Cooler Master has announced its UCP 900W power supply has achieved an 80 PLUS Gold rating. The 80 PLUS program rates power supplies at four different levels with The Gold level being given to units whose efficiency at a typical (50%) load is greater than 90%. Units must also maintain a 87% or greater efficiency at light and full loads. The UCP-900W managed a typical efficiency of 90.05% and an average efficiency of 88.24%. Cooler Master has several 80 PLUS certified power supplies, but this marks the first time one of its units have received the Gold rating. In fact, only about 3% of all power supplies tested are rated as 90% efficient or greater. Cooler Master plans to to showcase the UCP 900W at Computex this week. Cooler Master hasn't updated its web site yet, but you can take a look at the previous version of the UCP 900W to get an idea of what all this PSU has to offer.
