Last week, I took on a name in power supplies I had never reviewed before. This week, it's more of the same as I take on yet another newcomer to my lab: Tagan. They sent me one of their new PipeRock II units at 680W, and are anxious to see how I made out with it. This is an Impervio built unit that looks very promising.

Come on in, and we'll all find out how it did together.
