It's a new brand that we just spotted - we're going by the fact that they are made by Channel Well who also makes Antec, Enermax, etc. Unlikely to be a Piece o' Crap and the 450 could well be one of the best values out there... The first reports sound promising - quiet and cool running.
. Depends on your particluar risk-tolerance. If you only buy stuff approved by Consumer Reports, then stick with the old conservative brands. Otherwise, take a chance. Note that they don't have the "Warranted only through mfr. " wording that's becoming common on Newegg - a good sign. And they've been OOS on some models at least twice and some models have even been dropped from the list as apparently they have to wait for another ship to come in before they'll have more. So they must be selling pretty well.
. Unless something comes along that looks like a better value by then, an XClio will be the next PSU I buy. I've been doing this PC stuff for over 25 years - I think I have a pretty good handle on what's what.
