Rosewill teamed up with Enhance Electronics for the updated Capstone G series that features six PSUs with capacities ranging from 550W to 1200W. We evaluated the 1200W unit to see how it fares against the competition.

Rosewill initially partnered with Super Flower, which made the company's entry into the power supply market easier, since the first Rosewill PSUs featured very high performance-per-dollar ratios. However, a company cannot rely entirely on a single manufacturer, and the truth is that demand for Super Flower's services weighs on its ability to keep up. In addition, the prices of Super Flower's high-end platforms aren't as affordable as they used to be. When enthusiasts weren't as familiar with Super Flower, good performance and low prices brought new customers in. However, when a company no longer needs exposure, then it makes sense to raise prices, matching the competition.

Higher costs, coupled with the fact that Super Flower cannot meet excess demand any more, probably pushed Rosewill to approach Enhance Electronics for its new Capstone G line (even though the older Capstones employed Super Flower platforms).
