"Cooler Master has been offering power supplies for a couple of years now and the quality of their products has improved over time. They are famous for their enclosures and heat sinks. With the UCP series, Cooler Master is now offering a line of premium power supplies that feature the latest in power output, efficiency and looks. Today, we are going to examine the UCP 900 Watt. The 900 watt version is the second most powerful in the UCP series. There are three models, the 700 watt, 900 watt and the 1100 watt. A great feature of this power supply is that it is 80Plus Silver certified, which is currently quite rare in PC power supplies. According to the 80Plus test report, its typical efficiency is around 88 percent!"
