Bigbruin.com has posted a review on the Thermaltake Toughpower QFan 650W Power Supply

The aesthetics of the unit are a little bit different from the norm, but everything is well done. In use, the Toughpower QFan 650W power supply is very impressive; providing excellent voltage regulation and near silent operation. Most high quality power supplies these days aim to be quiet, but Thermaltake takes a few extra steps to guarantee it on this unit.
