Looking to reach the users who need lower wattage models, which is starting to account for a lot of PC builders as our components become more and more energy efficient, Silverstone has recently revamped their Strider Gold lineup, which previously only had a 1000W model, to now include 550W and 650W models. On my bench here today I have the 550W ST55F-G model.
