Rosewill have grown from providing what were inexpensive PSUs with little to no extra features into something much more interesting for those who do not need a 1000W PSU.  The new Quark-550 that [H]ard|OCP recently tested is a good example, it is fully modular, it has a single 12v rail with a capacity of up to 45A and internal components from both Nippon Chemi-con and Rubycon.  Once strapped to their torture bench, [H]ard|OCP saw decent results, in line with the competition for stability and efficiency but as the unit retails for $100, roughly $20 higher than other comparable units it did not receive an award.  If you find it on sale it is still a good choice for a mid-range build.

"Rosewill was a Newegg "house brand" that has broken out to other retailers and you might have seen its name on all types of products. Today we are seeing what Rosewill accomplishes when it brands a 550 watt "Platinum" PSU. The 550W PSU market is crammed with competition…good competition at good prices."
