in my Dell case.
Summary: I've been using Antec PSUs for years as they are brilliantly made and put together. This unit comes with a three year warranty, although you should easily get well past this if protected with a good surge protector. This unit also comes with plenty of connectors and should cover most installations.
