I've just returned my second dead 420 W Enermax. The first had a fan fail, the second ran for a day then failed to come on at all after I turned it off for the night. Since it's baseball season, I'm going to try a third, before I call it quits. Fortunately, Newegg does returns, but I'm starting to spend a fortune on shipping. I hope this isn't a sign the Enermax's quality is dropping.
